Abstract

ResumoO Parque Nacional da Serra da Canastra está localizado na porção sudoeste do estado de Minas Gerais, Região Sudeste do Brasil. Na área, Chrysobalanaceae está representada por Couepia grandiflora, Hirtella glandulosa, H. gracilipes, Licania humilis e Parinari obtusifolia. O tratamento da família para o Parque apresenta chave de identificação, descrições, ilustrações, dados de distribuição geográfica e comentários sobre as espécies. Palavras-chave: campo rupestre, cerrado, florística, unidades de conservação. AbstractSerra da Canastra National Park is located in southwestern Minas Gerais, Southeast Brazil. In the Park, Chrysobalanaceae is represented by Couepia grandiflora, Hirtella glandulosa, H. gracilipes, Licania humilis, and Parinari obtusifolia. A key to the species, descriptions, illustrations, distribution data, and comments about the taxa are provided.

Comparative leaf morphological analysis of 20 species of Chrysobalanaceae

“…aperta is the only species with the same color on both sides of the lamina. This feature is not associated with a particular genus, as it was reported by Hemsing and Romero (2010) in Hirtella gracilipes and Licania humilis. No exclusive characters were observed for any genus, probably due to the low number of species per genus analyzed in this study.…”

“…The species of the family have a relatively uniform external morphology (Yakandawala et al 2010) with simple, alternate, entire, glabrous leaves (sometimes with indumentum on the abaxial surface), two glands at the base of the blade or on the petiole, two stipules, and ant-domatia are often present (Prance 1972). Species of this family are used for timber, food, and for tree planting and landscaping (Prance and Sothers 1999;Lorenzi 2002); some have medicinal properties (Carvalho and Costa 2009) Taxonomic studies with Chrysobalanaceae are usually based on floral morphological traits (Prance 1972;El Ottra et al 2008;Hemsing and Romero 2010). However, morphological studies focusing on vegetative traits are useful in identifying species when fertile material is not available (Cutler et al 2011).…”

“…Floristic studies carried out over the last 15 years in this part of Minas Gerais state (Nakajima & Semir 2001;Romero & Martins 2002;Farinaccio & Mello-Silva 2004;Scudler 2004;Pontes & Mello-Silva 2005;Filardi et al 2007;Carvalho-Silva & Guimarães 2009;Hemsing & Romero 2010;Morokawa et al 2013), suggest that the region has a high number of endemic species from different families of Angiosperms (Romero & Goldenberg 1999;Romero & Nakajima 1999;Assis 2002;Romero & Guimarães 2005;Cavalcanti 2007;Batista & Bianchetti 2010;Chautems et al 2010;Feres 2010;Dutra & Garcia 2013;Farinaccio 2013). Melastomataceae is considered one of the most representative families in campos rupestres of this region with more than a hundred species (Romero & Martins 2002;Silva & Romero 2008), from which at least five are endemic (Romero & Goldenberg 1999, Romero 2000, Romero & Guimarães 2005.…”
