Argyreia lamii, a new species from the Malay Peninsula

Among a number of specimens of Convolvulaceae from the Malay Peninsula sent to me for identification by Mr. J. Sinclair, Singapore, I found a species of Argyreia, which appeared to be new to botanical science. I named it A. lamii in honour of Prof. Dr. H.J. Lam, Director of the Rijksherbarium and Professor of Systematic Botany at the University of Leiden, to whom the present Jubilee-volume of Blumea is dedicated.
