Penang Hill: near the Waterfall: Selangor: Langat. 
In rocky woods. I have this curious plant in cultiy ation in the 
Botanic Gardens in Singapore. 
Baillon described a species of Synadenium as Huphorbia Syna- 
denia but this has been referred to its genus Synadenium, so that 
the above name will stand. 
CUPULIFERAE. 
Quercus Rassa, Miq. 
On the top of the mountain Gunong Semangkok grow two 
oaks, which are certainly not typical Q. Rassa ut at the same time 
there are in the Singapore herbarium specimens which seem to be 
intermediate forms. The typical QY. Rassa is a tall tree with very 
narrow close veined coriaccous leaves, and this is the plant which 
grows on Penang hill, where it does not vary to any extent. King 
in the Calcutta Annals mentions a variety latifolia which I take 
it is represented by his 6983 from Gunong Hijau in Perak.
