This, one of the most Sarai of au and ‘tough probably referable 
to the great tribe of Hedyotiden, is closely allied to no other plant of the 
Order, except perhaps Carlemannia, with which it agrees in its most anoma- 
lous characters of a diandrous flower, absence of stipules, and dentate leaves. 
It ditfers from that genus in the valvate corolla-lobes, and from other Hedy lyo- 
tidee in the ase stigma, and fleshy capsule 5-valved to the base. It is 
named in honour of M. De Silva, one of Dr. Wallich’s most acute and inde- 
fatigable sella, who was the first explorer of the Khasia and Silhet jungles.
