73. Corysanthes, R. Brown. 
Very small, terrestrial, 1-leaved, 1-flowered herbs. Leaf cordate ог sub-orbicular. 
Flowers large. Sepals unequal; the dorsal large, concave, concealing and arching over 
the column, the Jateral pair filiform. Petals filiform like the lateral sepals, or absent. 
Lip large, erect, convolute round the column, its base usually with two short spurs; its 
. apical lobe free, expanded, and with dentate or fimbriate margins. Column short, erect, 
2-winged at the apex. Anther erect; pollinia oblong, free, or sessile on the rostellum, 
Stigma large. Capsule’ erect, on an elongate pedicel. 
This genus is mainly Australasian ; thirteen species being natives of Australia, New Zealand and 
Samoa, while five are Malayan. The flower is remarkable for the great development of the dorsal sepal, 
the lateral sepals being filiform; the petals also are either very small or, as in the present instance, 
altogether absent. Until the discovery of the species deseribed below, no species of Corysanthes had been 
known to grow farther north than the central mountain range of Perak in the Malay Peninsula.
