lindrical, with very short scales; flowers yellow. Stansbury Island. June. Major Stans- 
bury. 
C. . . . . occidentalis. Nutt. in Torr. and Gr., fl. 2, p.489. Stems scapiform, 
15 inches high; radical leaves runcinate, pinnatifid, tapering into a long petiole, and both 
together 6—12 inches long; divisions narrowly lanceolate, acuminate, sparingly acutely 
dentate; the lower cauline leaves sessile and pinnately parted, the upper ones entire; 
heads large, 3—5 in a paniculate corymb; involucral scales in two series, the internal ones 
very long, narrowly lanceolate, the outer bracteolate; flowers yellow. Nuttall’s specimen 
was a dwarfish state of this rather large plant. Salt Lake Valley, Mrs. Carrington. 
Troximum cuspidatum. Pursh. Torr. and Gr., fl. 2, p. 489. (Acaulescent.) Leaves 
narrowly linear-lanceolate, acuminate, somewhat nerved, especially on the broad midrib; 
the often undulate margins tomentose: scales of the involucre somewhat scarious, lan- 
ceolate, cuspidate-acute, glabrous, in two equal series; flowers large, yellow. Valley of 
the Great Salt Lake, Major Stansbury. 
T. . . . . parviflorum. Nutt. Torr. and Gr., fl. 2, p. 490. Villous-pubescent 
when young, at length glabrous; leaves narrowly linear, lanceolate, acuminate, entire, 
but sometimes retrorsely denticulate towards the base; scales of the glabrous involucre 
lanceolate, acuminate, in 2—3 series, the outer of which is bracteolate; flowers yellow.

ARCTOSTAPHYLOS glauca. Lindl. in D. C. Prodr. VII., p.388. (Bearberry.) A shrub. 
Leaves glaucous, oval-oblong, acute, coriaceous and obtuse at the base; racemes short and 
compound; bracts squamiform; fruits ovate. Pauvan Valley, Mrs. Carrington. 
PRIMULACE. 
DopECATHEON integrifolium. Var. minus? Hook., fl. Bor. Am. 2, p.118. A miniature 
form with flowers scarcely one-third of an inch from the summit of the reflexed divisions 
of the white corolla to the tip of the anthers; scape and pedicels purplish, the latter very 
short and reflexed only in the full expansion of the flowers; involucre of five short folioles, 
broadly ovate and approximate in the form of a truncated funnel; filaments yellow, and 
free immediately below the purple-blue anthers, which are all divergent: capsules not 
seen; leaves oval-oblong, entire, tapering at the base into a narrow petiole; petiole and 
limb 23—3 inches long. Rich soil on the banks of Leven River, Salt Lake Valley, May
