above, but often much paler; grey -green and keeled beneath. Scape 

 12 — 15 inches high, one- (sometimes two-) flowered, bibracteate, the dorsal 

 bract one-third the length of the ovary, the ventral one much shorter. 

 Flowers among the largest in the genus ; upper sepal broadly cordate, 

 2-| — 3 inches broad, folded at the mid-vein and undulate in the apical 

 half, white with numerous alternately longer and shorter veins that are 

 green at the base and deep vinous purple upwards ; lower sepal much 

 smaller, lanceolate, acute, white with pale green veins ; petals ligulate, 

 spreading, slightly deflexed, pale green tinted with pale rose-purple 

 towards the apex, margins ciliate with 4— -5 blackish warts on the 

 superior one ; lip helmet-shaped, brown-purple, greenish beneath, the in- 

 folded lobes spotted with deep purple. Staminode horseshoe-shaped, 

 with a deep cleft in the back margin, the two lobes terminating in 

 cusps in front, between which is a projecting tooth.

A recent addition to the genus that was discovered by M. 

 Alexandre Kegnier, of Paris, in Siam or Cochin China, and 

 introduced by him in 1885, but nothing has yet been divulged 

 respecting the locality in which this species grows or its environment 

 there. Its enormous upper sepal renders it remarkable among 

 Cypripedes, even when it is compared with that of Cypripedium 

 Lawrenceanum ; as a species it is intermediate between the last named 

 and 0. barbatum, from which its larger flowers, and especially its 

 broader upper sepal and petals, chiefly distinguish it. 0. callosum 

 usually flowers in February and March. 



0. ciliolare. 



Leaves narrowly oblong or elliptic-oblong, obtuse, 6 or more inches 

 long, tesselated with deep and pale green. Scapes 12 — 15 inches high, 

 one-flowered. Bract small, about one-third the length of the ovary. 

 Flowers 4 inches across vertically; upper sepal broadly ovate, acuminate, 

 ciliolate at the margin, purple at the base, the remainder white ; 

 veins close set, alternately longer and shorter, the shorter ones the 

 narrowest, green, but sometimes purple towards the lateral margins ; 

 lower sepal much smaller, ovate, acuminate, whitish with green veins; 

 petals ligulate, deflexed and recurved, margined with long black hairs, 

 the basal portion green, densely spotted with blackish warts to two- 

 thirds of the length, the apical portion pale purple ; lip prominent, 

 helmet-shaped, dull purplish brown, the infolded lobes pale yellow- 

 green spotted with purple warts. Staminode reniform, greenish stained 

 with pale rose, with a notch in the basal edge, obscurely five-toothed on 

 the distal margin.
