Asiatic Wishbone Flower is a creeping to nearly erect
herb, rooting from nodes. Flowers are purple-red to blue-red, 1.5-2.5
cm, protruding from the calyx by 0.4-1 cm. This feature easily
distinguishes it from
Violet Wishbone Flower which
only protrudes out little. Anterior stamens appendages linear, 1-2 mm.
The common name “Wishbone Flower” comes from the two stamens united at the anthers, forming a structure that resembles a chicken wishbone.
Calyx is 0.8-1.5 cm, 1.5-2 cm in fruit, 2-lipped, 5-winged; lips
narrowly triangular, tip tapering, further lobed into 5 small lobes;
wings more than 1 mm wide, decurrent. Flowers arise in leaf-axils,
solitary or in fascicles. Flower-stalks are 0.5-2 cm. Branches are
numerous, long, slender. Leaf-stalks are 2-8 mm, leaf blade
triangular-ovate, narrowly ovate, or ovate-round, 1.5-3.2 x 1-2 cm,
hairless or sparsely hairy, base abruptly constricted and subflat to
broadly wedge-shaped, margin rounded toothed and sawtoothed. Capsule
1-1.3 cm. Seeds yellow, about 0.4 mm. Asiatic Wishbone Flower is found in
mountain slopes, trailsides, shady places, below 1700 m, in NE India, Nepal,
China and parts of SE Asia. Flowering: June-September.
