Cholla, Pencil Cholla
Pencil cholla, named for its round, narrow stem segments, is native to the Baja California peninsula in Mexico.
Identification: Forming low shrubs that may be upright or semi-prostrate, plants are less than 31" (80 cm) high. Stem segments are round, 1-4½" (3-12 cm) long × ⅛-⅜" (5-12 mm) in diameter, pale green or brownish green. The tubercules—raised bumps on the stem segments—are small and inconspicuous. The glochids, or groups of small, easily detached spines, are yellow to reddish brown, and ¹/₁₆-⅛" (2-4 mm) long. Spines are sometimes present. Fruits are cylindrical, ½-⅞" (1.5-2.5 cm) long and ¼-½" (8-15 mm) around, tan, and dry. They do not have spines.
