high; pod globose or a little elongated, stellate-pubescent with a long style, pedicels 
recurved as in L. ludoviciana, which it resembles, although it is more slender and 
more branched and has smaller pods. 
Hillside, Hot Springs, altitude 1,100 m., June 11 and August 3 (No. 533). 
Lesquerella spatulata sp. nov. 
Low and somewhat ciespitose; stems 3 to 10 em, high, subscapose; leaves all radi- 
cal, spatulate or oblanceolate, decurrent on the petiole; petals spatulate, yellow ; 
pods on recurved pedicels, ovate, only slightly compressed toward the apex, finely 
pubescent, 4-seeded; septum not perforate; style scarcely as long as the mature 
pod. ° 
Like the last in habit, but lower. The pod, however, is ovate, pointed, and 
slightly compressed toward the apex, about the length of the slender style but 
shorter than the pedicel, which is retlexed and then curved upward, The plant is 
somewhat intermediate between L. montana, the preceding species, and L. alpina. 
From L. montana it differs in its more slender habit, narrower leaves, and smaller 
pods; from L. alpina, in being much taller and in having broader leaves, less com- 
pressed pods, longer and recurved pedicels, and shorter style. In L. alpina the style 
is longer than the pod, the pedicels erect, and the septum perforated. . It differs 
from L. argentea arenosa in the form of the pod. Similar specimens were found in 
the Harvard Herbarium, viz, in C. C. Parry's collection of 1873 (No. 21) and in the 
collection of Jenney’s expedition, 1875. These were referred to L. alpina by Dr. 
Watson. In the Columbia College herbarium there are the following specimens: 
H. J. Webber, from Belmont, Nebraska, 1889; Dawson, Milk River, N. W. T., 1883. 
Dry hilltop, north of Deadwood, altitude 1,600 m., July 5 (No. 534), 
Camelina sativa (L.) Crantz, Stirp. Austr. i, 18 (1762); Wyagraum sativum L. Sp. 
Pl. ii, 641 (1753). 
Introduced: Railroad embankment above Custer, altitude 1,700 a., July 15

Bursa bursa-pastoris (L.) Weber in Wigy. Prim. Fl, Holst. 41 (1780); Thlaspi bur- 
sapastoris L. Sp. Pl. ii, 647 (1753). 
The common form was collected in yards at Custer, altitude 1,625 m., June 4 
(No. 536). 
The so-called variety integrifolia, that is, the form with entire leaves, was collected 
on a hillside near Central City, altitude 1,700 m., July 3 (No.587), 
A delicate form was found with finely pinnatifid leaves; the divisions oblong, 
sometimes sinuately toothed; pods (immature) broadly oval, sometimes truncate, 
but not at all triangular. The general appearance reminds one somewhat of Tees- 
dalia nudicaulis. Hillside, south of Custer, altitude 1,625 m., May 28 (No. 538).
