Ephedra monosperma

Ephedra monosperma is perennial[4] small shrub that ranges 5 cm to 15 cm high, often with creeping runners. The woody stems are much branched and short, 1–5 cm, and have knotted nodes. Branchlets are spreading and slim usually with slight curved shape. Internodes of branchlets are 1–3 cm long, 1 mm in diameter.

The leaves are opposite, basal 1/3–2/3 connate their length. There is one ovule in each cone that is enclosed by two pairs of cone bracts.[5] Pollen cones, consist of three or four pairs of decussate scales with broad margin, are oblong-spherical shaped, sessile or subsessile at nodes and paired or rarely solitary.[4][6]

Bracts of pollen cones are in two to four pairs, 1/2 connate their length. It pollinates in June, has matured seeds in August,[2] and flowers from May.[4] Seed cones are solitary or opposite at nodes, sessile, and ovoid at maturity.[2] The mature cones are fleshy, red, and glucose, 6–9 mm long, 5–8 mm across.[6]

Ephedra monosperma is found growing in crevices of limestone, cliffs, and rocky slopes, sometimes on the rocks on slope of river valleys often with sparse Juniperus and shrub vegetation. It is also often found in dry pine forests.[4]

E. monosperma is mainly distributed in these Asian locations: Afghanistan, China (Beijing, Chongqing, Gansu, Guizhou, Hebei, Hubei, Nei Monggol, Ningxia, Qinghai, Shandong, Shanxi, Sichuan, Tianjin, Xinjiang, and Yunnan[4]) Tibet, Kazakhstan, Mongolia, Pakistan, and Russia (Buryatiya, Chita, Irkutsk, Krasnoyarsk, Tuva, and Yakutiya[4]).[2]
