This text is copyrighted by the Bakers and may not be reproduced without permission.

ORIGIN/HABITAT: Brazil. Plants are found in the mountains in the states of Espírito Santo, Rio de Janeiro, São Paulo, and Minas Gerais. Miller & Warren (1994) reported that this is a common mid-tree species in the Macaé de Cima Forest Reserve in the northeastern part of the state of Rio de Janeiro where they are found in primitive forest up to 4900 ft. (1500 m). They also stated that plants are also found thriving in the leaf litter in areas of forest that are regrowing after being burned. In general, these plants are found in mountain rainforest from 1650-6550 ft. (500-2000 m) elevation and as far as 124 mi. (200 km) from the sea.
