When time and funding permit, each flower (each plant species) will have its own page, and its own PDF, and eventually its own PPT so that professors and students have plenty of material on Guatemala (and Honduras, etc) to study.

Savanna-like area (Lake Yaxha, Peten, Guatemala) covered with parasitic Cuscuta vines

Posted July 23, 2019

About every two months (from August 2018 through July 2019) we visit the south shore of Lake Yaxha, the southern area of Parque Nacional Yaxha Nakum Naranjo. On each visit we noted lots of the parasitic Cuscuta vine wandering around on the ground, searching for plants to visit and suck their life-system. This July, from the boat (kindly provided every month by the park administrators IDAEH and CONAP), I noticed a yellow glow about 10 meters inland from the shore. So I asked the lanchero to go towards the shore so I could step off and inspect the orange color. Turned out it was a series of savanna-like areas with the ground literally covered with Cuscuta.

This pano was taken with an iPhone Xs. We will be preparing a full report with our dozen panoramas of this area by Dr Nicholas (Hellmuth) plus nice close-up macro photographs by Maria Alejandra Gutierrez.

We do field work at the park itself one week every month all year (April, 2018 when invited to do a test visit, then August through July for the initial first-phase (exploration and discovery phase).

There are several species of Cuscuta, in different ecosystems around the Americas. We have Cuscuta growing around bushes that stand out of the water in beaver-dam flooded areas on our family farm in the Missouri Ozarks. From a distance it looks identical to the Cuscuta from Guatemala (except here in Missouri it has adapted to snow and ice during the winter).

There is also lots of Cuscuta around Solola, en route to Lake Atitlan, Guatemala. Over the years we have found and photographed many locations with Cuscuta vines in different ecosystems of Alta Verapaz, Guatemala. I love the color and thin spaghetti diameter of the vine. The flowers are miniature and pretty. How this vine survives is great reading (just Google it).

I am curious how many botanists or ecologists have documented Cuscuta-filled flat areas of this nature before. We are finding a lot of ecosystems at Yaxha not fully documented in the literature of peer-reviewed journals.

 


 

Bogs, Swamps, Lagoons, Lakes, Rivers, Ox-bows Diverse humid ecosystems await you at Yaxha

Posted June 14, 2019

If you are a professor of ecology, botany, zoology, entomology, you will find species at Yaxha that will showcase your capability as a scholar. This is because there are more different ecosystems in this one single park than in most other parks. During the field trips (one each month) we have found and photographed a diversity of ecosystems around Yaxha, Nakum, and Naranjo that will help totally rewrite all the 1960’s-1990’s research done elsewhere in Peten.

Panorama of Savanna of 3 Fern Species, discovered by the team in April 2019; revisited in June 2019. This area has unforeseen diversity: it is a bog, a swamp, a savanna of ferns, and a sibal (sawgrass ecosystem). Plus has the specific Acoelorraphe wrightii palmetto palm and Crescentia cujete trees of grass savanna definition of Peten and Belize (but no pine trees and no bushes with sandpaper leaves (Curatella americana, Chaparro). So the grass savannas of the Nakum area of the park are distinctly (and unexpectedly) different than the savannas of nearby Belize.

Panorama of the unexpectedly large Savanna East of Nakum, discovered several months ago at Aguada Maya, Poza Maya. Each of these ecosystems has a different micro ecosystem every 50 meters.

To our knowledge this project (FLAAR Mesoamerica cooperating with IDAEH and CONAP) is among the first to use the concept of panorama photos to document the ecosystem diversity. Our goal is to show the world what is available for you to experience when you visit Parque Nacional Yaxha Nakum Naranjo. Since the sawgrass and ferns are so high we bring ladders (endless kilometers hike) so we can use a several-meter high Gitzo tripod so our panorama system (iPhone Xs, Google Pixel 3XL, Nikon D810 or Canon EOS 1DX Mark II or our other cameras) can record the plant diversity in each of the micro ecosystems.

Since there is so much to see in this park it helps to stay several days. The Hotel Ecolodge El Sombrero is located next to the entrance. You do not need 4WD to reach the hotel nor the parking lot to entire the Yaxha ruins. Boats are readily available to cruise Lake Yaxha, the cenotes at the west end, and the Rio Ixtinto near the west side of Isla Topoxte.

To reach Nakum, try only in the dry season and only with high axel 4WD (or hiking by foot, with a guide). To reach Naranjo, an impressive area of acropolises, palaces, temples and pyramids, a high axel 4WD is essential (except during the driest month of the year, perhaps April).

 


 

Edible roots from Guatemala

Posted Jun. 7, 2019

The root is the lower part of a plant, they are almost always underground, although there are also aerial and aquatic roots. Roots are in charge of holding the plant to the ground, absorb water and minerals, synthesize hormones and store nutrients.

Roots are usually edible, some types of them are:

  • Napiform: root thickened by the storage of nutrients and shaped like a turnip.
  • Tuberous: root thickened by the storage of nutrients, without definite shape.

It is important to mention that napiform and tuberous roots are not the same as the bulbs and tubers, which are modified stems, not roots.

 

 

 

Senaida Ba (FLAAR Mesoamerica) finds Habenaria repens in Yaxha park (Peten, Guatemala).

Posted June 7, 2019

Habenaria repens bog aquatic orchid Savanna 3 Ferns

Click to enlarge Habenaria repens
Left to Right: Jorge Manuel Marcos Martínez (PNYNN, helpful park ranger), Senaida Ba (FLAAR Mesoamerica), Nicholas Hellmuth (FLAAR Mesoamerica), Ricardo Herrera Marroquín (PNYNN, helpful park ranger), and Ericka Garcia (capable and enthusiastic university student at Universidad del Valle de Guatemala).

Senaida is deservedly proud because Nicholas was so focused on the wide-open white flowers of Sagittaria latifolia, which was another plant 3 meters to the left, that he did not notice this orchid in his enthusiasm to reach the other plant. Senaida hiked in separately (while Nicholas was photographing the Sagittaria latifolia plant) and noticed this Habenaria repens orchid. It is known for occurring in wet areas of Peten.

The water here is not part of Lake Yaxha whatsoever; this is the exterior ring of pools of water around the Savanna of 3 Fern Species. On the aerial photographs of IGN, Instituto Geográfico Nacional, you can see non-connected pools of water in an oval pattern around this biodiverse series of mico-ecosystems. To our knowledge we are the first research team to document the plants and this ecosystem.

Enlarged photo info: NIKON D5, lens AF-S VR Micro-Nikkor 105mm f/2.8G IF-ED;
settings: f/3, speed 1/1600, ISO 640.

Several months ago Dr Nicholas (Hellmuth) found an aquatic orchid (Bletia purpurea) in dozens of locations around the edge of Lake Yaxha. While doing research he noticed that Habenaria repens had also been found in bogs and watery areas in several parts of Mesoamerica (including in the Peten area of Guatemala).

So we looked around Lake Yaxha and in other wet areas of the park...but no Habenaria repens. But when the CONAP+IDAEH park administrators assisted us to reach a remote part of Parque Nacional Yaxha Nakum Naranjo, Senaida Ba found Habenaria repens while Dr Nicholas was a few meters away discovering a different bog plant never before documented by any botanist for the Peten area of Guatemala (more on this in a later report of the FLAAR Mesoamerica flora and fauna research team).

This remarkable ecosystem was discovered by Dr Nicholas while analyzing aerial photographs by the Instituto Geografico Nacional (of Guatemala). Every area of the park that has "no forest" is an ecosystem we wish to explore.

And in each of these ecosystems which we have detected from aerial photographs we have found remarkable plants, in most cases plants not well documented by botanists for the adjoining Parque Nacional Tikal.

Although this aquatic orchid is well known for Mesoamerica, to our knowledge no botanist has found it previously in the Parque Nacional Yaxha Nakum Naranjo. Thus we are able to add another plant to the list of what is available to study in this park. We thank the co-administrators of the PNYNN for coordinating our field trip to this remote area of the park. It was a six hour hike back-and-forth, plus a boat ride to the far west end of Lake Yaxha (at which point you have to climb three very steep hills (then climb down them before climbing up the next one).

We also like to do library research (as you can see from our dozens of annotated bibliographies that we post on our FLAAR web sites). But to study plants I would rather hike six hours (after flying to Guatemala, and driving over 1,200 kilometers round trip from Guatemala City to reach the park) and experience the plant and flowers in-person than see a dead wilted, folded specimen in a herbarium.

The park has considerable potential for ecotourism, avitourism (bird watching tourism), and lots of potential for helping local Mayan people learn to protect these ecosystems so they can learn what handicrafts can be made from local plants that can be sold to tourists (obviously not grabbing the plants in the park, but finding the same plants outside the park) and then having training to learn which plants tourists will want to see and experience close up.

99% of orchid specialists with whom I have spoken told me they were not aware of water-related orchids: so the Yaxha park has immediate potential to become a travel destination for all the orchid societies and bromeliad societies in countries around the world.

 


 

Wild Vanilla Orchid Vines found near Yaxha, Peten, Guatemala

Posted June 4, 2019

Every day we are at Parque Nacional Yaxha Nakum Naranjo we find more wild vanilla orchid vines. These wild vanilla orchid vines are common in the bajo type of Peten ecosystem: seasonally very dry; seasonally very wet (sometimes a few centimeters of standing water if it is a very rainy year).

Today (June 4, 2019) we found wild vanilla orchid vines in the bajo vegetation surrounding the Savanna of 3 Fern Species. None were in the sibal-savanna ecosystems; all were outside, growing on the stunted trees in the bajo ecosystem.

This area is uphill from Laguna Lankaja and about 50 meters south of Laguna Perdida (three conjoined lagoons, each one perfectly round).

 


 

Another different species of Passiflora vine flower found in savanna east of Nakum, Peten, Guatemala

Posted May 9, 2019

In Parque Nacional Yaxha Nakum Naranjo, most passion flower vines grow in seasonal bogs or alongside rivers. But park ranger Teco found a Passiflora vine with lots of flowers in a savanna east of Nakum. This savanna has lots of micro ecosystems.

We appreciate the cooperation of the park administration (IDAEH and CONAP) which is what gives us incentive to find plants in this Yaxha park which are not yet documented for adjacent Parque Nacional Tikal.

On Topoxte Island in Lake Yaxha (many kilometers from the Nakum savanna) we found edible Passiflora fruit fallen to the ground from a vine so high in the trees that we had to use a Nikon prime 800mm super-telephoto lens to be able to see and photograph the fruit. These photos we show on www.maya-archaeology.org home page.

We are sending photos to imminent Passiflora-focused botanist Dr John M. MacDougal. We will update this post when we have the species identified.

Field research on Morning Glory Vines & Flowers of Parque Nacional Yaxha Nakum Naranjo

Posted April 17, 2019

In addition to Ipomoea alba, Merremia tuberosa, and Merremia umbellata, we are photographing every single species of the morning glory family Convolvulaceae that we find in Parque Nacional Yaxha Nakum Naranjo, Peten, Guatemala. There are lots of morning glories visible when you take a boat trip around the lake and around the islands and then into Rio Ixtinto.

We have taken enough photographs that we will have three volumes on all these: Vol. I: Ipomoea alba; Vol. II: Merremia tuberosa, and Merremia umbellata, Vol. III: all other morning glory vine flowers. Aniseia martinicensis is one genus we discovered in late March 2019. There are several common purple and lavender morning glory flowers that we will identify and include in the Volume III.

The morning glory popular with Aztec priests and royalty has not been found at the Yaxha park. That is not a research goal but needs to be noted as whether present or absent. No hallucinogenic mushroom is known for Central Peten either: Dr Lowry visited Yaxha when we were there in the 1970’s. We study mushrooms solely for learning which are edible and which produce dye colorant for clothing, paper, and other products. We study morning glory plants to learn which can coagulate latex from Castilla elastica rubber tree and which morning glory plants have other useful aspects.

 


 

Bromeliad flowers, Aechmea tessmanii or Aechmea tillandsioides, Nakum area of Yaxha park

Posted April 10, 2019

Aechmea tessmanii is not listed as occurring in Belize (Balick, Nee, and Atha 2000: 174). Not listed for Peten (Lundell 1937: index for Aechmea, page 223). Surprisingly there is not one single Aechmea species in Cook 2016 on Lacandon Ethnobotany.

The only synonym is Platyaechmea tessmannii, and that is nowhere listed for Peten or Chiapas or Belize that we have yet found (both names will be somewhere, but the main botanical textbooks doe not include Aechmea tessmanii for Peten.

Yet we have found at least two Aechmea at Yaxha area of the park and one in the Nakum area that look very similar. But, Wikipedia says: “This species is native to Ecuador, Peru, and Colombia.” So I kept looking and now estimate that these bromeliads are Aechmea tillandsioides.

Of the family Bromeliaceae we have found lots of Aechmea bracteata; park ranger at Yaxha, Topoxte, and Nakum. Teco showed us two areas filled with Aechmea magdalenae between Yaxha and Nakum and the combined team (IDAEH + CONAP + FLAAR Mesoamerica found another pital of Aechmea magdalenae between El Tigre (Mayan ruins) and the northwestern border of the park. We have located twoz or three other large species of bromeliads; some of which can be either arboreal or terrestrial; some which are almost always found growing out of the gound. Plus there are dozens of smaller bromeliads up in the trees.

Tree found at Yaxha missing from Tree lists of (nearby) Tikal

Posted April 8, 2019

The large savanna found by Hellmuth on aerial photographs has turned out to be a veritable unexpectedly biodiverse area. We have now visited this savanna two times and Elena Siekavizza has a list of about 80% of the trees that grow in the multiple micro ecosystems within this savanna. The savanna is so large we need to return for one more note-taking day (keeping in mind it is a 6-hour round trip hike from the Nakum camp). But the awesome natural beauty, the presence every hundred meters of another micro ecosystem, and the fact that NONE of this specific savanna has been documented by botanists or ecologists (that we know of) previously, fuels our hiking there plus multiple kilometers going from plant to plant in each different ecosystem within the overall savanna.

Yes, a savanna is a grassland, but it does have trees, a few full size (Crescentia cujete and Acoelorrhaphe wrightii). However most other trees are stunted, either because of the permanent water in the bog under the savanna surface and/or because local hunters tend to set fire to the grass every year.

Ximenia americana is known as pepenance (pepe nance) This is because its red fruits (when they ripen and turn orange) remind you of (orange) nance fruits (stunted nance trees are a hallmark of savannas in Peten and adjacent Belize). But Ximenia americana is in the plant family Olaceae, so not a relative of nance from a botanical point of view.

Other local names in Peten include Saaxnic and tocote de monte (Lundell 1937: 120) plus abalche, jocote, and jocote montaña. Local names in Belize include sour plum, Wild plum, or wild lime (Balick, Nee, Atha 2000: 104), who list the fruit as edible. Lundell also says the fruits are edible (1937: 59).

Lundell lists Ximenia americana on pages 45, 59, 96, 118, 120, 135, 137 and 167 (so I am surprised that Schulze and Whitacre do not have it anywhere in their 1999 list of Trees of Tikal). Cook does not list it in her helpful coverage of ethnobotany of the Lacandon Maya of Chiapas.

But surely Ximenia americana will be found at Tikal, but in the meantime, if you are interested in plants of Mesoamerica, the Parque Nacional Yaxha Nakum Naranjo is a great place to visit.

 


 

Ciricote, Siricote or Ziricote, Cordia dodecandra

April 3, 2019

3 dimentional lichen at Yaxha

Camera NIKON D810, lens Nikon AF-Micro-NIKKOR 200mm f/4D IF-ED Macro; settings: f/13, speed 1/250, ISO 1250.

Ciricote, Cordia dodecandra, is a tree found in many areas of Peten and elsewhere in Guatemala (and Mexico, Belize, Honduras, etc.). I have been familiar with ciricote for many decades since its flowers are very photogenic. It blooms in March and April (and other months depending on the climate that particular year).

I call the tree ciricote; gringo botanists tend to spell it siricote; lumber companies spell it ziricote. The species I know best in Guatemala is Cordia dodecandra but many more species exist in Mesoamerica.

In Parque Nacional Yaxha Nakum Naranjo we have found ciricote along the Rio Ixtinto, along the road between Yaxha and Nakum, and next to the camp buildings at Nakum. The Naranjo area should also have plenty of ciricote trees also. The last week of March (2019) I noticed several ciricote trees while hiking through the park.

We will be creating a web page shortly, dedicated to documenting all the uses of different parts of the Cordia dodecandra tree. The Cordia dodecandra tree has the added benefit that if you plant it as a future lumber tree you have fresh fruit every year as the ciricote tree grows. We (FLAAR) know of many properties in Peten where a tree nursery could be started and properties which could be reforested. The nice aspect is this part of Mesoamerica is an original home for the Cordia dodecandra tree, so it is already happy with the climate and soils here.

Since we found several ciricote trees in full bloom during late March every day while in Parque Nacional Yaxha Nakum Naranjo, we would like to show the pretty flowers.
