 When I first read the field notes of Annie Alexander and Louise Kellogg, I was fascinated by the descriptions they wrote about the places they went and the plants and animals they found there. By publishing my field notes on the Internet I hope to follow a little bit in their tradition.

    122  Yellow composite without ray flowers.

    Chaenactis glabriuscula DC. var. glabriuscula. Yellow Pincushion.

    Lobo Point, San Bernardino County, California. Lobo Point Camp, 2.6 km northwest of Hole-in-the-Wall, 14.7 km northeast of Mitchell Caverns. 35.0512N, 115.0423W. WGS1984 Elev. 1380 m. Yellow composite w/o ray flowers. Uncommon in the Lobo Point Camp.

    Collected under Permit#: MOJA-2001-SCI-0015, Vegetation of Lobo Point and North Wild Horse Mesa.

    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.

    16 Jan 2014: Collection was discarded because it was badly deteriorated. I am pretty sure this is ssp. tridentata. One voucher of Carl B.
