224 MR. HENRY RIDLEY ON ORCHIDEH AND 
peninsula. It is a terrestrial plant. There are two forms; the 
commonest here being the one with purple flowers (the var. 
fusca= Dienia fusca, Lind].), which grows in the damper woods ; 
while the other, with green or greenish yellow flowers, grows 
in drier spots. 
It is commonly self-fertilized, the pollinia falling out of the 
anther upon the stigina over the edge of the very small 
rostellum. It almost invariably fruits, hardly a flower failing 
to set, and, like Spathoglottis plicata, Blume, and Spiranthes 
australis, Lind]., both self-fertilized plants, it is very widely 
distributed, occurring in Northern India, Burmah, Siam, 
Andaman Islands, China, Java, and Northern Australia. The 
natives in Malacca call it “‘ Siqundol Hutan.”

A very beautiful plant, but by no means common.

Perhaps not distinct from L. nervosa, Lindl.

In the genera and species of Orchidaceous plants Lindley 
described, as three distinct plants, Empusa paradova, based on 
specimens collected by Wallich in Northern India; L. odorata, 
based on a figure by Rheede in the Hortus Malabaricus, and 
L. nervosa, based on figures by Reeves and Thunberg. The first 
two have long since been recognised as belonging to the same 
species, a very widely distributed one. But LL. nervosa I 
thought better to keep separate (see my monograph of [paris 
in ‘Journ. Linn. Soc.’ (Bot.), xxii. (1886) 262), on the ground 
that it was quite distinct in colour, being purple flowered
