CONTRIBUTIONS TO WESTERN BOTANY No. 17 25 
They should be fleshy when mature. The flowers are very narrowly pear- 
shaped, short-stiped, white with linear and blue-striped seg (perianth), 
with tips spreading. The stipe is 14 inch long as in Samucla. The species 
can always be separated from Mohavensis by the p 
olina Texana ? This comes in along is road in the upper edge of 
the juniper belt, west of Williams, on dry knolls. The panicles are 3 to 6 
feet long and with short peducle at base, very different from N. Bigelovii 
at Oatman, which was also in full bloom. 
Caulanthus annuus. N. Sp. Annuals, 2-3 feet high and erect. Racemosely 
branching above, and with the branches terminating in a naked raceme 
about a foot long in fruit, but flowers inclined to be capitate at first. All 
the leaves sessile and clasping but not perfoliate, entire, rounded at both 
ends, the lowest inclined to be obovate-elliptical, the middle ones elliptical- 
oblong and the uppermost ovate-elliptical, about 3 inches long, flat, the upper 
somewhat reduced, the internodes somewhat shorter than the leaves. Flowers 
bractless, narrow, nearly half an inch long, with linear and slightly saccate 
bases, and tips inclined to spread, and purplish, thin petals nearly white, flat, 
linear-spatulate, entire, a little longer than the sepals, very thin, and a little 
longer than the linear and sagittate and twisted anthers. Pods on stout and 
ascending pedicels half an inch long and which are 1-2 inches apart. Pods 
inclined to be tetrangular, 2mm. wide and 5-6 inches long, indifferently as- 
cending, and rather lax, with a stout beak 1-2 mm. long, whole plant smooth. 
Leaves inclined to be ‘palmately veined below. Growing in waste places 
on slopes in the pine forests. Middle Temperate life zone, cies Canon City, 
Oregon. The plant has the habit of Streptanthus orbicular 
Lepidium montanum Nutt. This species as ‘adit audersuct is a 
hodge-podge. The type is described as having elliptical pods, which is a 
character of the plants growing around Grand Junction, Colorado, and which 
seem to pass into L. alyssoides and have a short style. The majority of the 
material from the north (Wyo. to Oregon) and south at least to central 
Utah, has cordate-ovate pods, reticulate pitted, distinctly stipitate, and with 
style half as long as the pod, and top of pedicel somewhat winged. This 
would come between L. Cradallii Rydberg and L. papilliferum (Hend.) 
Nels McB., both = which seem to be spurious species. It is unfortunate 
that we cannot use either proposed species as a variety of L. montanum, 
though Crandallii i is nearer than the other but founded on a pod too long and 
without the rugose sides. L. papilliferum is described as having orbicular 
pods and short style. Now the form of this species ( prema common 
in northern Nevada, is striking and quite different from typica mtanum. 
There is a great variability i in the length of style, from not Gace en the 
notch to Imm. long. But the same re habit, being a short-lived peren- 
nial. Collectors have confused forms of L. medium Greene with this species 
from the north. I doubt if any ei of alyssoides occur anywhere in the 
north, with which nee have confused the same species (L. medium). 
Stanleya annua N. Sp. No. 25317, Stems annual, erect, 2-4 feet high 
and simple, not seals nor winged, glauous and smooth throughout. Leaves
