107. D. stenomeriflora. A curious species occurring 



in the Malay Peninsula, with stamens showing an obvious 



affinity to the genus Stenorneris. The only male plant seen by 



us is preserved in the British Museum of Natural History, 



South Kensington. Another bridge between Dioscorea and 



Stenorneris seems to be found in the climbing species of the 



latter genus described by Taubert in Engl. Bot Jahrb. Beibl.
