Abstract– Section Ceratotropis of subgenus Ceratotropis of the genus Vigna Savi in India, along with comparison of selected characters and an artificial key to the species of the section is given. A new species of Vigna belonging to the section from northern Western Ghats is described and illustrated. In addition, V. mungo var. silvestris is raised to species level.

Abstract– Vigna trilobata (L.) Verdc. var. pusilla Naik & Pokle is elevated to the rank of species and a new name, viz., V. indica T.M. Dixit, K.V. Bhat & S.R. Yadav is proposed based on critical field and herbarium studies. An amplified description of taxon is provided. A comparison of selected characters that distinguish closely related species belonging to section Aconitifoliae is given along with a taxonomic key for identification of species.
Diversity and genetic resources of wild Vigna species in India by I. S. Bisht, K. V. Bhat, S. Lakhanpaul, M. Latha, P. K. Jayan, B. K. Biswas, A. K. Singh-
Abstract-Genetic Resources and Crop Evolution February 2005, Volume 52, Issue 1, pp 53-68- Diversity in morphological characters of 206 accessions of 14 wild Vigna species from India was assessed. Of these, 12 species belonged to Asian Vigna in the subgenus Ceratotropis and two were V. vexillata and V. pilosa belonging to subgenus Plectotropis and Dolichovigna, respectively. Data on 71 morphological traits, both qualitative and quantitative, were recorded. Data on 45 qualitative and quantitative traits exhibiting higher variation were subjected to multivariate analysis for establishing species relationships and assessing the pattern of intraspecific variation. Of the three easily distinguishable groups in the subgenus Ceratotropis, all the species in mungo-radiata group, except V. khandalensis, viz. V. radiata var. sublobata, V. radiata var. setulosa, V. mungo var. silvestris and V. hainiana showed greater homology in vegetative morphology and growth habit. The species, however, differed in other plant, flower, pod and seed characteristics. Within species variation was higher in V. mungo var. silvestris populations and three distinct clusters could be identified in multivariate analysis. V. umbellata showed more similarity to V. dalzelliana than V. bourneae and V. minima in the angularis-umbellata (azuki bean) group. Within species variations was higher in V. umbellata than other species in the group. In the aconitifolia-trilobata (mothbean), V. trilobata populations, were more diverse than V. aconitifolia. The cultigens of the conspecific wild species were more robust in growth, with large vegetative parts and often of erect growth with three- to five-fold increase in seed size and seed weight, except V. aconitifolia, which has still retained the wild type morphology to a greater extent. More intensive collection, characterisation and conservation of species diversity and intraspecific variations, particularly of the close wild relatives of Asian Vigna with valuable characters such as resistance to biotic/abiotic stresses, more number of pod bearing clusters per plant etc. assumes great priority in crop improvement programmes.

I have updated eFI (efloraofindia) page on Vigna (Pl. click).
Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links as far as possible. It’s quite possible that there may be some discrepancy in the accepted names & synonyms taken from other links.
Species discussed so far in efloraofindia are given at the bottom of the page in the form of links against Subpages. On clicking them one can see all the details.
If someone can provide complete list of Indian species with source references it will be wonderful.
Any comments/ corrections are welcome.

Pl. go through Vigna page with images of species (done by …) in efloraofindia.
If you find any mis-identification, pl. let us know.
If anybody can send images of other species of this genera (for incorporation in the website), it will be really nice. Also, if anybody is interested to take up the activity of inserting images on efloraofindia pages from efloraofindia posts, pl. let me know.

Thank you for compilation. I am happy when i seen this page. It is valuable contribution to make easier identification, every person can identify all species of Vigna by this page.
