250 MR. HENRY RIDLEY ON ORCHIDEH AND 
The plant is very stout and large for the section, with thick, 
terete, blunt leaves, very distant, on account of the long inter- 
nodes. The flowers are of a thicker texture than most in the 
section, and last longer. They are pure white, except for the 
flame-coloured veins on the inner side of the lateral lobes of 
the lip and the three red keels in the middle. They have a 
scent of heliotrope. The lip is distinctly three-lobed, a rarity 
in the section, the mid-lobe being sharp and acute. 
It is not a common plant.

T have met with nothing corresponding to this species in 
Singapore; but what I take to be the plant intended I received 
from Manilla, sent by Sr. Vidal. If I am correct in this, its 
affinity is with D. crumenatum, Sw., not with the section 
Strongyle, although the leaves are terete, or nearly so.

come from Singapore, but was doubtless erroneously located.

I had some fine plants of this in the Singapore Botanic Garden, 
which I believe came from Mr. G. Mann, in Assam, but their 
label was lost. It has the largest flowers in the section, nearly 
pure white, except a yellow tint on the lip and some pink spots 
on the column foot.
