摘要

Alysicarpus Necker ex Desvaux (Fabaceae, Desmodieae) consists of 30 species that are distributed in tropical and subtropical regions of the world. In India, the genus is represented by ca. 18 species, of which seven are endemic. Sequences of the nuclear Internal transcribed spacer from 38 accessions representing 16 Indian species were subjected to phylogenetic analyses. The ITS sequence data strongly support the monophyly of the genus Alysicarpus. Analyses revealed four major well-supported clades within Alysicarpus. Ancestral state reconstructions were done for two morphological characters, namely calyx length in relation to pod (macrocalyx and microcalyx) and pod surface ornamentation (transversely rugose and nonrugose). The present study is the first report on molecular systematics of Indian Alysicarpus.
