Wildflowers of Southern Arizona
Longleaf Ephedra.
Ephedra trifurca.
Mormon-tea family.
The plants are dioecious. At the stem nodes, the male plants produce 1 or more reddish brown, egg-shaped pollen cones, while the female plants produce 1 or more reddish brown, flower-like seed cones with 6 to 9 whorls of circular, papery, translucent bracts in groups of three. The scale-like leaves are in whorls of three at the stem nodes and will become dry, gray, and shredded with age and can fall off. The stems are slender, rigid, jointed, initially glaucous yellow-green in color, and then aging to yellow and then gray. The base of the plant is woody.
