Easily recognised by the ribbed and rugose seeds and the minute 

 white points (cystoliths) in the leaves. 



Thwaites appears to have distributed to the Paris Herbarium, under 

 C. P. 1 1 83, some fruiting specimens labelled 'C Hcyticana^ These are 

 described by Planch. (1. c. 502) as C Thwaitesii and characterised by 

 having the cymes much shorter than the long petioles, and pale glaucous 

 leaves. I have not seen this.
