This plant is chiefly remarkable for the anchylosis of the petals 

 and dorsal sepal, which is so complete that it is almost impossible 

 to trace their point of junction except by the venation. The 

 anther is thrown back very far, so that its dorsal surface is almost 

 at right angles to the top of the ovary. The stigmatic lobes are 

 short, thick, and papillose. The stem is from 12-15 inches high ; 

 the leaves are lanceolate, the lower part tapering into a petiole, 

 the apex terminated by a small cusp.

 Imerina, Ikangosoa, Beans Cowan in Herb. Brit. Mus. ! 

 A weak plant, about 15 inches in height, with two or three 

 flaccid green radical leaves 5 inches long by | inch in diameter, 

 lanceolate and narrowed at the base so as to be almost periolate. 

 The stem bears four or five smaller lanceolate distant leaves passing 

 into bracts, and is terminated by a short raceme of lilac flowers. 

 The lip is broad and more cr less three-lobed ; it is also lilac, but 

 has two oblong dark purple spots in the centre. The spur is re- 

 markable fur being hooked. The ovary is scabrous. 



The colouring is taken from a drawing of Deans Cowan's.
