1989. Anatomy and histochemistry of colleters in Roupelia grata (Apocynaceae). -Nord. J. Bot. 8: 493496. Copenhagen. ISSN 0107-055X. The colleters of Roupelia grata are present on the petiole of the leaf, bract, bracteole and calyx. A mature colleter has a distinct head and a stalk. The parenchymatous central core is surrounded by epithelial cells. The senescence of the colleter occurs at its apex first and then proceeds towards the base.

In the recently published paper-'Liver Injury due to Ashwagandha. A Case Series from Iceland and the US Drug-Induced Liver Injury Network' which illustrated the hepatotoxic potential of Ashwagandha seems to be quiet misleading. 1 We would like to point out some facts for clarification and without which it would simply be a mere assumption.
