Resumen de New Combinations in Habranthus (Amaryllidaceae) in Mexico and Southwestern U.S.A
Raymond O. Flagg, Gerald L. Smith, Alan W. Meerow
New combinations in Habranthus Herb. (Amaryllidaceae) are made for four species that were previously treated as Zephyranthes Herb. (Z. arenicola Brandegee, Z. chichimeca T. M. Howard & S. Ogden, Z. conzattii Greenm., and Z. longifolia Hemsl.) and that are endemic to Mexico and the southwestern United States: H. arenicola (Brandegee) Flagg, G. Lom. Sm. & Meerow, H. chichimeca (T. M. Howard & S. Ogden) Flagg, G. Lom. Sm. & Meerow, H. conzattii (Greenm.) Flagg, G. Lom. Sm. & Meerow, and H. longifolius (Hemsl.) Flagg, G. Lom. Sm. & Meerow. The mature anthers, which are more or less horizontal and usually lunate or U-shaped, readily distinguish Habranthus from Zephyranthes, in which the mature anthers are vertical and relatively linear.
