Discussion
Type. Mexico. Baja California Sur: Sierra de Laguna, 22 Jan 1889, T. S. Brandegee s.n. (YU!).
This differs from congeners in Mexico, and especially from its nearest ally, A. fibrillosum, in having rachises scantily pubes cent (vs. distinctly fibrillose), forked veins (vs. simple), and indusia delicately ciliate (vs. deeply laciniate).
