fl. Dec.; not common. Bolus, 4638; Zeyher (no station), 1579; Herb. Norm.

The colouring is very peculiar. The side sepals are divided in 
this respect longitudinally into two parts, the anterior half being 
white, the posterior half black-purple on the outer or lower side, deep 
crimson on the upper; the hood greenish white and veined; the petals 
and lip pale green variously mottled with purple. Resembles D. mela- 
leuca, with which it has been frequently confused in herbaria; in 
Linneus’s own herbarium, now in possession of the Linnean Society, 
it is so mixed. Dried specimens are often puzzling to distinguish, 
though the habit is a little different. But the colouring is so strikingly 
different that there is no possibility of confusing them in the living 
state. It is a much less common plant than D. melaleuca, with 
which also it frequently grows intermixed.

apiculate, about 4 in. long; odd sepal cuneate or nearly obcordate, 
with a short conical pendulous spur inflated at the mouth and suddenly 
contracted and tapering below, the whole about 10 lines long; lip 
broadly elliptical, about as long as the sepals; all the foregoing 
expanded and spreading horizontally; petals very small, ear-like, 
lobed at the apex and the base, lying flat upon the bases of the sepals, 
adnate to the column at base ; rostellum very low, deeply emarginate; 
stigma somewhat excavate, lying upon the square elevated column.
