and the petals larger, much exceeding the calyx, and bright yellow. 
It ranges from Vancouver Island and British Columbia to Idaho 
and Oregon. A specimen also belonging here, without doubt, but 
less pubescent, has been collected in Utah by Marcus E. Jones. 
Fendler’s no. 197, from Santa Fé Creek, New Mexico, which was 
included in P. fissa major by Lehmann, resembles the typical form 
except that the petals are smaller, scarcely exceeding the sepals.

The flowers resemble much those of the preceding, the petals 
being bright yellow, very large, orbicular, very concave, and much 
exceeding the ovate-lanceolate long-acuminate sepals; but the 
habit is very different. P. fissa is a low plant, seldom exceeding 
2 dm. high, very bushy, with a narrow and few-flowered cyme; 
also often with some flowers in the axils of the leaves. The leaves 
most resemble those of the next, but the leaflets are generally more 
rounded and with stronger veins. The type specimens of P. 
scopulorum are less glandular than the original of P. fissa, but very 
glandular specimens have been collected even in Colorado. P- 
fissa occurs in the higher Rockies. It is common in Colorado, 
rare in Wyoming, Idaho and Montana. 
POTENTILLA GLANDULOSA Lindl. Bot. Reg. 19: p/. 1583. 1833. 
Resembles P. g/utinosa in the open many-flowered cyme and 
general habit, but is a much more slender plant. It resembles E 
Jissa in the leaves, the long sepals and the shorter glandular pubes- 
cence, which is sometimes rather sparse. It differs from both by 
its petals, which are obovate, flat and about equal the sepals. 
Next to P. arguta, it is the most common and has the widest 
range of the group. It extends from British Columbia and 
Alberta to the Black Hills of South Dakota and the foot hills of 
New Mexico and California. 
Suksdorf has collected a plant in West Klickitat Co., Wash., 
which agrees perfectly with P. glandulosa, except that the petals 
are very small, obovate-spatulate and white. 
P. Hanseni Greene, Pittonia 3: 20, should perhaps be re- 
garded as a mountain variety of P. glandulosa rather than a dis-
