About plant names...

Tenaza is a North American native from Texas and Mexico.

Identification: This is a shrub or small tree 10-20' (3-6.1 m) tall, and about the same around. The trunk has paired straight spines and smooth, thin bark that is gray or sometimes reddish in color. Leaves are grayish green, bipinnate, 4-6" (10-15 cm) long, with 7-20 pinnae (pairs of leaflets), each with 30-40 leaflets. Fragrant flowers are cream-colored, ball-shaped, ½-1" (1.3-2.5 cm) in diameter, appearing from May to mid-September. They are often described as “cream-colored puffballs.” Brown bean-like seedpods are flat, velvetlike, 2-5" (5-12 cm) long.
