Bombacoideae, Byttnerioideae, Grewioideae and Helicterioideae (Malvaceae s.l.) in the Raso da Catarina Ecoregion, Bahia, Brazil

Abstract

This work presents a floristic survey of the subfamilies Bombacoideae, Byttnerioideae, Grewioideae and Helicterioideae (Malvaceae s.l.) in the Raso da Catarina Ecoregion (RCE), Bahia, Brazil. The samples analyzed were collected from September 2013 to May 2015. The analyses were supplemented with dried collections kept in the herbaria: ALCB, HRB, HUEFS, HUNEB, HST, IPA, PEUFR, R and RB. The identifications were based mainly on specialized bibliographies, protologues, types and herbaria collections. Ten genera and 22 species of the subfamilies were recorded, nine endemic to Brazil. Waltheria L. was the most representative genus with five species, followed by Ceiba Mill. and Melochia L. with three species each, Helicteres L., Luehea Willd., Pachira Aubl. and Pseudobombax Dugand presented two species each and other genera were represented by one species each. Among the species recorded, Luehea candicans Mart. represents a new record for the Caatinga biome. The species most commonly found in the study area were Helicteres velutina K.Schum., Melochia tomentosa L., Waltheria brachypetala Turcz., W. indica L. and W. rotundifolia Schrank. The taxonomic treatment includes identification key, descriptions, illustrations, photos, geographical distribution, reproductive phenology and comments about all studied species. Keywords: biodiversity, Caatinga, morphology, semiarid, taxonomy.

Systematics, Phytochemistry, Biological Activities and Health Promoting Effects of the Plants from the Subfamily Bombacoideae (Family Malvaceae)

“…Recently, morphological, anatomical, palynological, phytochemical, and molecular phylogenetic analyses have shown that separation of Bombacaceae from its related groups viz. Malvaceae, Tiliaceae, and Sterculiaceae is inconsistent [ 5 ]. This plant group includes several plants, which are used for medicinal and economic utilities.…”

New record of Corchorus hirtus L. in Piauí, Brazil

“…The species was processed according to usual botanical techniques (Mori, Silva & Lisboa, 1989), identified based on a specialized literature review (Tschá, Sales & Esteves, 2002;Colmenero-Robles et al, 2010;Lima, Bovini & Conceicao, 2019) For the descriptions of general morphological characters, specialized bibliographies were consulted (Colmenero-Robles et al, 2010;Lima et al, 2019) and complemented with information on the analysis of botanical material, exclusive characteristics species, geographic distribution, flowering and fruiting periods, obtained from online data networks Flora do Brasil 2020 (http://floradobrasil.jbrj.gov.br/reflora/), Tropicos.org (http://www.tropicos.org), Species Link (http://www.splink.org.br/). The exsiccate of the new record was incorporated into the Delta do Parnaíba Herbarium (HDELTA6603), from the Universidade Federal do Delta do Parnaíba (UFDPar).…”
