Plagiobothrys torreyi var. perplexans I.M. Johnst.
Habit: Annual, +- red, staining, hairs stiff, spreading. Stem: ascending to erect, 0.5--3 dm. Leaf: basal in +- rosette, 1--8 cm; cauline narrow-ovate. Flower: calyx 1.5--2.5 mm; corolla limb 2--3 mm diam. Fruit: nutlet 1.5--1.8 mm, pointed at base, gray to +- brown, arched, +- dull; abaxial ridge, lateral ridges tubercled, cross-ribs rounded, generally with rows of round, translucent papillae.
Ecology: Uncommon. Gravelly soils in chaparral, +- fire follower; Elevation: 500--2100 m. Bioregional Distribution: c&s SN, s SCoRO. Flowering Time: Apr--Jun
Unabridged Note: Intergrades with, most closely related to Plagiobothrys tenellus, Plagiobothrys torreyi var. torreyi, with which it occurs at lower elevations of SNH. Probably more widespread than the few collections suggest. Yrs after publishing it, I.M. Johnston put Plagiobothrys torreyi var. perplexans in synonymy with a red form of Plagiobothrys shastensis, despite significant differences in nutlets and otherwise. Recent California collectors and annotators have misapplied material from SN belonging to Plagiobothrys torreyi var. perplexans to the distinctive Plagiobothrys verrucosus. Plagiobothrys torreyi var. perplexans is morphologically and ecologically consistent throughout its range, and is distinct from Plagiobothrys torreyi s.l., especially with respect to nutlets. Horn's dissertation, in 2000, clearly shows that none of the South America Plagiobothrys species has nutlets similar to Plagiobothrys torreyi var. perplexans.
