Erirricuium. —? An apparently new species was found at Sitgreaves’s Pass, March 25. It 
is an annual, a foot or more in height, and paniculately branched.. The leaves are lanceolate 
linear, scabrous, with short stiff hairs, many of which have a white elevated tubercular base. 
The flowers are in compound ebracteate spikes, which are at first short and Circinate-capitate, 
but at length unfolded. Pedicels almost wanting. Segments of the calyx lanceolate, densely 
clothed with short rather soft hairs. Corolla white; the tubes scarcely longer than the calyx; 
the orifice closed with five protuberances, which alternate with the stamens; limb widely ex- 
panding; the lobes nearly orbicular. Stamens included, inserted in the throat of the corolla 
just below the protuberances. Style as long as the ovary; stigma capitate, somewhat 2-lobed. 
Nublets narrowly oblong, only one of them fertile, minutely bispid. This is allied to E. flori- 
bundum, Yorr., which differs in being a considerably larger plant, with an apparently peren- 
nial root, broadly ovate nutlets.

Var.? BIPINNATIFIDA: patenti-pilosa; caule debili prostrato; foliis bipinnatifidis; pedunculis 
calyce subtriprolongioribus. Camp 61. Yampai valley. In the flowers this plant entirely 
resembles P. micrantha. The more divided leaves and longer pedicels may be owing to a 
more shady and fertile — > ‘‘The plant is very fragrant; the odor being much like that 
of the apple geranium.’ 
PHACELIA saeiaonke IVESIANA, (n. sp. :) annua erecta, vel diffusa, viscido-pubescens ; foliis 
oblongo-linearibus, pinnatifidis, lobis utrinque 5-7 obovatis obtusis integris vel 1-2-dentatis, 
petiolatis basi nudis; racemis simplicibus paucifloris, floribus brevissimi, pedicillatis calycis 
lacimis spathulatis, erolls tubuloro-campanulata calyce vix excedente; placentis 8-9 ovulatis. 
Diamond river; April 3. Sandy hills, Oraybe; May 13. Banks of the Colorado; March 20. 
Camp 49. Plant 6-10 inches high, apparently diffuse when old. Leaves 4 to 1; inch long 
and of an inch wide; the lobes scarcely 2 lines long. Racemes 5-10 flowered; pedicels about 
half a line long. Corolla white or very pale purple, about two lines long, the tube three times 
as long as the rounded lobes of the limb ; appendages very narrow. Stamens included. An- 
thers broader than Jong. Capsule Shalt Seeds strongly rugose transversely. In the corolla 
this species resembles P. infundibuliformis, but differs in the few flowers, the few-flowered 
racemes, and in the very small lobes of the leaves.
