Cycladenia humilis var. jonesii (Eastw.) S.L. Welsh & N.D. Atwood
Habit: Plant generally glabrous, glaucous except inflorescence hairy. Flower: perianth with +- not interwoven hairs abaxially or at least on margins, corolla sparse-hairy adaxially, lobes 4--5 mm.
Ecology: Shale slides; Elevation: 2530 m. Bioregional Distribution: W&I (Inyo Mtns); Distribution Outside California: Utah, Arizona. Flowering Time: Jul Note: Unpublished molecular evidence (Slakey, et al., 2011, pers. comm.) suggests that California members of var. jonesii belong instead either to var. venusta or to an undescribed taxon.
Unabridged Note: In Utah, evidently an obligate gypsomorph of +- dry conditions in which flowers are of 2 kinds (evidently, only as to size) within populations (A Utah Flora, Welsh et al., eds., 1993). One collection from California mentioned by Eastwood in protologue (Mark Kerr 3267, CAS, from Inyo Mountains; not seen); Alexander & Kellogg 3058 (UC1036093; 5 July 1942, also from Inyo Mtns), associated with card bearing sketch of flower, and "Cycladenia humilis var. alexandrae (sic), × 2, Alexander & Kellogg 3058, type" handwritten, possibly by Lauramay Dempster (name ined.), and "This is a new species. G.W. Gillett. Aug. 1958" handwritten above collection label.
