Sinopse de miconia ruiz & pav. stricto sensu no estado do Pará, Brasil.

Abstract

Miconia stricto sensu is a megadiverse genus of the family Melastomataceae with 1,196 known species. The Amazon rainforest is the largest center of diversity of the genus, and, in Brazil, it is represented by 288 species, of which 125 are endemic. In the last decades, the genus has not received any comprehensive taxonomic treatment in Brazil. The monographs with this scope, such as Flora Brasiliensis and Monographie Phaneropagamarum, date back more than a century. In Brazil, the studies on the group are concentrated in non Amazonian regions, thus Amazonian species are understudied in the country. The present study aimed to elaborate a synoptic treatment for the species registered in Pará, adding important records of Miconia to the state. Based on the examination of the collections of the herbaria BHCB, FC, HAMAB, HBRA, HCJS, HERBAM, HIFPA, HF, HSTM, IAN, INPA, M, MFS, NY, MG, RB and SP, synthetic descriptions, dichotomous keys, geographic distribution data, phenology, habitat, vernacular names (when present on the labels) and iconography. A total of 84 species were recorded in Pará state. Among these, two are endemic to the state (M. santaremensis and M. secundiflora), one is a new record for Brazil (M. tschudyoides) and three of them presented a wider geographical distribution (M. ceramicarpa, M. ciliata e M. nervosa).
