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 کاملUsing LC and Hierarchical Cluster Analysis as Tools to Distinguish Timbó Collections into Two Deguelia Species: A Contribution to Chemotaxonomy.
The species Deguelia utilis and Deguelia rufescens var. urucu, popularly known as "timbó," have been used for many years as rotenone sources in insecticide formulations. In this work, a method was developed and validated using a high-performance liquid chromatography-photodiode array (HPLC-PDA) system, and results were analyzed using hierarchical cluster analysis (HCA). By quantifying the major...
متن کاملVigna yadavii (Leguminosae: Papilionoideae), a new species from Western Ghats, India

It is morphologically close to Vignadalzelliana (Kuntze) Verdc. but differs in its underground obligate cleistogamous flowers on positively geotropic branches, hairy calyx, small corolla, linear style beak and dimorphic s...
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...
