INDIAN MEDICINAL PLANTS. 
the Larger tangentially flattened to horse-shoe-shaped ; mother- 
tubers, vvitli often numerous root-fibres much shrunk, grooved 
and wrinkled with conical stumps (root-fibre bases), collapsed. 
Innovation-bud a much depressed, broad, obtuse cone or hemi- 
sphere, scaled broad with a clasping base usually decaying after 
sprouting. Stem erect, several feet high, straight, robust, simple, 
terete, delicately pubescent in the upper part, otherwise usually 
quite glabrous. Leaves scattered, 6-10, the lowest decayed at the 
time of flowering, intermediate and upper leaves rather distant, 
pubescent when young, at length glabrous, with the exception of 
the nerves below, lower petioles up to 7'5 cm. long, intermediate 
and upper much shorter, somewhat dilated at the base ; blades 
dark-green above, paler below, orbicular or ovate-cordate or sub- 
reniform, with narrow or wide sinus, 1-2 cm. deep, 7-9 cm. from 
the sinus to the tip, 10-12 cm. across, 3-partite to ■£, intermediate 
division rhomboid-ovate from a broad cuneate base, 3-lobed to the 
middle, middle lobe much larger than the lateral, lateral 
divisions trapezoid, very unequally 2-lobed to the middle, all the 
lobps coarsely inciso-crenate or dentate, crense, spiculate or acute. 
I n florescence straight, racemose narrow, up to 30 cm. long, many- 
flowered, rather dense, yellowish-tomentellous, and slightly 
viscous ; lowest bracts resembling the preceding leaves, follow- 
ing ovate or lanceolate, inciso-dentate, or dentate, uppermost 
often entire ; pedicels erect or the lower ascending, lowest up to 
5 cm., upper 2 5 cm. long ; bracteoles, if any, inciso-dentate, or 
dentate, small. Sepils blue, pubescent; uppermost helmet- 
shaped, helmet oblique, sub-semi-orbicular in profile, slightly 
concave in front and shortly beaked, about 20 mm. high and 20 
min from tip to base, 10-13 mm. wide, very shortly and broadly 
cljuved, lateral 6epals sub-oblique or orbicular or slightly 
broader I ban long, up to 16 mm. long, obscuiely clawed ; lower 
sepals elliptic or broad-oblong, obtuse, 12-14 mm. long. Nectaries 
glabrous, clarV erect, or slightly curved, 12-13 mm. long; hood 
leaning forward, rather crenulate. Filaments hispidulous in 
the upper part or almost glabrous, 6 mm. long, broadly winged 
to beyond the middle, wings gradually or abruptly running out. 
Carpels 5, oblong, yellowish-tomentose, conniving in the flower, 
then slightly divergent. Follicles oblong, slightly divergent
