Summary Chromosome counts were carried out in root tip cells of Nesphostylis bracteata (Fabaceae), an endemic legume of Western Ghats, India. A diploid number of 2n =20 is reported here for the first time. The karyotype was found to be symmetrical with all chromosomes having a median region centromere. The chromosome length ranged from 1.50 to 2.69 µm.
A new aquatic species, Rotala sahyadrica S. P. Gaikwad, Sardesai et S. R. Yadav sp. nov. collected from a fresh water lake on a high altitude lateritic plateau ecosystem of the Western Ghats, India is described and illustrated here. It is similar to R. tenella (Guill. & Perr.) Hiern but differs in having cleistogamous and chasmogamous flowers, nectary glands on calyx tube and 8–12 multi‐cellular black trichomes in the axils of bracteoles.
The new species Sida pradeepiana is described from the Idukki district of Kerala state, India. It resembles S. alnifolia and S. rhomboidea, but differs by its concolorous‐rhomboid leaves, unarticulated pedicels, mericarp apex beaked with a single muticous process and stellate pubescent mericarps and hilum of the seeds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
