Smooth Catmint is an erect perennial herb, 1-3 ft cm tall, with usually
branched stems. Flowers are blue-purple, borne in dense whorls crowded
into long spikes, 5-10 cm long, at the end of stems. Sometimes there are
one or few widely spaced whorls at the base. Flowers are 8-12 mm, with
the flower-tube much longer than the sepal cup. Upper lip is deeply
2-lobed, lower lip short, rounded. Sepals are linear-lanceshaped
long-pointed, bristly-hairy, as long as the sepal cup. Lower bracts are
ovate, the upper lanceshaped, purplish. Leaves are ovate pointed to
triangular-ovate, usually stalked, 2.5-5 cm long, coarsely
saw-toothed. Smooth Catmint is found on the open slopes of drier areas in
the Himalayas, from Afghanistan to SW China, at altitudes of 2000-4500 m. Flowering: July-October.
