Ephedra californica is a spindly
shrub made up of twigs which are greenish when new and age to a yellowish-gray color and have fine longitudinal grooves on their surfaces. The bark becomes gray-brown, and irregularly fissured and cracked. It grows in height, with similar spread. The tiny leaves grow at nodes on the twigs and dry in drought, to crumble away to leave brownish ridges there. Male plants produce clumps of pollen cones at the nodes and female plants produce egg-shaped seed cones each about long, May to June. ==Native American uses==
