Fabaceae Acmispon rigidus

Coll. No. 225, Acmispon rigidus

Coll. No. 225, 27 Apr 2000, characters observed: Herbaceous perennial, woody at base, erect, to 20 cm., not gland-dotted; Leaves, compound, leaflets 3-4, subpalmate (axis apparent beyond lower-most leaflet), main axis extending as a leaflet, leaflets, ovate, 7 mm. × 3 mm. wide, length 2.3 × width, entire, flat, stipules, gland-like, black; Inflorescence, 1-2 flowered, peduncle (5)6-10 mm.; Flower bilateral; Corolla 10 mm.; Calyx, tube 3 mm. + lobes 2-3 mm. = 5-6 mm., tube ≥ lobes; Fruit, 9 mm., flat, curved 90°, beak, 2 mm., straight.

The various combinations of short peduncles, strigose caylx lobes, and curved fruit do not fit any of the taxa known to the eastern Mojave Desert very well. Therefore, A. ridigus is a compromise.

Detail of Coll. No. 675, Lupinus argenteus var. argenteus

Scanned 26 Oct 2011.

This was an attempt to visualize the stem hairs. The question is: are they appressed? The scan makes it look like the stem hairs are spreading, but under the microscope, about 2/3 of the hairs are appressed, and 1/3 spreading.

Characters observed while keying: Perennial > 1 dm, stem hairs appressed, leaves cauline, petioles 4-4.5mm, calyx spurred <= 1 mm, banner back hairy, keel upper margin ciliate distal half.

Weber & Wittmann (2012) use “keel glabrous” as a key character. Harrington (1954) and Ackerfield (2015) neither use keel decoration as a key character nor do they describe the decoration of the keel. California floras, e.g., Munz (1965) and Baldwin (2012), use a ciliate keel, as a key character to identify L. argenteus. Welch, et al. (1993) note that the keel can be glabrous or variously ciliate.

Coll. No. 679, 5 Nov 2011, Characters observed while keying: Perennial, herb, >= 3 dm tall (obs: 4.5-5 dm); Leaves cauline, spread along stem; Leaflets 22-38 mm, upper surface appressed hairy, not wooly; Infloresence open; Pedicels slender, 4-5 mm; Calyx spur mere bulge; Bracts persistent; Flower white, 10-11 mm; Banner base lightly hairy, back glabrous; Keel upper margin ciliate claw to tip not uniform, cilia density increases claw to tip.

Keys to Lupinus holmgrenanus in TJM1, L. gracilentus in TJM2, L. argenteus var. meionanthus in TJDM, and L. pratensis var. eriostachyus in Taylor (2010). The larger flower size of 10-11 mm is usually what gets one off track while keying. Also, the persistence of the bracts can be a problem.

Scanned 17 Jan 2012.

Coll. No. 751, 17 Jan 2012, characters observed while keying: Perennial herb from woody caudex, to 10 cm. tall; Leaves cauline, clustered near base; Stipules 3 mm.; Petioles 3-4 cm.; Leaflets 7, 8-9 mm.; Bracts deciduous; Pedicels 2.5-3.0 mm.; Flower 7(8) mm.; Banner back glabrous; Keel margins glabrous;

Originally assumed to be L. duranii when collected. Could be determined as L. breweri on the basis of smaller stipules, petioles, pedicels and flowers than typically seen in L. duranii. However, given the west-facing sand slope on which this collection was made, I am assuming it is just a small L. duranii.

Keys easily to Lupinus pratensis A. A. Heller var. eriostachyus C. P. Small in Taylor (2010). Keys easily to L. lepidus Douglas ex Lindl. var. confertus (Kellogg) C. P. Small in TJM2. The Plant List, which takes its names for Lupinus from ILDIS (International Legume Database & Information Service), elevates L. lepidus var. confertus to species rank as L. confertus Kellogg. The Plant List also submerges all of L. pratensis A. A. Heller, including var. eriostachyus C. P. Small, in synonomy with L. confertus Kellogg. The family Fabaceae is not published in FNANM (as of 4/27/2015).

Lupinus argenteus rubricaulis

Coll. No. 1984, 23 July 2018, characters observed: Perennial herb, to 65 cm., caulescent, erect; Stem, not winged, Leaves, compound, stipules, free, 7 mm., linear, petiole, 30-32 mm., sparsely appressed hairy, blade, 65 mm. × 67 mm. wide, reduced above, leaflets, #7, 40 mm. × 11 mm. wide, oblanceolate, leaflets generally flat, some younger leaflets folded, adaxial sparse appressed hairy, more dense on mid-rib, abaxial glabrous; Inflorescence, raceme, 133 mm. × 23 mm. wide, many flowers (#34 observed), pedicels, 1.5-2.5 mm.; Calyx, asymmetric, tube 1.5 mm. + lobes 2.0 & 4.5 mm., gibbous rather than spurred; Flower, zygomorphic, banner, 7.5 mm., blue, without yellow spot, reflexed at 2/3, back, glabrous, wings, claw 2 mm. + blade 6.5 mm., white to blue, keel, 8 mm., glabrous, white to purple-black, tip, prominent erect; Ovary, 3 mm. × 0.6 mm. wide, glabrous; Style, persistent; Stigma, simple, glabrous; Fruit, 22 mm. × 6.5 mm. wide, flat, hairs, soft spreading. While this keys fairly easily to var. rubricaulis in Ackerfield (2015) and Welsh et al. (1993), neither mention red stems and petioles in Greene's (1901) original description. Rather they distinguish by the (lack of) folding of the leaflets and the habitat. Weber & Wittman (2012) do not treat varieties of L. argenteus.
