Discussion | Collinsia parryi is most closely related to C. concolor, which has larger flowers arranged in tiers of whorls; their ranges are largely allopatric. Collinsia parryi occurs most commonly on the drier, leeward sides of the Peninsular and Transverse ranges. B. G. Baldwin et al. (2011) sampled chloroplast DNA, ribosomal DNA, and introns of nuclear-coding DNA and showed that many individuals of C. parryi had zero sequence-divergence from C. concolor. This result suggests a recent diversification of these taxa from an ancestor that was most like C. concolor. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Varieties 2 (2 in the flora). Collinsia heterophylla is the most widespread and frequently encountered species in California. There is structure in phylogenetic analysis of northern and southern populations (that is, paraphyly of southern populations) suggesting northward expansion and evidence for introgression with C. tinctoria (B. G. Baldwin et al. 2011) in the southern Sierra Nevada (Kern County and possibly Fresno County). This species is often confused with other collinsias that have tiered whorls of flowers, most frequently with C. bartsiifolia and C. concolor, which both lack the bold horizontal line present at the base of the adaxial corolla lip of C. heterophylla. Plants with reduced corolla pigmentation, nearly white, are uncommon outside of the South Coast Ranges and are often misidentified as C. bartsiifolia. Collinsia bicolor Bentham, which pertains here, is a later homonym of C. bicolor Rafinesque, a synonym of 1. C. verna. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
