§ 3. Vexillata, Bolus,in Journal of Linn. Soc., vol. xx. (1884) p. 479. 
—Odd sepal posticous, nearly flat, concave or slightly saccate, erect. 
Petals inarched, subexserted. Lip narrow, or rarely broad. Rostellum 
high, erect, protruded or reflexed, the arms usually divaricate, 
produced behind into a petaloid appendage embracing the anther.

lax racemes, or capitate-corymbose ; leaves radical, herbaceous, con- 
temporary with the flowers. Species 21 to 24. 
§ 4. Coryphea, Lindley, Gen. & Sp. Orch, (1838), p. 850. — Odd 
sepal posticous, galeate or subgaleate, erect, with a finely-tapering 
spur. Petals more or less exserted. Rostellum very low. Glands of 
the pollinia 2.—Slender plants with subcorymbose, large or small, 
flowers; membranous, often large, bracts; leaves herbaceous, con- 
temporary with the flowers or (in D. Harveiana) withering early. 
Species 25 to 27.

p. 858. — Odd sepal posticous, erect, subgaleate, the upper part 
flattened and sometimes reflexed, obtusely spurred at base. Petals 
more or less exserted; lip dilated in the middle, mostly with a long
