Drooping Leucas is an annual herb which is recognized
by the prominent curved, hairy, ribbed sepal tube of the flowers. Calyx
is about 1 cm long, tubular, prominently curved and almost reflexed in
fruit, hairy in throat, with a somewhat oblique mouth, gland-dotted and
with spreading eglandular hairs; teeth 10, unequal, narrow
linear-lanceshaped, tapering mucronulate, longest teeth up to 2.5 mm.
Flowers are white 1.0-1.2 cm; upper lip short bearded; lower lip
clearly longer than upper. Inflorescence consists os 2-4, distant,
whorled clusters, 1.5-2.5 cm in diameter, relatively lax, about
12-24-flowered. Bracts are narrow ovate-lanceshaped, tapering, equal to
or somewhat shorter than calyces, fringed with hairs on margins. Stems
are erect, 4-25 cm, unbranched or with few lateral branches, leafy,
with spreading firm, eglandular hairs. Leaves are oblong-elliptic,
wedge-shaped, nearly entire to slightly rounded toothed, 4 x 1 cm, with
prostrate long eglandular hairs, gland-dotted; leaf-stalk on lower
leaves up to 1 cm, nearly absent above. Nutlets are narrow oblong,
scarcely trigonous, 2.5 x 1 mm, smooth. Drooping Leucas is found in the
plains of Bangladesh, India, Myanmar, Pakistan and also in the Western
Himalayas. Flowering: August-October.
