Plants acaulescent, cespitose; rosettes from vertical, subterranean, branched caudices. Leaf-blades wiry, carinate, flat or concavo-convex, 100–200 cm × 5–10 mm, not glaucous; margins remotely serrulate, with widely separated, noncartilaginous teeth, to entire; apex lacerate.

Discussion

Of conservation concern.

Nolina arenicola is endemic to the trans-Pecos region of Texas and is listed as threatened and endangered by the U.S. Fish and Wildlife Service. Nolina arenicola is similar to N. texana except that in N. arenicola the clumps are much more robust, with wider leaves, serrulate near the point of attachment, and are restricted to sandy areas.
