SAXIFRAGACEA. 
HeEvcuera rubescens. Torr. in Stansb. Rep., p. 588, t. V. Scape naked, glabrous. 
Leaves suborbicular, 5—7 lobed; lobes crenate, dentate; flowers 15—25, loosely panicu- 
lated in remote branchlets with a small bract at the base of the pedicel. Rhizoma thick, 
somewhat ligneous, clothed with the brown vestiges of anterior leaves. June. Stansbury 
Island, Major Stansbury. 
UMBELLIFER &. 
Tuaspium cordatum. Torr. and Gr., fl. 1, p. 615. (Meadow Parsnip.) Radical leaves 
simple, cordate; cauline ones ternately divided, the segments oval, serrate; winged ribs of 
the carpels equal; flowers yellow. May. Yoab Valley, Mrs. Carrington. 
T. . . . . montanum. Gray, Pl. Fendl., p.57. Stems 5—8 inches high; leaves 
2—3, pinnatifidly cut with oblong, acute, entire or incised lobes; flowers yellow, in dense 
umbels, with numerous rays. May 25th. On a mountain bordering the Salt Lake, Maj. 
Stansbury. 
PrucepANvm ¢triternatum. Nutt. Torr. and Gr., fl. 1, p. 626. 
Var. platycarpum. ‘Torr. in Stansb. Rep., p. 3&9. Root tuberous, large and 
somewhat fusiform. Stems 1—2 feet high; leaves 2—3, ternately divided, segments of 
the leaves 1—3 inches long, 1—3 lines wide, peduncles very long, flowers polygamous or 
dioicious; fruit obovate, very broadly winged, much more so than Nuttall’s plant. Valley 
of the Great Salt Lake, Major Stansbury. 
Leptotenia. . . . . A species of this genus was observed by Colonel Fremont on 
the north side of the Lake. 
VALERIANACES. 
VALERIANA edulis. Nutt. in Torr. and Gr., fl. 2, p.48. (Valerian.) Root fusiform, 
fleshy; stems erect; lower leaves entire, linear-lanceolate, or 1—2, pinnately parted with 
divaricate lobes; the cauline deeply pinnatifid with ciliate linear segments. 
The specimen which I have received, is only the upper part of a stout stem, about 10 
inches long, bearing a long panicle of flowers, fully one half of its length, the two lower 
cymules of which are pedicellate and interrupted. All the cymules are very much crowded 
with flowers. At the base of the panicle are two opposite leaves, palmately pinnatifid, 
with dilated petioles, and three inches below these, another set of opposite leaves, much 
larger, but of the same form, with lanceolate-linear divisions 1 inch long and finely ciliate. 
May. Mrs. Carrington and Colonel Fremont. 
The root is called by the natives Kooyan; when baked on heated stones or steamed 
under ground, it is converted into a pulpy mass, sweet and rather agreeable to the taste, 
which furnishes food to the aborigines.
