Coll. No. 122, 29 April 1997, characters observed while keying: Annual, tap-rooted, to 15 cm.; Stems, leaves, and phyllaries all wooly; Leaves, alternate, not decurrent, 1°(2°) pinnate lobed; Inflorescence, none of the flowers with strap-shaped corollas, flowers of 1 kind, heads discoid, peduncled, cylindric to obconic; Phyllaries, in 2 series, ±equal (outer ≤ inner), ≤7 mm., green, margins not scarious; Receptacle, epaleate; Pappus, of well-developed flat scales, #4, ≤3 mm.; Corollas, yellow, open during day.

This keyed out fairly easily to Chaenactis glabriuscula var. glabriuscula by way of TJM2 Asteraceae Group 7. However, the location of this collection is way out of range for that taxon. There is one other collection of this taxon from the eastern Mojave (H. S. Reed, s.n., May 5, 1935, Wheaton Springs, UC914160) for which the determination or location has been questioned. If the corolla color is described as “… rarely pale yellow …” then the Chaenactis key takes one to a determination of “Chaenactis hybrid.” However, the yellow color of the corolla looks strong to me, which pretty much forces one into Chaenactis glabriuscula.

Read this, "[hairs have a] … swollen base, surrounded by a tesselated rosette of radially oriented cells." Wish I had written that description.

16 Jan 2014: Collection was discarded because it was badly deteriorated. I am pretty sure this is ssp. tridentata. One voucher of Carl B. Wolf #2521 (UC527143), made at Farrington Ranch, has been determined ssp. vaseyana, but I think that determination needs to be made in the field because part of the diagnosis is by growth form.
