OF ORCHIDS FROM THE EAST INDIES. 341 
could only find two plants; but it was well known to the native 
(a Jaccoon) who accompanied me, as one of the innumerable 
plants used by women medicinally after confinement. 
I am quite unable to suggest any affinity for this plant. That 
it should be classed with Vandeæ appears to me certain from 
the structure of the pollinia, which are, however, rather more 
granular in texture than is usual. The adnation of the petals 
and dorsal sepal and connation of the two lateral petals are re- 
markable; but the singular development of the stelidia is the 
most striking characteristic of the genus. The stelidia are very 
much of the shape of the rib of some animal, with a small pro- 
cess rising from the curved portion corresponding to the tubercle 
of the rib. They curve downwards, and reach nearly to the foot 
of the column, and probably act in some way as guides to the 
insect fertilizer; for the flower is so expanded that some such 
arrangement is required to direct the insect towards the stigma 
and pollen-masses. The lateral lobes of the lip are deflexed, the 
centre being raised, and the minute middle lobe is eurved upwards. 
Although the sepals and petals are inconspicuous and dull in 
colour, the bright violet spot in the centre of the lip and the 
broad white edge make this plant really pretty.
