New or NorEWOoRTHY SpeEcies.— XVI. 
THYSANOCARPUS HIRTELLUS. A foot or two in height, 
loosely branched from the base, all parts except the inflo- 
rescence and fruit clothed rather densely with short and 
rather stiffly hirsute simple hairs: lowest leaves oblanceo- 
late, coarsely toothed ; cauline triangular-lanceolate, entire, 
with rather ample sagittate-clasping basal lobes: flowers 
very minute, the narrowly spatulate petals barely equalling 
the sepals; stamens longer and well exserted: pods round- - 
obovoid, glabrous, venulose, the wing with 8 or 10 acutely n 
ovate perforations, or with as many nearly closed sinuses : 
instead (the dilated tips of the rays in this case distinct). 
Discovered by the writer in a wooded cañon tributary to — 
Dry Creek, Napa Co., California, 12 May, 1895. Very dis- 
tinct from all known species by habit and pubescence; the — 
pods also much more like those of the glabrous glaucous 
species T. crenatus and conchuliferus of the south than those — 
of T. curvipes and other northern pubescent species. 
THYSANOCARPUS EMARGINATUS. Slender and low, much : 
branched from the base, glaucous and also hispidulous, with — 
scattered, spreading or deflexed white bristly hairs: cauline 
leaves all linear-lanceolate, entire, sessile but in no degree 
auricled.or even dilated at base: flowers and radical leaves . 
unknown: pedicels of fruit short, spreading, scarcely curved: 
fruit nearly orbicular, the body glabrous, with strong mid- 2 
vein and almost equally prominent transverse veinlets, the E. 
broad wing perfectly entire, scarious, abruptly and rather ; 
deeply emarginate at apex, wholly destitute of perforations ae 
and lacking even the usual radiating bundles of fibrous - 
tissue. De
