mollissima:*and if there were not what appear to be intermediate
states of it, I should consider it a distinct species. It is less
branched, and has more numerous leaflets than the var. 6. The
flowers are violet, four to six in number, in a short spiked raceme.
The nearly mature legume is densely clothed with long woolly
cream-coloured hairs, and very closely resembles that of P. mol-
lissima. Our plant has much the appearance of hae gla-

a Phaca, but the leaves and fruit are rent. :

Torr. in Frém, 2d Report, p. 314; not of Don. Stansbury’s

mountains of California, along the Virgin River, a tributary of a
the Colorado, It is nearly related to C. Mericana, Don, (in Linn.

Trans. 14, P- 574, t. 22, f. 1,) which has also yellow flowers; but
the leaves in that species are three—parted, with linear segainite,
and they have a long narrowly cuneate base.

‘A third species of this genus, C. plicata, Don, was introduced

‘ into England from Mexico in 1835, and is figured in Sweet’s British

Flower Garden, (t. 400.) This is clearly the plant afterward
described and beautifully figured by Zuccarini in his Plant. Nov.

glandular. The leaves grow mostly font short spurs. They. are :
ovate in outline, 4-6 lines long, deeply cut into five or seyen
lobes, and whitish tomentose underneath, except the strong green :
midrib, but green and somewhat glabrous above. They are revo- 4
lute on the margin, of a coriaceous texture, and sparingly dotted

Tis rare and interesting plant was ing ago proposed as a
distinct genus by the late Mr. Rafinesque. It is allied both to
Fritillaria and to Lilium. It differs from both in the want of
nectaries. Unfortunately the fruit is not known, so that it can-

. According to Mr. Nuttall, Fritillaria tulipefolia of Caucasus is
another species of this genus. I have also specimens of what may
ve to be a third species, collected by Colonel Frémont on the
Feather River, California; fot the style, though thickened at the
summit, is undivided, and the nectary is wanting: but there are
several flowers in a loose racemose panicle.

“sego” by the natives, and is much esteemed by them as food.
It is bulbous, and varies in size from that of a pea to that of a

bert. Our plant agrees exactly with the description of Nuttall,
who was probably mistaken as to the colour of the flower. The
inner sepals seem to be white, except at the claw, which is yellow.
I have not been able to institute a comparison between this plant
and Douglass’s C. luteus; but if ours proves to be distinct, it may
be called C, Nuttallii. |
