Twisted Swallow-Wort is an undershrub growing up to 1
m tall, characterized by striped stems with velvet hairs arranged along
one or two narrow lines. Internodes measure 0.5-10 cm long. Flowers are
borne mostly in stalkless clusters in leaf-axils, ot with velvet-hairy
flower-cluster stalks up to 1.5 cm long. Flowers are small, 4.5-5.5 x
2-3 mm, dark purple, with clockwise-twisted petals densely bearded
inside. Sepals are narrow and fringed with hairs, up to 2 mm. The
corona is triangular-rhomboid and shorter than or equal to the
gynostegium. Leaves are usually opposite, rarely arranged in whorls of
3-4, with short leaf-stalks 2-13 mm long. The leaf blades are narrowly
ovate to lance-shaped-ovate, 3-13 x 1-3.5 cm, discolorous, with pointed
tips and blunt bases. Veins are visible on both surfaces, while the
margins and upper veins bear sparse velvet hairs. Fruits are
spindle-shaped follicles, 4-7.5 x 0.8-1 cm, hairless with faint
striations. Twisted Swallow-Wort is found in W. Pakistan to Kashmir and
Himachal Pradesh, at altitudes of 750-2800 m. Flowering:
