In Weber & Wittmann (2012) and Ackerfield (2015) will key to Artemisia ludoviciana Nutt. var. ludoviciana, because of the entire leaves. However, in FNANM, revolute margins lead one away from subsp. ludoviciana, perhaps in the direction of subsp. mexicana (Willdenow ex Sprengel) D. D. Keck. Most of the collections of A. ludoviciana Nutt. in Jefferson County, Colorado, are undetermined as to infraspecific taxa, and considerable variation in leaf margins and lobes can be seen in the specimens.

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.

Collection No. 1063, 17 September 2014, characters observed: Perennial shrub, woody at base, to 1 m., sprawling to erect; Stem covered with felt-like tomentum (long hairs infiltrated with resin, must scrape with knife to expose); Leaves, alternate, lance-linear, 70 mm. × 3 mm., not twisted in the manner of some related species, upper surface tomentose, margin entire; Heads discoid (with only disk flowers), cymose at ends of branches, narrowly tubular; Involucre 8 mm., not spiny; Phyllaries in 3 vertical ranks, outer << inner, keeled, some with few short hairs; Receptacles not chaffy, but have some short (<0.5 mm.) appendages between flowers; Flowers #5; Corolla tube (i.e., petals united at base) 7.5 mm. + lobes #5, 1 mm., glabrous throughout; Ovary inferior; Pappus of bristles, 6-7 mm., white; Stamens 5; Anthers connate (united), 2 mm., acute at base; Style 11 mm., branches half-round in cross-section, stigmatic 1 mm. + appendage 2 mm., glabrous inside, uniformly short hairy on outside, tips rounded; cypselae, all similar in shape, 5 mm., short hairy;

Not known from California. In Ackerfield (2012), Asteraceae, Key 2, 15a-b, a question of how tomentose the stems and leaves are made keying tricky.

Scanned 17 March 2011. Background grid is 10 x 10 to the inch.

What I think I'm seeing here is that the stems are tomentose, except where recently split, infloresence paniculate, and the phylarries are pubescent to tomentose.

The three things to see here are:

1. The fruit is hairy, which eliminates var. leiosperma.
2. The style appendages < stigma, which eliminates var. speciosa and others.
3. The corolla lobes are large (2 mm.) which eliminates var. hololeuca.

Coll. No. 1025, 24 Jul 2014, characters observed whilst keying: Perennial to 1 m., stem and leaves without round, ±evenly spaced resin-filled pits; Leaves, thread-like; Phyllaries in 4 series, 2-ranked, aligned vertically, tips erect; Rays 0; Disc flowers, corolla lobes 2 mm.; Style, stigma 2.0 mm., appendage 1.8 mm.; Fruit, 2.5 mm. hairy.
