Photographs of living plants and the illustration of the new species are provided.

Salvia huastecana Bedolla, Zamudio & H.Castillo-Gómez, sp. nov.
Salviae albiflorae et S. roscidae similis. Sed a priore differt inflorescentia cum 9−12 floribus in quoque verticillastro (vs. 5−9), bracteis floralibus longioribus (5.5−14 vs. 2.5−5.6 mm), apice longe-caudato (vs. acuto vel acuminato), caduco (vs. longe persistente); calyx hirsutus (vs. puberulus trichomatibus adpressus); et a altero differt corolla alba vel alba cum labio supero et labii inferi margine sublazulino (vs. albo).
Distribution and ecology:— Populations of the new species occur in two localities in the municipality of Xilitla,
in the southern portion of San Luis Potosí (Fig. 3). It inhabits on limestone rock slopes with remnant elements of
montane cloud forest with Clethra pringlei S.Watson, Cnidoscolus albidus Lundell, Myriocarpa sp., Podocarpus
reichei J.Buchholz & N.E.Gray, Rhamnus capreifolia Schltdl. y Saurauia sp., in an elevation range from 1427–1465

Etymology:— The specific epithet “huastecana” refers to the Huasteca region, seat of the Teenek or Huasteca
culture that was established more than one thousand year ago in the southern portion of San Luis Potosí (Puig 1991),
area in which the species was found.
