Amboina, Mount Salhoetoe, Teysmann in Hort. Bogor. 
This remarkable plant does not at first sight appear orchidaceous 
at all, on account of its curious habit. I regret that I have been 
unable to find any pollinia in the specimens in my possession which 
might throw some more distinct light on the affinities of the genus. 
The shape of the rostellum argues a long pedicel with a large 
gland ; and from this and other points I imagine it will prove to 
be Vandeous, and probably of the section Sarcantheæ. The 
most noticeable peculiarities in its structure are the singularly 
large tongue-shaped rostellum, the exceedingly small lip, and the 
bristles on the edge of the mouth of the leaf-sheath on the side 
opposite to the lamina. The habit, too, is peculiar, at least in Old- 
World Orchids ; and I do not remember any thing exactly like it. 
With this orchid in Teysmann’s collection were also many 
specimens of Celogyne Rumphii, Lindl., Corymborchis veratri- 
Jolia, Blume, an Eria of the foliosa section, and a species of Bulbo- 
phyllum. The general facies of the Amboinese orchids such as 
are known is Papuan, and very distinct from those of the 
Malayan region.
