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.
