12 BOTANY. 
where as a species of Linneus’s. I also include the same name in Porter's 
and Coulter’s Flora of Colorado. 
Ceespitose, more or less woody at the base, forming either a compact 
mass, or sometimes with the stems more lax and lengthened; leaves some- 
times obscurely three-nerved, narrowly linear, more or less roughened ; 
peduncles pubescent; petals longer than the obtuse sepals. 
ARENARIA LATERIFLORA, L.—Twin Lakes, Colorado. (347.) 
Sacina Lina, Presl—Colorado. (341, 342.) 
Drymaria* Eerrusa, Gray (Pl. Wright. 2, p. 19)—Annual, saueedih 
root-leaves ovate, short-petioled, 2’ in diameter; lower internode 2’ long; 
stem-leaves linear-setaceous, 4-8’’ long; dichotomously branched above; 
pedicels very slightly glandular pubescent, twice as long as the flower; 
sepals obtuse, with scarious margins ; petals quite narrow, deeply two-lobed, 
and a little longer than the sepals. The whole plant is hardly three inches 
high. (619.) Sanoita Valley, Arizona, at 6,500 feet altitude. Found, 
so far as I have seen, only among the oak trees and on a gravelly soil. 
PORTULACACEZ. 
PortuLaca OLERACEA, L. ??—The specimens from Colorado (989) are 
all too old to determine with certainty. 
PorTULACA LANCEOLATA, Engelm.?—Arizona. Poor specimens. Chi- 
ricahua, Southern Arizona, growing on dry sandstone rocks. (521.) 
TALINUM AURANTIACUM, Engelm.—Herbaceous, with a woody base, 
1-2° high, erect or sometimes branching from the base, glabrous or with 
a few spreading hairs; leaves lanceolate, thickish, sessile, 1-2’ long; 
peduncles with two small bracts, 4-5” long, articulated above the base; 
flowers orange-colored, single in the axils, somewhat reflexed in fruit; 
sepals 4-5” long; petals somewhat longer; mature seeds black, elegantly 
marked with strong circular lines, and with others less strong, but trans- 
verse to them. (346.) Cottonwood, Ariz., in rocky places. 
*DryMariA, Willd.—Sepals 5, herbaceous or with scarious margins. Petals 5, 2-6-cleft. Stamens 
5, or fewer by abortion, somewhat perigynous. Ovary 1-celled, with many ovules; style 3-cleft. Capsule 
3-valved. Seeds roundish kidney-shaped, or laterally compressed, hilum lateral; embryo peripheral. 
Diffuse or rarely erect herbs, branching dichotomously. Leaves flat, broad or narrow. Stipules small, 
often fugacious. Flowers pedicellate, solitary in the forks, or often in terminal cymes or axillary and 
scattering. BENTHAM & HOOKER.
