NEW OR NOTEWORTHY SPECIES. 227 
STREPTANTHUS ARGUTUS. Perennial, stout, erect, 1 to 14 
feet high, rather succulent, glabrous, glaucous: tufted rad- 
ical leaves 2 inches long, spatulate, very obtuse, saliently 
and sharply dentate, the teeth in some verging towards the 
serrate, occasionally runcinate, the cauline few and mostly 
in the form of oblong-ovate cordate-clasping bracts an inch 
long or more and entire or the rounded apex toothed: 
flowers not well known, but white, the sepals not bristle- 
tipped : pods in a loose raceme, ascending or suberect, 2 or 
3 inches long, 14 lines wide, merely mucronate by the sub- 
sessile stigma: seeds suborbicular, winged. 
Native of mountain parks in middle and southern Colo- 
rado, where it has been collected and distributed rather ex- 
tensively by H. N. Patterson as S. cordatus, and more recently 
by Miss Eastwood, under the same name. 
STREPTANTHUS CRASSIFOLIUS. Perennial, but taller and 
more slender than the last, glabrous, glaucous: lowest leaves 
tufted, 2 or 3 inches long including the obovate serrate or 
dentate blade and narrowly winged petiole, the few cauline 
sessile, lanceolate-cordate, entire, 1 or 2 inches long: raceme 
long and loose, the large oblong-ovoid calyx purple, the 
sepals with a tuft of short bristles at tip; narrow limb 
of petals dark purple; anthers of the longer pair of stamens 
partly exserted, the others included: ascending pods 2 or 3 
inches long, only a line wide, slightly torulose, somewhat 
rostrate-acuminate: seeds oval, winged, but the wing broad 
around the summit of the seed, and narrowed toward the 
funiculus, , 
Frequent in the mountain districts of eastern California 
southward, and in adjacent Nevada and Arizona. The great 
bulk of all that is in the herbaria as “S. cordatus” is this 
Species; for it has an extended range, and has often been 
collected. 
SrREPTANTHUS corpatus, Nutt. T. & G. Fl. i. 77. Of this 
Species no type specimen is known to be extant; and only
