This is a species which, though discovered as long ago as 
the beginning of this century, and published by Lindley 
about 1830, has since been misunderstood, partly because 
Wight figured another and closely allied species (D. ch/orops) 
for it; and still later a third plant, a Moulmein one (D. 
Fytcheanum, Batem.), has been figured as D. barbatulum in 
this magazine (Tab. 5444). As it is, the true D. darbatulum 
may be known from D. chlorops by its larger pure white 
flowers, with more elliptic acuminate sepals, and much nar- 
rower petals; and from D. Fytcheanum by the sepals not 
being orbicular, by the totally different lip, and colourless 
column, as also by the swollen base of the stems. A much 
closer ally is the D. Heyneanum (Lindl. in Wall. Cat., 
n. 1995, et Gen. et Sp. Orchid., p. 90; Wight. Tc. t. 909) ; 
but this is a very much more slender plant, with smaller 
flowers, and other differences.
