O gênero Justicia L. (acanthaceae) no Estado do Pará, Brasil.

Abstract

The genus Justicia L. is the most representative in number of species in Acanthaceae, with ca. 600 species, being mentioned 128 for Brazil, distributed in ali regions and phytogeographical domains. Taxonomic studies on Acanthaceae are incipient with Amazonian species, and are limited to a few works. In this perspective, the present taxonomic study, directed to Justicia, increased the collections of the Amazon herbaria and tripled the number of species registered to the State, increasing the knowledge on the distribution of these taxa for the State of Pará, but also for Brazil. The present taxonomic treatment was based on herbarium material from collections of the Amazon herbaria HBRA, HCJS, HSTM, lAN, MFS, MG, and INPA, and extra-Amazonian R, RB, BHCB, SP, and SPF, as well as field expeditions throughout the study, arca and monitoring of cultivated plants. The research resulted in two chapters: in the first "The genus Justicia L. (Acanthaceae) in the State of Pará, Brazil", 28 species are taxonomically treated, with seven new records for the State of Pará; six accepted names of Justicia are lectotipified and proposed a new name, a new species was also published (Annex) and and were six more. Three of them are presented in chapter two "Three New Species of Justicia L. (Acanthaceae) from Brazil" and the remaining three (Justicia sp.l, sp.2 and sp.3) are in the process of compiling and making the data for publication. Three species were not identified (Justicia aff. Cayennensis, Justicia sp. 4 and sp. 5) requiring further studies to confirm their names. In this way the present research contributed to the knowledge of the Amazon and Brazilian Flora
