Discussion | Species ca. 30 (2 in the flora). Habranthus species have at times been included in the genus Zephyranthes. The somewhat zygomorphic flower of Habranthus is clearly distinguished by filaments of 4 different lengths, which are fasciculate to semifasciculate, and always longer than the perianth tube. The actinomorphic flower of Zephyranthes is distinguished by filaments of two lengths (sometimes subequal), which are not fasciculate and are spreading except when shorter than the perianth tube. All measurements were taken from pressed, dried specimens. Generally, the maximum width of a fresh leaf would be about one and one half times that reported here.
