Abstract

The origin and history of the genus Ephedra has been recently discussed in "Botaničeskij žurnal" by I. T. VASIĽČENKO and the present author. Considering the flower morphology of Ephedra, its recent distribution and palaeography of Eurasia, the author has come to the conclusion that the genus Ephedra originated in Central Asia during tho Cretaceous period and then migrated to N. and S. America and to the Mediterranean.
