CNPq. RESUMO(O gênero Leandra, seções Carassanae, Chaetodon, Niangae, Oxymeris e Secundiflorae (Melastomataceae) no estado do Paraná) O gênero Leandra pode ser reconhecido pelas folhas destituídas de formicários, inflorescências terminais e/ou pseudo-axilares, pétalas florais com ápice agudo/acuminado e frutos carnosos. Na última revisão do gênero, o mesmo foi dividido em sete seções, reconhecidas com base na posição e tipo da inflorescência, presença e tipo de tricomas e morfologia das sementes. Neste trabalho são apresentadas chave de identificação, descrições, ilustrações e dados sobre a distribuição geográfica das 43 espécies ocorrentes no Paraná, e pertencentes a cinco seções de Leandra: Carassanae, Chaetodon, Niangae, Oxymeris e Secundiflorae. Palavras-chave: taxonomia, flora, Brasil. ABSTRACT(The genus Leandra, sect. Carassanae, Chaetodon, Niangae, Oxymeris e Secundiflorae (Melastomataceae) in the state of Paraná) The genus Leandra can be recognized by the leaf blades without formicaria, terminal and/or pseudo axillary inflorescences, by the acute/acuminate petals and freshy fruits. In the last revision of the genus, its was divided into seven sections, based on inflorescence type and position, presence and type of hairs and seed morphology. Here we present identification keys, descriptions, illustrations and data on geographic distribution for the 43 species from five sections of Leandra occuring in the state of Paraná: Carassanae, Chaetodon, Niangae, Oxymeris , and Secundiflorae.
Two species of Leandra that occur in low montane and montane rain forests in the state of Espírito Santo, Eastern Brazil, are described and illustrated here. Leandra magnipetala can be recognized by the pedicellate flowers, costate hypanthia, and large, broadly lanceolate petals. Leandra triantha can be recognized by the apical, short-peduncled triads, diads or solitary flowers and by the granulose-glandulose, strigose and glandulose-strigose bracts, bracteoles, and hypanthia.
