Seed cones solitary or in clusters of 3 or 4; peduncle long, 1-5 cm; bracts in 3-5 pairs or whorls, free, margins prominent, broad, membranous, often erose, becoming red and fleshy at maturity; integument tube ca. 1.5 mm, slightly spirally twisted.

H. Riedl notes that Ephedra lomatolepis has seed cones light brown and dry when mature, with bracts free (as in E. przewalskii), the membranous margins much wider than the herbaceous center. The characters of the male plant described here seem to apply to a taxon other than E. lomatolepis (which is endemic to the Balkhash area of Kazakhstan), possibly even to a new species.
