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.

During 2021 and 2022 the team of FLAAR (USA) and FLAAR Mesoamerica (Guatemala) have been focused on finding savannas from satellite images and then figuring out how to find these savannas so we could hike to each one.
Here is an aerial photo by Haniel Lopez from the FLAAR drone DJI Mavic 2 Pro that shows how many savannas are in the southeast part of the Parque Nacional Laguna del Tigre (PNLT). We have found 35 savannas so far (and over 70 savannas a hundred kilometers to the east, outside the PNLT). Our project is 5-years of cooperation and coordination with CONAP for the entire Reserva de la Biosfera Maya (RBM), Peten, Guatemala.

Very close to the Zotz camp you can find a watering hole in the southern part. The aquatic plants that prevail are the Lechuguilla de agua (Pistia stratiotis); Lentejas de agua (Lemna sp.) and (Salvinia sp.) lettuce had a very small white flower.
Everything together creates a very beautiful landscape. On the shore you can see a Zapotón, Pachira aquatica, which we have photographed in large numbers in the Municipality of Livingston, but you can hardly see it in Petén.
At least an hour by car from the first camp of the biotope you can reach the entrance of another of the watering holes of this site, in which if you are lucky you can see crocodiles (Crocodylus moreletii). Then you can go to the Laguna El Palmar, which is a bit complicated to observe, since there is a lot of vegetation growing around it. The team is prepared so we have a ladder which allowed us to have a better view of the place.
According to SIGAP (s.f.) “On the shore of the El Palmar lagoon the oldest occupation was found, where small human groups took advantage of the abundance of natural resources. For more than 900 years they developed their settlement, with an Astronomical Commemoration Complex and a Triadic group, both decorated with masks. In the year 100 A.D. the political headquarters moved to the top of the limestone escarpment, in search of defensive spaces.”

In February we documented species in Río Ixtinto, within the Parque Nacional Yaxha, Nakum y Naranjo. Our main objective was to photograph the blooms of Palo de Tinto or Palo de Campeche (Haematoxylum campechianum). This tree is native to the Yucatan Peninsula in Mexico, Guatemala, and Belize. It was an important source for extracting red, blue and black dyes, but in addition to its dye use, it is also used for restoration, forage, firewood, ornamental planting and it is a honey species (Red de Viveros de Biodiversidad, s.f.).

During the tour we did not find as many flowers as we expected, but it was different from the previous months. On this occasion the weather has been a bit cold and rainy so the River was fuller and wider, we took some pictures with a Drone which allowed us to see that the Río Ixtinto is linked to the Julequito Lagoon in this season.
We saw several birds flying along the river bank like a Kingfisher and two woodpeckers, this was cute and curious on Valentine's Day.

In October we visited Lagunita Creek for the third time during the Documentation of Livingston, Izabal Project. This time the atmosphere was more humid than the last times we have visited it. Therefore, we find various mushrooms on the trails that we want to show you.
As you drive from Guatemala City towards Rio Dulce (en route to Peten) you will see giant mahogany trees all along the highway in El Progresso and Zacapa areas. The mahogany trees are easiest to recognize from October onward when the giant seed pods are visible.
I have been driving this road since the 1970’s. so am familiar with these beautiful trees and their large seed pods (the size of a large pine cone, but smooth).
This week (November 11, 2021), I kept seeing these pods but they were a white color, not the soft brown color of a mature pad that I was used to. So finally I stopped to take some snapshots. Our telephoto lenses were all packed in the back of the vehicle so I had only an iPhone 13 Pro Max available to take snapshots.
We were en route to Rio Dulce, to stay as guests of the owner of Marina and Hotel El Tortegal, along the Rio Dulce south of the highway bridge.

One of our objectives of the October expedition was to photograph the “Espino de Vaca” tree, so we spent one morning walking to the Aldea El Rosario where we could document it.
The next day, in Tapon Creek Reserve, at the edge of the trail we were able to find one again. This tree is important, since it is part of the series of Edible Plants of Wetlands of the Municipality of Livingston, Izabal.
Pithecellobium laceolatum is a species of tree belonging to the FABACEAE family. It lives in tropical and subtropical areas, grows from 0 to 1800 meters above sea level; This species is distributed from the south of the USA, Mexico and Central America. This plant serves to regenerate and improve the quality of the soils because it is associated with other species of the same or other families. It is adapted to survive in climates from very dry to very humid.

In October we visited Lagunita Creek for the third time during the Documentation of Livingston, Izabal Project. This time the atmosphere was more humid than the last times we have visited it. Therefore, we find various mushrooms on the trails that we want to show you.
We invite you to visit Lagunita Creek in Río Sarstún, Izabal to conduct research on flowers and fungi, and you can also do ecotourism.
Fungi have different mutualistic relationships, such as mycorrhizae, which refers to the relationship that exists between fungi and plant roots. On the one side, the roots secrete sugars, amino acids, fatty acids and other organic substances that benefit fungi and, on the other hand, fungi convert the soil minerals and decomposing matter into forms assimilable by the roots of the plant.
There are also endophytic fungi that establish a relationship with the plants where they live within them without causing symptoms. In this case, the fungus is capable of producing bioactive metabolites, as well as modifying the defense mechanisms of its host, allowing and increasing the survival of both organisms.
Fungi classification
Chytridiomycota |
Predominant aquatic fungi, these have flagella and are the most ancestral fungi. |
Glomeromycota |
Fungi that make symbiotic relationships with other organisms such as mycorrhizae. |
Basidiomycota |
They are the most common fungi that we know as mushrooms, they help fix nutrients and degrade organic material in forests. |
Zygomycota |
They inhabit terrestrial foods, a large part of the molds that attack vegetables. |
Ascomycota |
They form lichens, these are associated between fungi with algae, cyanobacteria, yeasts. |

“Labios de mujer” Psychotria poeppigiana is one of the species that we have best photographed during our October 2021 expedition. In Aldea El Rosario, Tapón Creek, there were places where several flowers and fruits of this species were observed.
Psychotria poeppigiana is a species of plant of the RUBIACEAE family. What we commonly see as the red petals of this plant are actually modified leaves or also called bracts. These turn red due to the carotenoid pigments they contain, as a strategy to attract pollinators. The flowers are actually white in color and clustered in the center. When these are pollinated, blue colored fruits can be observed.
Rubiaceae is a family made up of about 600 genera and more than 1000 species of herbaceous, shrubs, trees, vines, epiphytes, which are distributed and of greater diversity in the tropical belt.

In Lagunita Creek area you can find several creeks made by spaces between mangroves, generally you can see a lot of Red Mangrove. It is difficult to navigate in this place, especially if the boat is large and has a roof, like the one we were transporting on this expedition. On this occasion among the Red Mangrove we could see Gray Mangrove, also called Button Mangrove or Buttonwood.
Its fruit is dark red and round. It was important to document this species, since we do not have as many photographs in our digital library.

On the shore of Laguna Yaxha in front of the museum and camp area you can find a dock that is currently covered by water, on the left side there is a Stone Sheet. During our October expedition we were able to observe its spike. We documented it in the afternoon just at sunset, so the light was very good.
Anthurium schlechtendalii is an herbaceous plant belonging to the ARACEAE family. Its common name is pheasant’s tail, or also known as stone leaf (in Spanish). It is native from Guatemala, Belize, Honduras, Mexico (Yucatan peninsula); Nicaragua, humid places of tropical forests from 0 to 15,000 meters above sea level.
Botanical description:
It is a generally epiphytic plant, or in lesser cases lithophytic or terrestrial. It has a stem 3 to 5 cm in diameter, numerous white fleshy roots. Its leaves are supported by a thick, erect, 8-20 cm long petiole, elliptical obovate with wavy margins. The inflorescence is in the shape of a spadix, very characteristic of the Araceae family, supported by a peduncle 35 to 50 cm long. The flowers are 2 mm arranged in a spiral where only those found in the lower part are hermaphrodites. The fruits are oblong berries 1 to 2 cm long, bright red with two seeds. It is a plant that germinates generally by seeds once it has sufficient conditions and falls on organic material rich in nutrients and humid between 26 and 28 degrees centigrade.
