ABSTRACT - The archipelago of Anavilhanas is located in the bass 
rio Negro, between the municipal districts of Manaus and Novo Airão. 
In the area, igapó vegetation and riverine forests where a rising of 
the species of Leguminosae was made prevails. The collected material 
and identified it was incorporated at INPA herbarium. They were 
related 67 species distributed in the three subfamilies, prevailing 
Fabaceae with 29 species, 21 Caesalpinioideae and 17 Mimosoideae. 
The genera with larger diversity are Swartzia (eight species), 
Dalbergia, Dioclea, Inga, Macrolobium o/íí/ O rmosia, with three species 
each. The disposition taxonomic of the tribes and synonymies of the 
species are approached. Most ofthe found species has arboreal habit, 
still happening species vines and shrubs. The geographical 
distribution was considered, meeting species with occurrence in the 
whole amazon area, some extending to Central America and of the 
South. Another revealed a certain “endemic" degree, they have only 
been registered in Rio Negro, as the macucu ('Aldina heterophyllaj, 
the faveira-branca fCIathrotropis nitidaj and the saboarana ("Swartzia 
sericeaj. In the evaluation of the bio-economic potential ofthe species, 
it was verified that most has in the wood its main economic product, 
and these can supply seeds for future studies, exploration in 
reforestation and recovery of degraded areas. Other species can be 
taken advantage of for production of eatable fruits, natural gums, 
Cork, varnish, laccpier, medicines, ornamental, etc.

INTRODUÇÃO 
A família Leguminosae representa um dos principais c mais 
importantes grupos de plantas dentre as fanerógamas e, 
quantitativamente, esta entre as três maiores famílias botânicas, 
juntamente com a Orchidaceae e a Asteraceae. Mesmo assim, a sua 
extensão, especialmente no que se refere ao número de espécies que 
constitui a família e sua distribuição geográfica, diverge entre os autores: 
Allen & Allcn (1981) estimam a família com 748 gêneros, abrigando
