Zusammenfassung:Thirty meiotic chromosome counts are reported for 18 species in six families of plants from western Texas, mostly the Trans-Pecos region, and one count each from New Mexico and Mexico. The counts for Perityle microcephala, Echinocereus coccineus var. paucispinus from Bandera County (= subsp. roemeri), Dayia havardii, and the tetraploid counts for Solanum tenuipes var. tenuipes are first reports. The chromosome numbers listed here for other species are consistent with previous reports. Se publican treinta [30] recuentos cromosomáticos en meiosis de 18 especies en seis familias de plantas del oeste de Texas, la mayoria de la región de Trans-Pecos, un recuento de Nuevo México, y uno de México. Los recuentos de Perityle microcephala, Echinocereus coccineus var. paucispinus del Condado de Bandera (= subsp. roemeri), Dayia havardii, y los recuentos tetraploides de Solanum tenuipes var. tenuipes son los primeros realizados. Los números cromosómicos enumerados aquí para las otras especies son consistentes con los informes anteriores.
