| Abstract | |
The present work refers to the taxonomic survey of the genus Begonia L. (Begoniaceae) in Minas Gerais State. This family is comprised of two genera: Hillebrandia Oliv., with one species that is endemic to the Hawaiian Islands and the only member of the family native to those islands, and Begonia L. with approximately 1,400 species of herbs and subshrubs that are widely distributed in tropics and subtropics. Most species of the genus Begonia have ornamental potential with showy leaves, frequently variegated and many species are cultivated in Brazil for this purpose. The native Brazilian species (240 - estimated figure) is concentrated on the Atlantic Forest, being Amazonian species rare. According to the survey, there are 31 species of the Begoniaceae in Minas Gerais State, growing up preferably near water, on the moist places, above or among rocks. The study was based on bibliographic review, consults to herbaria, collections and fields observation. Descriptions, illustrations, geographical distribution maps and comments are also presented about each species. (AU) | |
