Drimys roraimensis is a broadleaf evergreen tree of family Winteraceae. it is native to the tepuis, flat-topped mountains in southern Venezuela and western Guyana. [1]
Drimys roraimensis is endemic to montane cloud forests of the tepuis, where it is found on mountain slopes, along streams, and in swamps between 1,800 and 2,500 meters elevation. [1]
The species' estimated extent of occurrence (EOO) is estimated as 357,372 km2. The estimated area of occupancy is 140 km2, which is likely an under-estimate because of the low number of collections. [1]
A tepui, or tepuy, is a table-top mountain or mesa found in South America, especially in Venezuela and western Guyana. The word tepui means "house of the gods" in the native tongue of the Pemon, the indigenous people who inhabit the Gran Sabana.
Drimys is a genus of about eight species of woody evergreen flowering plants, in the family Winteraceae. The species are native to the Neotropics, ranging from southern Mexico to the southern tip of South America. They are primitive dicots, associated with the humid temperate Antarctic flora of the Southern Hemisphere, which evolved millions of years ago on the ancient supercontinent of Gondwana. Members of the family generally have aromatic bark and leaves, and some are used to extract essential oils.
