BOTANY. 
rey's 37 from near Donner Pass, appear to be the same — varying in the degree 
of pubescence, leafiness of the stem, and amount of fasciculation, covering both 
nardifolia^ Ledeb., and lyclmidea^ Bieb. Wahsatch Mountains ; G,000 feet 
altitude ; August. First collected by Eicliardson on the Arctic Coast. (166.) 
Aeenaeia Fendleei, Gray. Plant, FendL, ^.13. Stems numerous fi'om 
a perennial caudex, simple, glabrous, imbricately many-leaved at base ; leaves 
long, erect, setaceous, somewhat flattened, scabrous-serrulate, glabrous ; cymes 
strict, few-flowered, and with the sepals glandular-pubescent ; pedicels slen- 
der ; sepals ovate-lanceolate, cuspidate-acuminate, green, with a broad scari- 
ous margin, 3-nerved, nearly equaling the obovate petals ; styles exserted ; 
capsule about equaling the calyx, 6-valved ; seeds obliquely obovate, with a 
minute uncinate micropyle, papillose-scabrous; embryo horseshoe-shaped. 
Var. GLABKESCENS. Nearly glabrous throughout ; the sepals shorter, broadly- 
ovate, acute ; leaves short. It is nearly 70 Hall & Harbour. Found in the 
Toyabe Mountains, Nevada, and in the Wahsatch ; 5-6,000 feet altitude ; 
May-July. The species has been collected in Northern Arizona, New Mex- 
ico, and Colorado. (167.) 
Var. SUBCONGESTA. Glabrous throughout ; flowers more or less clustered 
upon short pedicels, or the lateral ones sessile ; bracts broad and scarious ; 
petals but little exceeding the ovate acuminate scarious sepals. — A low (6' 
high) nearly subalpine form, from the East Humboldt Mountains, Nevada ; 
7-9,000 feet ahitude ; July. Collected also by Burke in Southern Idaho, 
and specimens gathered by Newberry in Northern Arizona and by Anderson 
near Carson City approach it nearly. It is in several respects intermediate 
between congesta and formosa, but seems more closely aUied, through the last 
variety, with the true A. Fendleri, (168.) 
Arenaria pungens, Nutt. Csespitose, minutely glandular-pubescent; 
leaves rigid, subidate, canaliculate, pungent, 3-nerved ; sepals lanceolate, ob- 
scurely 3-nerved, as long as the oblong-ovate petals.— Stems 2-4' high, usually 
forming crowded tufts ; leaves 3-6" long. Collected by Nuttall in the Rocky 
Mountains, in lat. 41°, and by Brewer and Bolander in California. Found 
in the West and East Humboldt Mountains, and in Diamond Valley, Nevada; 
6-9,000 feet altitude ; June, July. (169.) 
Arenaria aculeata. Csespitose, glabrous ; leaves fascicled at the ex- 
tremities of numerous short mostly barren shoots, glaucous, rigid, subulate, 
aculeate; stems nearly naked, somewhat scabrous above; flowers few, (6-8,) on
