a 
retuse end, where it is equally three-lobed, that there is a low transverse trian- 
gular body at the summit of the column, and that the flower is destitute of spots. 
The distinctness of the present species is therefore clearly established, as the 
other species are characterised by the absence of the pair of fleshy arms to the 
column. 
The raceme is very short, the first one produced bore seven flowers, which 
were all turned to one side, though whether this character is constant I cannot 
at present say. The flowers, which are perfectly globular in shape, have the 
sepals and petals light green, which except at the apex are suffused with dull 
purple, and covered throughout with deep dark purple spots. The lip is margined 
and striate underneath with the same colour on a pale ground. This organ is 
always a highly complex organ in this genus, and the following characters may 
be noted. The unguis is very short and broad, and the erect, somewhat decurved 
side lobes about 7 millimetres long, and nearly membranaceous in texture; 
between them, on the base of the mesochile, are two acute plate-like keels which 
terminate suddenly below. The mesochile, to the apex of which the epichile, or 
front lobe, is very delicately hinged, is about equal to the side lobes in length, 
while the epichile itself is somewhat peculiar in shape. Its lower half is about 
8 millimetres broad by the same in length, and thus quite square, while the front 
half is very suddenly dilated into a subcordate-reniforme body, fully 15 millimetres 
across, very obtuse, fleshy and reflexed at the front, but more membranaceous at 
the sides, and with a pair of somewhat curved keels on the very fleshy disc. The 
arms of the column are linear, and about 3 millimetres long. It is a very interes- 
ting addition to the genus.
