Title: Chromosome Numbers of Neotropical Castilleja (Scrophulariaceae: Tribe Pediculareae) and Their Taxonomic Implications
Abstract: Meiotic chromosome numbers in Castilleja are reported for 105 collections representing 34 species, mostly from Mexico, with a few from Central America and South America. Chromosome numbers of the following 19 species are reported here for the first time: C. bryantii, C. ecuadorensis, C. fissifolia, C. fruticosa, C. gracilis, C. hirsuta, C. integrifolia, C. irazuensis, C. linifolia, C. nubigena, C. ornata, C. ortegae, C. purpusii, C. roei, C. scorzonerifolia, C. stenophylla, C. talamancensis, C. tenuifolia, and C. virgata. Of the 34 species, 24 are exclusively diploid (n = 12); five are tetraploid (n = 24) only; two are octoploid (n = 48) only; three have two or more levels of ploidy (n = 12, 24, and 72)
