The genus Polianthes belongs to Asparagaceae, subfamily Agavoideae (APG III, 2009) and is endemic to Mexico, spanning the states of Chihuahua and Tamaulipas in the north, and extending to the state of Oaxaca in the south. Its species are perennial, herbaceous plants with corms and bulbs. Their leaves are green or glaucous, linear or lanceolate. Inflorescences are in racemes or spikes with narrow and widely infundibuliform flowers, varying in color from white to red. The fruit is a capsule with black seeds. The number of species of Polianthes varies depending on the criteria to classify them. For example, in the first revision for the genus, Rose (1903) recognized 12 species. According to Espejo and López (1992), the genus has 15 species, whereas GarcíaMendoza and Galván (1995) reported 12 species, and Solano and Feria (2007) recognized 14 species and three varieties.
