Coll. No. 122, Chaenactis glabriuscula

Comments: 7 Nov 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.

Coll. No. 724, Symphyotrichum spathulatum

Comments: 25 Oct 2012, Coll. No. 724, 1 Sep 2010, Characters observed while keying this collection: Perennial from fibrous roots and rhizomes, not thistle-like; generally > 4 dm tall (observed 3.5-4.5 dm); Stem pubesence uniform and sparse; Leaves basal withered at flowering, altho' formerly larger than cauline leaves, without spinulose tip; Peduncle not glandular; Involucre not glandular; Receptacle naked; Phyllaries in multiple series, could be >3; Outer phyllaries not chartaceous (paper-like) but could have scarious margins to half their length, elongate green area at tip, tip acuminate; Flowers not all ligulate; Ray flowers conspicuous, color violet or purple; Disk flowers style branches not tipped with tufted yellow hairs; Achenes with pappus of hairs.

Originally guessed to be Erigeron philadelphicus, but in Taylor's (2010) key, phyllaries in multiple series leds one away from Erigeron. Then I got lost in Symphyotrichum over the question of what basal leaves "present at flowering" means relative to "withered." This led me into S. lanceolatum. With the help of John Strother, I came to see that even though the basal leaves were withered, they were clearly formerly larger than the cauline leaves. This put me on a different path leading, eventually, to S. spathulatum.

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). Weitemier (2010) concludes that varieties of L. lepidus are ecotypes, recommends that they continue to be recognized at the varietal rank per Clausen, et al. (1939).

No. 1059, 28 Aug 2014: Perennial herb, of eastern slope, to 50 cm.; Leaves alternate, to 12 cm. × 2 cm. wide; margin shallowly toothed; Bracts, 15 mm., pinnately toothed, some basal and some clearly arising from the capsule; Petals, 10+, 40 mm. × 7 mm. wide; Stamens many; Filaments broad, narrowing at distal end; Anthers basifixed; Capsule, 30 mm. × 10 mm. diameter, erect, not curved at base, thick cylindric; Calyx (in fruit), lobes 9-12 mm.; Seeds, horizontal in capsule and winged, 3.8 mm. × 2.5 mm. wide, wing width 0.5-0.8 mm.

Typically, M. nuda is described as having “1 or 2 bracts usually at base” of capsule (Harrington, 1954), or “bracts not fused to ovary wall” (Weber & Wittmann, 2012), or “bracts free from capsule” (Ackerfield, 2015). However, this collection clearly has 15 mm. pinnatifid bracts arising from the capsule. Such character would lead to M. decapetala. Regardless, the small size of those bracts, and small size of other characters support placing this in M. nuda rather than M. decapetala.

Name List: Veronica anagallis-aquatica  

1202. Veronica anagallis-aquatica L. Growing in running water, just below an old road. Northern portion of the Survey Field, 2.1 km south southwest of the GNIS location of Golden. (39.7379,-105.2291,WGS 1984.) 7/12/2015 Colorado School of Mines Survey Field, Jefferson County, Colorado. (CAS , CS , KHD00061541 , UCR267679 )

Comments: 2015, Coll. No. 1202, 12 July 2015, characters observed: Leaves, sessile and clasping, 35 mm. × 11 mm. wide, length 3.2× width, elliptic; Inflorescence, flowers in axillary racemes; Corolla, 3 mm, limb 5 mm., blue; Capsule, notched 0.2 mm.

The three Colorado floras, Harrington (1954), Weber and Wittmann (2012), and Ackerfield (2015), and one checklist (Snow, 2009) are inconsistent regarding recognition of V. anagallis-aquatica and V. catenata in Colorado, with V. salina mixed in. I have followed Ackerfield (2015). For Utah flora (Welsh, et al., 1993), this collection is firmly in V. catenata, whereas the Jepson Manual (Baldwin, 2012) clearly places this collection in V. anagallis-aquatica. We eagerly await the FNANM treatment.

Entire leaves of Coll. No. 1281, Artemisia ludoviciana

Comments: 2016, 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.

I'm going with Ranunculus acris on this one rather than R. acriformis because: (1) sepals are spreading, not reflexed, (2) large petals, (3) the achene beaks don't look like they will become abruptly curved as they mature.

Definitely Linum, maybe L. perenne because the styles are consistently longer than the stamens, which, in Weber & Wittmann (2012), would put us in L. perenne rather than L. lewisii. The key in Ackerfield (2015) does not discriminate between the two taxa based upon characters that can be observed with this collection.

North slope of Rabbit Ears Range, along Willow Creek and Forest Road 106, 7.4 km. north of Haystack Mountain, 6.7 km. south of Rand. (40.3942,-106.1879,WGS 1984) Common, especially along roadsides. This area extensively collected by J. E. Tear, Jr. (1993-1995, 135 collections, deposited at CS) and B. E. Nelson (2000, 145 collections, deposited at RM). 6/20/2018 Willow Creek, Jackson County, Colorado. (OBI170740 , UC )

Coll. No. 1953, Ipomopsis aggregata ssp. attenuata

Comments: 12/26/2018, Coll. No. 1953, 20 June 2018, characters observed: Calyx, tube 2.5-3.0 mm. + lobes 3.5-4.0 mm.; Corolla, filiform, tube 20 mm. × 1 mm. wide flaring gradually to 3 mm. + lobes 7.5-8.0 mm.; Anthers, close to orfice.

Two subspecies of Ipomopsis aggregata (Pursh) V.E. Grant have been collected within ½ km. radius of this collection. J. E. Tear, Jr. #258, 1993-06-16, CS81546, was determined I. a. subsp. weberi V.E. Grant & Wilkin by Ackerfield. Ackerfield (2015) now treats subsp. weberi as a synonym of I. a. subsp. attenuata (A. Gray) V.E. Grant & A.D. Grant. B. E. Nelson #49939, 2000-6-27, RM760254, was determined I. a. subsp. aggregata.

This specimen will key ambiguously to either subsp. attenuata or subsp. aggregata in Ackerfield (2015) depending upon how much weight one places on the shape of the corolla tube vs. the position of the anthers. However, this specimen keys unambiguously to subsp. attenuata in Grant & Wilkin (1986) based upon the shape and dimensions of the corolla tube and the position of the anthers.

Comments: 12/8/2019, Coll.

I applied M. micrantha because the inflorescence greatly exceeds the leaves and the plant is floriferous nearly to the base. Also hairs are hooked on the abaxial mid-rib of the leaves, a character only described for M. micrantha (see the Jepson Manual of California, 2nd ed.). This will key to M. arvensis in Ackerfield (2015). However, M. micrantha is not a possibility there. Distribution of collections of the two taxa (SEINet, 8 Dec 2019) show collections of M. micrantha in northeast Utah and southeast Wyoming, whereas collections of M. arvensis are much farther from Colorado.

Keys to S. nemoralis in Weber & Wittmann (2012) and FNANM per the form of the inflorescence, yet the description in FNANM better describes this as S. nana especially in the number of phyllary series, and relative number of ray and disk flowers. Based on the key in Ackerfield (2015), would key to S. nana based upon the relative number of ray and disk flowers in the heads. Based upon the description in Ackerfield (2015), very similar to S. nana but S. nemoralis is a better fit because the ray flowers, disk flowers, and the cypselae are shorter.

Comments: 12/30/2020,

I'm not sure what this is. It keys to Solidago nemoralis var. decemflora in Ackerfield (2015), but does not look much like photos or voucher images on SEINet. It keys to S. nana in Weber & Wittmann (2012), but also does not look much like photos or voucher images on SEINet. It does seem to fit into Solidago subsect. nemorales per Semple (2018). I suppose it could be a hybrid of some sort. I am open to other suggestions.
