Discussion | Varieties 4 (4 in the flora). (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.) |
