Plate 40. Fig. 1, flower, front view ; 2, odd sepal; 3, one of the 

 side sepals ; 4, a petal, under side ; 5, ditto, upper side, — all the fore- 

 going magnified about 3 diameters; 6, lip, magnified about 10 diams. ; 

 7, column, front view ; 8, one of the pollinia, — the latter figures 

 variously magnified. 



Stem erect terete, somewhat flexuous, distantly leafy, the base 

 enclosed in a long sheath, 15-37 cm. high ; leaves 3, cauline 

 remote oblong-lanceolate acute spreading or ascending, faintly 

 3-nerved, the lowest 6-11 cm. long, the upper gradually smaller; 

 raceme subpyramidal, 3-12-fl., flowers spreading, bracts leaf- like 

 about as long as the ovaries ; side sepals semi-ovate spreading or 

 protruding and deflexed, about 1 cm. long ; odd sepal (together 

 with the petals) galeate funnel-shaped acuminate, tapering gra- 

 dually at base into a slender arched spur, 2-2*5 cm. long ; petals 

 oblong, as long as the mouth of the galea ; lip linear erect, as 

 long as the stigma (scarcely 2 mill.), and closely applied to its 

 front ; rostellum ascending almost vertically above the stigma, 

 the posterior middle lobe rather large ; glands of the pollinia 

 distant ; ovary cylindrical, tapering at base into a short pedicel. 



Described from several living specimens received from Gra- 

 hamstown, and from dried specimens. Colour of the flowers 

 mauve, with dark purple spots on the sepals and petals. A very 

 pretty and distinct species worthy of cultivation. From the 

 elevation it reaches it cannot be tender, and the tabers would 

 probably bear a little frost. Had the genus Disa not already 

 been one of large size and very diverse structure I might have 

 been tempted to follow Eeichenbach in reducing the present 

 to it. But the agglutination of the petals to the odd sepal does 

 not occur in that genus, nor the remarkably small and peculiarly 

 formed lip. The former character and the occasional clinging 

 of the lip to the front of the stigmatic cushion plainly indicate a 

 transition towards Disperis. But the distinction remains pro- 

 found by the peculiar and much more differentiated character of 

 both lip and column in the latter genus.
