radicles. Leaves few, large, lanceolate, (broadly so) acumi- 

 nate, plaited or striated, tapering into long, broad petioles, 

 which are sheathed with large, brown, leafy scales, and 

 these again are striated with nerves like the leaves. From 

 the side of one of these tubers arises the large, simple 

 scape, including the flowers two feet long, green, with large, 

 sheathing scales at the joints. Flowers large, handsome, 

 forming a spike at the upper extremity of the scape : each 

 flower having a large bractea at the base, which is oblong, 

 boat-shaped, acute, deciduous, leaving a large scar at the 

 base of the ovary. Sepals and petals large, spreading, 

 nearly two inches long, (the petals narrower), oblong-lan- 

 ceolate, acuminate ; externally pale yellow-brown, within 

 deep chocolate-brown, and striated. Lip large, standing 

 forward : it may be called cucullate, the lower half, or claw, 

 is convolute round the style, so as to conceal it ; the limb is 

 large, three-lobed, the lobes rounded, undulate, the side- 

 ones rose-colour ; the middle one is much the largest, re- 

 curved, subrotund, nerved at the margin, yellowish-white. 

 Spur large, subulato-cylindrical, curved upwards. Column 

 rather short, seinicylindrical, with a large stigma. Anther- 

 case hemispherical, eight-celled. Pollen-masses eight.
