Fseudohilbs crowded, of one usually maQj-grooved node, 1—U in. long, sessile or substipitate.
Leaves 1 in., sessile, chanolled along the centre above, strongly keeled beneath,

Lateral sepals 7-uerved. Lip with the median ridge obscurely caruncled, ending in a
horse-shoe-shaped or notchcd cai-uncle in front of the terminal lobes.
The description of this given in Rosbuigh'B Flora is mixed up "with that of an Eria, no doubt
through an error of tlio transcriber or printer; his drawing of it is excellent. Aeoording to the plate here
given, the pseudobulbs are sometimes tetratjuetrons, which suggests the suspicion that D. quadrangulave.
Parish (Fl. Erit. Ind. v. 714), may not be (as Parish supposed it was) really distinct. The flowers are
identical in the two, but D. quadrangulara otherwise difiers in the clavate pseudobulbs, linear-oblong leaves
and fascicled -flowers. Mr. Ridley, writing to mo from Singapore, says that '^D.pimilum is common at
Singapore, with flowers yellow or oream-colouied ; lip with a dark spot at the tip, or veined with red.
I never saw many flowers in a head as in D. qmdrangidure."

Tu the Flora of British India I have described; the flowers from various sources as being as
variable in colour as those of D. denvdans, to which this species is closely allied. I had not, hewever,
any knowledge of these being green ns here represented, and I had not observed the toothing
of the top of the column ; or that the margin of the anther was erose in D. denudans and entire
in D. eriafiorum. The steras also of this are longer and mora slender in the specimens I have
examined than in tho figure here reproduced, which ia inscribed "84., D. denudans, Don? Mr. J
