ANATOMIA COMPARADA DE ESPÉCIES DE Calycophyllum DC. (Rubiaceae)

Autoria SCIMAGO INSTITUTIONS RANKINGS

RESUMO

São anatomicamente descritos os lenhos de três espécies e uma forma botânica do gênero Calycophyllum DC. (C. candidissimum, C. multiflorum, C. spruceanum e C. spruceanum f. brasiliensis), de acordo com IAWA (1989). A maior parte das características observadas concorda com o padrão típico em Rubiaceae, permitindo agrupá-las na estrutura de lenho "Tipo II": poros predominantemente em múltiplos radiais; parênquima axial ausente; raios grandes (2-4 células ou mais), com poucas camadas de células quadradas e eretas nas margens; e fibras septadas, com pontoações simples. Os caracteres, observados nas quatro espécies, discordam do padrão anatômico da subfamília Ixoroideae.

Palavras-chave:
Anatomia da Madeira; Análise de agrupamento; Ixoroideae
