Flowers sessile, congested into terminal, or lateral, oblong or ovoid heads, subtended by leaf-like oblong to linear bracts as long as or longer than calyces. Calyx 5-7.5 mm, ± obliquely campanulate, with a spreading or adpressed eglandular indumentum and usually gland-dotted, scarcely bilabiate; tube with some villous hairs internally; teeth of upper lip equal, triangular, those of lower lip triangular-lanceolate somewhat longer than upper.

This is a common (or at least much collected) species in our area. Its variation in stem and calyx indumentum allows three slightly intergrading varieties to be recognized; Rechinger (l.c.), in accordance with his Flora Iranica concepts, gave them subspecific rank. The species also occurs in the SE of the Arabian peninsula.
