Salix ichnostachya Lindl. ex Andersson belonging to the family Salicaceae is endemic to southern India. Taxonomically this species has variously been treated from time to time due to its apparent similarity with S. tetrasperma Roxb. in certain characters. So far this species has been reported from Tamil Nadu, Karnataka and Assam (?) only. Present study has confirmed that the distribution is extended up to Kerala based on a specimen that was earlier mistreated as S. tetrasperma. The distinct characters of the species are discussed in detail along with illustration and special note on distribution for easy and effective determination.

Sonerila veldkampiana, a new species of Melastomataceae collected from an exposed, high-elevation rocky grassland in Kerala, India is described and illustrated. It resembles S. rotundifolia, but differs in having several important characters like pilose leaf-lamina, terete and glabrous peduncle, inflorescence with 10-35 flowers in branched or unbranched scorpioid cymes, an obscurely ridged hypanthium, long acuminate anthers with a deeply cordate base, and seeds with a sub-excurrent raphe. © 2013 Magnolia Press.

Antibacterial activity of cold water and ethanolic crude extracts of leaves of Strophanthus wightianus Wall. ex Wight was evaluated against Gram negative bacteria(Escherichia coli, Pseudomonas fluorescens, Klebsiella pneumoniae and Enterobacter aerogenes) and Gram positive bacteria (Staphylococcus aureus, Methicillin resistant Staphylococcus aureus, Streptococcus mutans and Bacillus subtilis). Methicillin resistant Staphylococcus aureus was the most sensitive strain of those tested with the cold water extract and Enterobacter aerogenes with the ethanolic extract of leaves Strophanthus wightianus Wall. ex Wight. Qualitative phytochemical analysis gave positive results for alkaloides, anthraquinones, lipids/fats, glycosides, phenols, carbohydrates, tannins, resins, reducing sugars,saponinsand flavonoids.
