Alligator juniper

Description:

The bark is usually very distinctive, unlike other junipers, hard, dark gray-brown, cracked into small square plates superficially resembling Alligator skin; it is however sometimes like other junipers, with stringy vertical fissuring. The shoots are 1-1.5 mm diameter; the leaves are arranged in opposite decussate pairs or whorls of three; the adult leaves are scale-like, 1-2.5 mm long (to 5 mm on lead shoots) and 1-1.5 mm broad. The juvenile leaves (on young seedlings only) are needle-like, 5-10 mm long. The cones are berry-like, 7-15 mm in diameter, green maturing orange-brown with a whitish waxy bloom, and contain 2-6 seeds; they are mature in about 18 months. The male cones are 4-6 mm long, and shed their pollen in spring. It is largely dioecious, producing cones of only one sex on each tree, but occasional trees are monoecious.

Habitat:

It is native to central and northern Mexico (from Oaxaca northward) and the southwestern United States (Arizona, New Mexico, western Texas). It grows at moderate altitudes of 750-2700 meters (2450-8900 feet) on dry soils.

Notes:

These trees were all over Bandera volcano.
