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.

    Wooded ravines or moist or dry thickets, often planted about dwellings, 500 meters or less; Pete"n; Zacapa; Chiquimula; Baja Verapaz; Jutiapa; Guatemala. Chiapas; Yucatan; British Honduras; Colombia and Venezuela.

    A tree of 18 meters or less with dense spreading crown, the branchlets and petioles minutely puberulent or almost wholly glabrous; leaflets 4, opposite, elliptic to lance-oblong, mostly 5-12 cm. long, petiolulate, obtuse or short-acuminate with a very obtuse tip, acute to obtuse at the base, thinly coriaceous, the nerves and veins not conspicuous beneath; inflorescences axillary, often glomerate at the ends of the branches, usually small and shorter than the leaves, densely tomentulose, the pedicels 1-2 mm. long; flowers white, 3-4 mm. long, the sepals ovate, acute, tomentulose outside; petals ciliate; fruit subglobose, mammillate at the apex, densely and minutely pale-tomentulose.

    Called "tinaljuco" in Honduras. In Salvador there is a belief that the tree fruits only once every ten years, a belief probably without basis. It is said to be much planted in Peten, and to be found about the old ruined cities, as if persisting from former cultivation. The fruit is of a handsome sage-green, or at full maturity yellowish. In the fresh state the rind is firm but flexible, enclosing a considerable amount of dull orange-red pulp that has a slightly acid and agreeable flavor. The fruit is not popular in Central America, because of the competition of so many better ones, but it is sometimes sold in the markets, as at Chiquimula, where it was observed in some quantity in April.

    Note by Hellmuth, we found the fruit ripe on the trees in Izabal in late July.
