Hab. Singapore: Toas district; one plant! 
Johore: Kota Tinggi; one plant ! 
This is a very rare and curious plant, and in many respects 
so utterly different from typical Sarcochili that I am doubtful 
whether it should not be considered as the type of a new genus. 
It has a tall stout stem like that of a Saccolabium, ashort stout 
erect raceme of firm-textured flowers which open one or two at 
a time, but without any long interval. The flowers are yellow 
and brown, inserted from the normal position of orchids so that 
the spur points upwards. The lateral sepals are adnate to the 
back of the lip, which latter has the regular shoe-shape of the 
genus. The pollinia have the double pedicel of several of the 
Sarcanthew—a short pedicel attached to a longer one at right 
angles to it (in the first position). I have only twice met with 
it: once on a tree in Western Singapore, and once I gathered 
it on the banks of a tidal river in Southern Johore.
