Morphological and micromorphological characteristics of Desmodium fruits (Leguminosae: Papilionoideae).
The genus Desmodium is represented in Santa Catarina State, Brazil, by 13 species, all with lomen- taceous fruits. Shape, size and isthmus margin of loments vary, while the surface is glabrous, or covered by trichomes of different types. Morphological diversity of trichomes becomes particularly relevant to taxonomic description. The trichome types present on the surface of Desmodium fruits prov...
متن کاملFemale gametophyte development in Adesmia latifolia ( Spreng . ) Vog . ( Leguminosae – Papilionoideae )
(Female gametophyte development in Adesmia latifolia (Spreng.) Vog. (Leguminosae – Papilionoideae)). The female gametophyte has a monosporic origin and a Polygonum type development. The female gametophyte growth consumes a large part of the neighboring nucellar cells and, in the micropylar region, part of the nucellar epidermis and internal integument. The mature gametophyte is composed of only...
متن کاملFloral structure and ontogeny of Syndiclis (Lauraceae)
Generic delimitation in the Beilschmiedia group of the Lauraceae remains ambiguous because flowering specimens of a few genera with confined distribution are poorly represented in herbaria, and a few floral characters important for taxonomy are still poorly known. Syndiclis is sporadically distributed in southwestern China, and is represented in the herbaria by only a few flowering specimens. W...
متن کاملPatterns and development of floral asymmetry in Senna (Leguminosae, Cassiinae).
The buzz-pollinated genus Senna (Leguminosae) is outstanding for including species with monosymmetric flowers and species with diverse asymmetric, enantiomorphic (enantiostylous) flowers. To recognize patterns of homology, we dissected the floral symmetry character complex and explored corolla morphology in 60 Senna species and studied floral development of four enantiomorphic species. The asym...
متن کاملA molecular phylogeny of Caraganeae (Leguminosae, Papilionoideae) reveals insights into new generic and infrageneric delimitations
Based on sequence data of nuclear ITS and plastid matK, trnL-F and psbA-trnH markers, the phylogeny of the subtribes Caraganinae and Chesneyinae in tribe Caraganeae was inferred. The results support the monophyly of each of the subtribes. Within subtribes Caraganinae, Calophaca and Halimodendron are herein transferred into Caragana to ensure its generic monophyly. The subtribe Chesneyinae is co...
