Abstract: A new species, Ephedra rituensis Y. Yang, D. Z. Fu & G. Zhu, is described and illustrated. This species is similar to Ephedra intermedia Schrenk & C. A. Meyer in having bi- or tri-ovulate cones, and to E. saxatilis Royle ex Florin in having strong and well-developed woody stems and branchlets. It differs from E. intermedia mainly by the shorter micropylar tube straight or slightly curved and the less connate bracts of the uppermost whorl of female cones, and from E. saxatilis by the longer micropylar tube, the bi- or tri-ovulate female cones, more pairs or whorls of bracts, and the smaller seeds. The new species should be ascribed to Ephedra sect. Pseudobaccatae Stapf since its female cones bear fleshy bracts at maturity.
