e specimens which I have seen of this are in a very bad state, 
but I have been aided in the description by a drawing lent me by 
Mr. Curtis, late Superintendent of the Botanic Gardens, Penang, of 
a specimen which flowered in that garden in June, 1896. The leaves 
are of a remarkably soft texture, apparently not succulent, in 
which the very delicate nerves are with difficulty detected. This 
peculiarity, so obvious in dried specimens, is well seen in Mr. Curtis’ 
drawing of the living plant.
