Abstract

Herein we present a taxonomic synopsis of Aechmea species from Alagoas, Pernambuco, Paraíba, Rio Grande
do Norte and Ceará states. The lack of a taxonomic key for identification of species, the high rate of endemism
and the recent novelties published within Aechmea from this region motivated this work. Samplings were
conducted in areas of all states studied between 2010 and 2014. We identified 27 species in the study areas
while two names were excluded from the species list compiled from the literature. The subgenus Aechmea
was the most representative with 20 species. Of particular importance was the Gravisia complex, represented
by ten of the 14 species that form this informal taxonomic group. Pernambuco and Alagoas were the most
species-rich compared to the other states. For each species found in the study area, we present identification
keys, comments on the taxonomic relationships, habitat information and geographical distribution.

Key words: Bromeliaceae, Poales, taxonomy, morphology.
