This remarkable species would be referable to Dr. Blume's Pedilonum 
if that genus were adopted. It has flowered in the Garden of the Horti- 
cultural Society, where I examined it. The structure of its stigma is high 
curious, and unlike that of any other Orchideous plant with which I am 
acquainted. That part which Richard calls the rostellum, and through 
which impregnation takes effect is a two-lipped process, the lower lip ? 
which is thick and abruptly truncate, the upper thinner, very irritable, 
inflected when the pollen is humid, but curving back with considerable 
elasticity if afterwards touched. The whole of the orifice of the stigmatit 
canal is choked up with a thick mucus. 
I am not sure that this remarkable ceconomy is not sufficient to com 
stitute a particular genus ; but I am unwilling to make use of it, especially 
as it is an obscure character, unless it shall be found that a similar strut- 
ture exists in other species which can be combined with it.
