Mr. C. B. Clarke writes : « there are several Ottelias from Easlern Asia in 

 herb. Kew approaching this, but not named». 



I think it may, beyond doubt, be the 0. japonica; the spécimens .collected 

 agree very well with the description given by Miquel (1. c.) : it differs from 

 0. alismoides (L.) Pers. in the smaller shape, the few-nerved and short 

 stalked leaves, the not-crispale, narrow wing of the spathe etc. (C. H. Oslenfeld). 

 Growing in water at Nong Koh Tomyae (No. 57); flowers white. 



Nota. The same species has also been collected by Dr. Jolis. Schmidt in the 

 island of Koh Chang, Gulf of Siam.
