Tigridia vanhouttei Roezl ex G.Nicholson is native to Mexico. There are two subspecies, ssp. vanhouttei Molseed and ssp. roldanii Molseed.
Tigridia vanhouttei ssp. vanhouttei is native to Guanajuato, Michoacan, Hidalgo, Morelos, Puebla and Mexico State. This Tigridia species is widely distributed in Mexico, but rare at all localities in its distribution range. It can be found at high elevations between 2250-2850 meters above sea level. It grows best in gravelly, rocky soils but can also be found in dry scrub-brush, stunted Quercus forest, open fields and along roadside cuts. The flowers have a distinctive yeasty, mushroom smell that is produced to attract its insect pollinator. (Some PBS members liken the smell to that of an old tennis shoe cooked slowly over an open fire; it may be that the smell of the species varies from plant to plant, or from grower to grower as some growers report that there is only a very faint smell detected only at very close range.) It is likely, although unproven, that this particular species of Tigridia is pollinated by Dipterids as opposed to Hymenopterids owing to the coloration and fragrance of the flowers. Height range: 45-60 cm. This subspecies is easily distinguished from the other subspecies because it holds its flowers erect whereas the latter has pendulous flowers. The following pictures were taken in September in Texcoco district, Mexico State at 2600 meters. Photos by Dennis Szeszko.

Tigridia vanhouttei ssp. roldanii Molseed is extremely rare and known only from two localities in Hidalgo state. It is considered by the Mexican government to be an endangered species. Photos from iNaturalist were taken by Juan Carlos López Domínguez in June in Tlaxcala, Mexico and shared under a CC BY-NC license. His photos illustrate the pendulous flowers.
