Tigridia pavonia is native to America and may be found in locations from Mexico southwards to the Andes. It is considered that Mexico has the widest diversity of species of the genus Tigridia, and within Tigridia pavonia nine different botanical varieties have been collected. The description of those varieties is the aim of this paper. Three collections of T. pavonia were performed at three different sites within Mexico State: 1) Temascaltepec 2250 m a.s.l., 2) Tenancingo 2100 m a.s.l., 3) Temoaya 2600 m a.s.l. and six, one and two botanical varieties have been collected respectively. Plants were grown in greenhouse at the Agricultural Science Faculty at Universidad Autonoma del Estado de Mexico, 2600 m a.s.l., and were characterized according to seventeen pertinent descriptors. Quantitative descriptors were subjected to a variance analysis under a completely randomised design, and a multiple rank test of Tukey was applied. The descriptors that are proposed to distinguish among botanical varieties are: length of shoot, number of branches per floral shoot, number of fruits, principal colour of the flower, background colour, shape of external tepal, dominant colour of staminal column, and distance from the base of anther to stigma.
