Discussion

It has generally been thought that Zephyranthes atamasca and Z. treatiae are distinguishable only by differences in leaves and habitat, and that their flowers are not significantly different. However, the greater length of the perianth tube compared with that of the filaments in Z. treatiae readily separates that species from Z. atamasca.
