A SKETCH OF THE BOTANY OF THE BASIN OF THE GREAT SALT LAKE OF UTAH. 169 
S. . . . . eremophyllus. Richards. in Torr. and Gr., fl. 2, p. 444. Stem gla- 
brous, striate, 15—20 inches high; leaves interruptedly pinnatifid, the segments unequal 
with a few teeth. Heads in a loose compound corymb, somewhat larger than those of S. 
aureus, which it resembles much. Great Salt Lake County, April. Mrs. Carrington. 
Terrapymia Nuttall. Torr. and Gr., fl. 2, p.447. Shrubby and much branched, 2— 
3 feet high. Primary leaves mostly converted into subulate spines, the other densely fas- 
cicled in their axils, thickish, linear-spathulate, obtuse, covered with a deciduous tomen- 
tum. Heads fascicled in corymbose clusters on very short peduncles, bright yellow. 
Shores of the Salt Lake, May. Major Stansbury. 
Cirsium undulatum, Spreng. Torr. and Gr., fl. 2, p. 456. (Plumed Thistle.) Cane- 
scently tomentose throughout. Stem low, angled, branched above; branches bearing a 
solitary head; leaves lanceolate-oblong, sinuate-pinnatifid, very white and tomentose be- 
neath ; involucre sub-globose, with lanceolate appressed scales tipped with a weak spread- 
ing prickle; flowers large, reddish-purple. Stansbury Island, June. Major Stansbury. 
STEPHANOMERIA runcinata. Nutt.in Torr. and Gr., fl. 2, p.472. Stem 4—8 inches 
high with flexuous striate branches. Radical and lower cauline leaves runcinate, those 
of the fertile branches linear-subulate; head 5—6 flowered; involucre cylindrical; flowers 
rose colour. Carrington Island, Major Stansbury. 
Licopesm1A juncea. Don. in Torr. and Gr., fl. 2, p. 484. 15—20 inches high, very 
glaucous; stem brauched, striate; lower leaves linear-sublanceolate, rigid; the upper su- 
bulate; head five-flowered, large, fully 12 inch long, with an elongated cylindrical invo- 
lucre of 5—6 scales; ligules double the length of the scales, finely dentate at top, lilac 
colour. It is the same large flowered form mentioned by Prof. Torrey in Stansb. Rep., p. 
392. It is larger in all its parts than any other specimens of the same species, that I have 
seen. The lower stem leaves are 4—4 inches long. The whole plant is very smooth and 
whitish, and grows in various soils on the Islands and Valleys of the Great Salt Lake.

Matacotrix sonchoides. Torr. and Gr., fl.2,p.486. Dwarfish, glabrous; stems branch- 
ing; radical leaves linear-oblong, runcinate, with short approximate lobes spinulosely- 
denticulate; cauline leaves small and scattered; heads of 30—40 small flowers; exterior 
scales of the involucre erose-denticulate; flowers yellow. Shores of the Salt Lake and 
Carrington Island, Major Stansbury. 
CrePis acuminata. Nutt. in Torr. and Gr., fl. 2, p. 489, and Torr. in Stansb. Rep., p. 
392, t. vill. Stem scapiform, 1—5 feet high, sparingly leafy; radical leaves fully twelve 
inches long with the petiole, runcinate-pinnatifid, tapering at the base into a petiole one 
third of its whole length, and at the apex into a slender entire acumination. Heads cy-
