Bark Anatomy of Arborescent Leguminosae of Cerrado and Gallery Forest of Central Brazil

Abstract: The bark anatomy of28 species of arborescent Leguminosae of 'cerrado' and gallery forest in the Brazilian Federal District was examined. The most significant characteristics for taxonomic purposes were determined to be: delimitation between collapsed and non-collapsed phloem; phloem stratification; type and position of sieve plates; dilatation patterns; arrangement and contents of sc1ereids; and presence of secretory cells. The bark data support the idea that Papilionoideae is the most advanced group of the Le… Show more

“…Papilionoideae is the most advanced group of three subfamilies of Leguminosae (Costa et al, 1997), including some of the largest and most widespread species in the family. It has a variety of vegetation types, ranging from the tropics to deserts and from lowland to montane habitats.…”

“…A placa crivada é geralmente composta em Caesalpinoideae (Costa et al 1997), como o observado em Caesalpinia echinata. Segundo a classificação de Den Outer (1983) para o floema secundário, esta seria do tipo mais primitivo, por serem placas oblíquas e compostas por mais de 10 áreas crivadas.…”

“…Os estudos abordando aspectos do floema realizados no Brasil são mais voltados para aspectos estruturais da casca, descritivos ou relacionados à taxonomia. Dentre estes estudos, podemos citar: Angyalossy Alfonso (1983, que estudou a anatomia da casca de várias espécies de Eucalyptus, com fins taxonômicos; Alves (1996) realizou um estudo descritivo da casca de Cecropia glazioui,; Angyalossy Alfonso & Richter (1991) realizaram estudos da casca de espécies de Buchenavia, com fins taxonômicos para o gênero; várias espécies de Leguminosae foram estudadas por Costa et al (1997); duas espécies de Eugenia foram analisadas a fim de encontrar caracteres diagnósticos para separação entre elas por Soffiatti & Angyalossy Alfonso (1999); e uma análise comparada da casca de raiz e de caule em Stryrax camporum foi apresentada por Machado et al (2005).…”

“…In Aspidosperma, they can appear solitary scattered across the phloem or in clusters. In some lineages, fibers appear in concentric alternating bands, as in Leguminosae (Papilionoideae), Mimosoideae (Figure 4c) [41], Bignoniaceae [20], and Malvaceae, and this is a constant character among them.…”
