Cornutia obovata


Cornutia obovata, an evergreen tree that can reach 30 meters in height, grows in the limestone hills and lower montane forests of northwestern and central Puerto Rico (USFWS 1987). Its purplish flowers grow in clusters at the end of branch stems.

Only seven individuals are known to exist; two of which are on private land (USFWS 1987). This species inherent rarity, coupled with the effects of deforestation, are the main threats to its existence (USFWS 1987). Other endangered species that share the same forest type with Cornutia obovata are: Epicrates inornatus (the Puerto Rican Boa), Banara vanderbiltii, Ottoschulzia rhodoxylon, Polygala cowelii and Zanthoxylum thomasianum (USFWS 1990). Cornutia obovata was listed as endangered in April of 1988 (USFWS 1988).
