Hecatostemon completus is a species of shrub or tree native to northeastern South America and is the only member of the genus Hecatostemon.[1]

Taxonomy

[edit]

Formerly classified in the Flacourtiaceae, phylogenetic analyses based on DNA data indicate that this species, along with its close relatives in Casearia, Samyda, Laetia, and Zuelania, are better placed in a broadly circumscribed Salicaceae.[2]

Description

[edit]

Hecatostemon differs from its close relatives in having numerous stamens in three series and one ring of staminodes, or "disk," inside the stamens.

Distribution and habitat

[edit]

The species is found in tropical deciduous forests, matorrales, savannahs, and even saline flats in northern Brazil, Colombia, Guyana, Peru, and Venezuela.[3]
