Artemisia ludoviciana

Entire leaves of Coll. No. 1281, Artemisia ludoviciana

Scanned 15 January 2016.

The leaf margins are entire and revolute.

In Weber & Wittmann (2012) and Ackerfield (2015) this collection 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.

Artemisia ludoviciana ludoviciana

Coll. No. 898, Artemisia ludoviciana ssp. ludoviciana

Scanned 25 August 2013.

Coll. No. 898, 24 August 2012, characters observed while keying: Perennial herb, to 40 cm, unarmed, spreading by rhizomes; Leaf tomentose abaxially, sparse tomentose adaxially, proximal wedge-shaped, 40 mm × 15 mm wide, 3+-toothed, ≤⅓ leaf-width, distal lanceolate, entire;

Frequency and depth of leaf lobing distinguishes between ssp. ludoviciana and ssp. incompta. These leaves are neither 2°-divided, nor deeper than ⅓-width, nor divided nearly to the mid-rib. Therefore, ssp. ludoviciana is applied rather than ssp. incompta.

Chaenactis glabriuscula

Coll. No. 122, Chaenactis glabriuscula

Scanned 7 November 2013.

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.
