DOCUMENTED CHROMOSOME NUMBERS 2017:1. MISCELLANEOUS COUNTS MOSTLY FROM WESTERN TEXAS (U.S.A.), ONE EACH FROM NEW MEXICO (U.S.A.) AND MEXICO

摘要

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 Solatium tenuipes var. tenuipes are first reports. The chromosome numbers listed here for other species are consistent with previous reports.
