40 Materials fm' a Flora of the Malayan Peninsula. 



which Mr. C. B. Clarke, (who elaborated the family of Cucurhitacex for Hooker's 

 Flora of British India, and who kindly compared my Malayan material in the Kevv 

 Herbarium) considers as probably new. But, as these want either flowers or fruit, 

 I am obliged to leave them undescribed. The chief amongst these are Perak, VYray 

 2228 and 3416 ; and Andamans, King's Collector 2200.
