first=]"Ephedra trifurca" is a species of "Ephedra" known by the common names longleaf jointfir and Mexican tea. It is native to many of the northern states of Mexico and the southwestern United States, where it is a resident of desert scrub plant communities. This sprawling shrub may approach two meters in height. It is made up of erect, sharp-pointed twigs which are light green when young and age to yellowish or greenish gray. It has curling, pointed leaves at its nodes which are up to 1.5 centimeters long and persistent. Male plants produce pollen cones at the nodes, each up to a centimeter long, and female plants produce seed cones which are slightly larger and each contain one seed in a papery envelope.
