foots biennial, paired, tuberous; daughter-tuber ellipsoid or oblong, 6—14 mm. long, 
5—8 mm. thick, bearing few filiform root-fibres, externally dark brown, fracture white, 
farinaceous, taste somewhat bitter (pure), not followed by any tingling or burning 
Sensation, cambium continuous, forming a slightly sinuous ring in cross-section, 
sometimes with a small inner eambium ring; mother-tuber similar, more ог less 
shrunk at the time of flowering. Jnnovation-bud conical, about 5 mm. long, scales decay- 
ing after sprouting. Stem erect, up to 6 dm. high, simple or sparingly ^ branched, 
often angular from raised lines decurrent from the leaf bases, adpressedly pubescent 
with mostly deflexed curved hairs. Leaves scattered, 4— 7, lowest often decayed at the 
time of flowering or, if present, like those above them, remcte, petioled; petioles 
slender, up to %0 cm. long, gradually decreasing upwards; blades sparsely pubescent 
particularly on the nerves below, cordate-ovate or rotundate in outline with a wide 
sinus, 1—2 сш. deep, 3—5 em. from the sinus to the lip, rarely longer, 4—7 cm. 
across, rarely broader, 3-partite to # or $, intermediate division rhom boid, 
148—8 cm. broad, inciso-dentate ог laciniate below, lacinie 2-dentate near the 
apex, subacute or apiculate, lateral divisions trapezoid, unequally 2-pertite to 2 
or { otherwise like the intermediate; uppermost leaves smaller and less divided. 
Inflorescence terminal, racemose or subpaniculate, few-flowered, loose, pubescent; lower 
bracts like the preceding leaves, intermediate smaller, less divided, upper lanceolate or 
linear; pedicels erect, lowest up to 3 em. long, the others much shorter; bracteoles 
often foliaceous on the lower pedicels, much reduced to filiform on the upper, near 
to the flower. Sepals whitish or suffused with blue, rarely quite blue, more or less 
pubescent ; uppermost helmet-shaped, helmet very oblique in profile, broad, depressed, | 
15—20 mm. high, 18—23 mm, from the tip to the base, 10—13 mm. broad, slightly con- 
cave or very oblique in front, shortly beaked, claw broad, very short; lateral sepals 
oblique, suborbicular or obovate-orbicular, ciliate, 14—20 mm. long; lower horizontal 
or deflexed, oblong, obtuse, 12—16 mm. long. Nectaries hispidulous, claw curved, up to 
12 mm. long; hood more or less leaning forward, 6 mm. long with a recurved obtuse 
spur. Filaments 8 mm. long, hispidulous in the upper part, winged to or beyond the 
middle, wings suddenly or gradually contracted. Carpels usually 5, sometimes 3, 
conniving, oblong-lanceolate, slightly hairy on the back or glabrous, drying black 
with a whitish bloom. Ро ісі 5 or 3, 1 ог more often imperfect, erect, slightly diver- 
gent in the upper part, linear-oblong, up to 20 шш, long, scarcely 4 mm, wide, glabrous 
or nearly so. Seeds oblong-obpyramidal 3 mm. long, winged along the rhaphe with 
undulate, transverse lamelle, running out towards the back.
