Kirk (Stud. Fl. 1899, 240-241) distinguishes 2 forms under his account of C. acerosa : "Two prevailing forms may be distinguished, though closely connected by intermediates, as follows:--(1) arenaria. Branches numerous, with yellowish-brown bark . . . Leaves numerous, very narrow-linear, close-set. Drupe rarely exceeding 1/6 in. long, white, translucent. (2) brunnea. Branches fewer, stouter, with dark-brown bark . . . Leaves more distant . . . Drupes larger, 1/4 in. long, subglobose or broadly oblong, translucent, pale-blue."
