Grassy openings beside a small watercourse, about 350 m south of City of Golden Beverly Heights Park, 2 km south southwest of the GNIS location of Golden. 39.738N, 105.2274W. WGS 1984. Elev. 1868 m. Tiny annual with small rosette of leaves, a single scape, and a small inflorescence. Collected with Cerastium arvense ssp. strictum and Carex inops ssp. heliophila.

Coll. No. 1080, 23 April 2015, characters observed: Annual, to 5 cm., inconspicuous, seen only while lying in grass to collect a sedge, non-glandular hairs branched, glands few; Leaves, basal, 8 mm. × 1.8 mm. wide, elliptic, slightly narrowed at base but not clearly petioled; Peduncle (scape?), 40 mm.; Bracts, 3.7 mm., elliptic; Pedicel, 6 mm.; Sepals, 4 mm., prominently 1-veined, but keel not apparent in dry specimen, papery where united (could be described as a calyx with lobes ±= tube); Corolla, <calyx, white.

  The name was first used by Pedanius Dioscorides in De Materia Medica (c. 40) as the Greek name for an uncertain marine plant (probably a species of Acetabularia), derived from andrs (genitive of an?r man) + -akes, derivative of kos cure). The root was probably misconstrued by Linnaeus as a compound with Greek skos shield, when applied to the land plant in the Primulaceae, meaning andros, male, and sakos, shield, alluding to anther shape.

1126  Grass, near top of Mt. Falcon, growing in rocks and on wooded slopes, perennial bunch grass, no rhizomes.

Poa fendleriana (Steud.) Vasey. ssp. fendleriana Muttongrass.

Mount Falcon Park, Jefferson County, Colorado. Just south of the main observation tower on the top of Mount Falcon. 39.6296N, 105.2306W. WGS 1984. Elev. 2391 m. Perennial bunchgrass, growing in rocks and on wooded slopes, spikelets light and dark colors, no rhizomes.

Coll. No. 1126, 1 June 2015, characters observed: Perennial grass, of shady dry places, to 40 cm., not rhizomatous; Leaves, sheath, open ½, ligule, membraneous, ±1 mm., auricles 0, blade, soft, short and rolled distally; Inflorescence, panicle, 3°-4° branches, somewhat contracted, i.e., not broad, branches sparsely scabrous; Pedicels, 1.5-2.5 mm., short ascending hairs; Spikelets, 1 per node; Compression lateral; Glumes, 2, lower, 3 mm., <lowest lemma, upper, 4 mm., Florets, 5-6, lowest 1-3 pistillate, upper undetermined but no evidence of stamens; Callus glabrous; Rachilla, extends beyond upper floret; Lemma, 4 mm., keeled, veins 5, tip obtuse, awns 0, wavy hairs proximal half of keels and margins; Palea, 2.3 mm., transparent, keels green and hairy.

Didn't feel very confident about my determination on this one. Checked it out again. Keys easily to Poa fendleriana in Shaw (2012), but in Ackerfield (2015) it gets lost at 2a-2b over the shape of the panicle, i.e., is it “open or loosely contracted” vs. “narrow and tightly contracted.” I would say “loosely contracted,” which leads most easily to P. wheeleri. P. wheeleri has not been collected in Jefferson County.

Literature Cited:
- Nesom, Guy L., and Gary I. Baird, 1993.  

Neson and Baird (1993) placed Chrysothamnus nauseosus and similar taxa within Ericameria based on their dissimilarity to Chrysothamnus and their similarity to Ericameria, as noted by commentaries in earlier literature and corroborated by their observations, and by comparative embryology, latex production, DNA variation, and various other chemical studies. Together, these suggest that similarities in phyllary arrangement have been unduly weighted in the definition of Chrysothamnus.

Neson and Baird (1993) defined Ericameria nauseosa (Pallas ex Pursh) Nesom & Baird subsp. nauseosa, including the following varieties (the gray forms): bemardina, bigelovii, glabrata, glareosa, hololeuca, iridis, latisquamea, nana, nauseosa, psilocarpa, salicifolia, speciosa, texensis, and washoensis.

For the common variety of Ericameria nauseosa in the Golden, Colorado, Nesom and Baird (1993) define Ericameria nauseosa (Pallas ex Pursh) Nesom & Baird var. glabrata(A. Gray) Nesom & Baird, comb. nov. BASIONYM: Bigelovia graveolens Nutt. var. glabrata A. Gray, Proc. Amer. Acad. Arts 8:645. 1873. Synonym: Chrysothamnus nauseosus (Pallas ex Pursh) Britt. subsp. graveolens (Nutt.) Hall & Clements, Carnegie Inst. Washington Publ. 326:214. 1923.

We now use the name E. nauseosa var. graveolens (Nuttall) Reveal & Schuyler, published in Proc. Acad. Nat. Sci. Philadelphia. 149: 20. 1999. I have been unable to obtain that publication, so I don't know the rationale for using the name var. graveolens.

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.

1149  Geranium, pink, sticky.

Geranium caespitosum James. Pineywoods Geranium.

Colorado School of Mines Survey Field, Jefferson County, Colorado. Northwestern corner of Survey Field, 50 m east of Windy Saddle Park boundary at base of Lookout Mountain, near City of Golden water tank and site of former Lookout Mountain tramway, 2.25 km south southeast of the GNIS location of Golden. 39.7365N, 105.2301W. WGS 1984. Elev. 1914 m.

It's not crystal clear that this is G. caespitosum vs. G. viscosissimum, especially since this collection includes neither fruit nor basal leaves.

Aedo (2001) distinguishes between then two taxa on the ratio of fruit length / stigmatic remains length, and the width of the basal leaves. Weber and Wittmann (2012) use the shape of the plant, i.e., erect with 1 or few stems, vs. many stems, often sprawling. Ackerfield (2015) distinguishes between the two taxa on the width of the basal leaves, and the shapes of the lobes thereon. Harrington (1954) distinguishes between G. caespitosum and G. nervosum Rydb. (=G. viscosissimum) on the basis of single stems from a branched caudex vs. multiple stems from a simple caudex. So, it would appear important to collect fruit or pay special attention to the basal leaves, the caudex and how stems arise from the caudex.

The California treatment of Geranium was authored by Carlos Aedo where G. caespitosum is not recognized.

Collection #793 is very similar. After originally determining the collection as var. dudleyi, I changed my mind to var. humilis. Now, I'm not so sure that was correct. Collection data in Mono County shows many of the collections are not determined to infraspecific taxa, and many that are determined to infraspecific taxa are sympatric with the other variety.

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.

According to Roskill, a mineral consulting firm, the total global demand for lithium reached 150,000t LCE. The total value of the global demand is estimated at more than $2 billion.

Since the start of this millennium, lithium demand has increased at an average CAGR of 6.8%. Going forward, Roskill expects demand to grow at an annual base rate of 9.7% until 2017. According to Roskill, consumption of lithium in volume terms will be mostly driven by the rechargeable battery market. The rechargeable battery market is forecast to grow at 21.5% per year.

The growth in the rechargeable battery market is being driven by the fact that lithium-ion batteries are crucial in portable and mobile applications. In fact, the growing use of smartphones and tablets is one of the key drivers of the market and will remain so going forward.

Orocobre Limited, citing a Citigroup forecast from 2012, noted in a report that the lithium-ion battery market is expected to rise from $13.9 billion in 2011 to $34.3 billion in 2020. This is significant growth and not surprisingly, the market has been bullish on lithium miners over the past few years.

This morning one such miner, Dajin Resources Corp. (TSX-Venture: DJI) reported that its wholly-owned subsidiary Dajin Resources (US) Corp. has completed a 550 station gravity survey at Alkali Lake. Vancouver-based Dajin is an energy metals company with strategically located brine-based lithium exploration projects in both South and North America.

The Alkali Lake project comprises of 138 placer claims, spread over an area of 1,138 hectares or 2,811 acres. Surface sampling conducted in March and April confirmed the presence of near surface lithium. DJI said that the results of the gravity survey are now undergoing processing.

The basin is situated close to Rockwood Lithiums Clayton Valley/Silver Peak lithium operation, which is the only producing brine-based lithium mine in operation in North America.

Apart from Alkali Lake, Dajin also has a 100% interest in claims known to contain lithium and boron values in the Teels Marsh region of Mineral County, Nevada. The claims are spread over an area of 2,187 hectares and are close to the Mono Lake Crater, a lithium rich mega volcano. This volcano is possibly the source for lithium rich volcanic ashes blown eastward to depositions in local basins such as Teels Marsh. In addition, Dajin also has a 100% interest in concessions or concession applications in Jujuy Province in Argentina.

Investors seem to like the progress and prospects for Dajin as shares are up over 100% in the last 12 months alone, currently trading at $0.08 a share with a couple hours of trading left in the day.

Only var. geyeri is recognized in Colorado per Weber & Wittmann (2012) and Ackerfield (2015). However, the green apical zones of these phyllaries are more diamond-shaped than lanceolate suggesting var. laeve, especially if the phyllaries are described as strongly unequal. The possibility that these plants should be assigned to var. laeve or that var. geyeri should be considered a synonym of var. laeve is discussed in FNANM.

1281  Field identification: Artemisia cf. ludoviciana.

Artemisia ludoviciana Nutt. Silver Wormwood.

Ranson/Edwards Homestead Open Space Park, Jefferson County, Colorado. High plains above Rocky Flats, 15.2 km north northeast of Golden, 1.3 miles north of CO State Highway 72 on Plainview Road, then 535 m. west of Plainview Road. 39.89N, 105.2682W. WGS 1984. Elev. 2001 m. Leaf margins entire. In a grassy low spot away from established drainage.

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.
