and Ceylon specimens of Z. Rhetsa, with a few leaves, as Roxburgh describes in Z. 

 Budrunga, which leads me to suspect that Roxburgh may, by snnie mistake, have 

 described a specimen of Z. Rhetsa with few leaflets for one of the Silhet Z. Budrnn<tti. 

 Should this not be so, and should his Budmnga prove really different from 7 

 Wallich's name of Z. crenatum must be given to the plant here described.
