Discussion | Varieties 3 (3 in the flora). Castilleja subinclusa is divided into three varieties with somewhat discontinuous ranges. Identification of the varieties is often difficult when comparing only a single trait but is more easily accomplished when the characters are considered in a suite. The three varieties are also separable by range and habitat. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Castilleja indivisa is native in Texas and adjacent states. In Mexico it is rare, with collections only from two states; these are likely waifs. This species is possibly extirpated from Arkansas. Records from Alabama (starting in 1995) and Florida (starting in 1961) are adventive populations, often on roadsides, and in some cases spreading from ornamental highway plantings. Castilleja indivisa usually has bright red bract apices and red, white, or pale pink calyx apices, but many color variants are found in nature and in cultivation, including individuals with the distal portion of the bracts colored white, pink, pale yellow, peach, or, very rarely, magenta. Uniformly white-bracted populations occur on the margins of tidal salt marshes in a small area of Nueces County, Texas, between Aransas Pass and Port Aransas. These populations likely deserve nomenclatural recognition, due to their combination of consistent coloration and unique habitat. While the main bloom period is in the spring, summer rains often allow continuing or renewed flowering during virtually any month of the year. Occasionally, plants show variation in leaf lobing; this likely reflects introgression from the C. purpurea complex, at least in some cases, such as in Coleman and McCullough counties, Texas.
