Naias graminea var cnigustifolia Rendle (Xaiadacete). In a mono-

 Gardens Lake to be this new variety of N. graminea, 



Rottboellia exaltata L. (Granu'iiece). A weed in the Economic 

 Gardens probably introduced accidentally. 



Trichomanes Motleyi V. D. Bosch. This very curious little fern 

 is abundant on trunks of trees in the Fern valley at Bukit 

 Timah and at Stagmount. It looks more like a hepatic 

 than a fern which is probably the reason for its being 

 often overlooked. It has only been recorded from 

 Borneo.
