190 PITTONIA. 
Mountains of eastern Washington, collected by Suksdorf, 
in 1884 and 1885, and also in northeastern California, Mrs. 
Austin, 1894. Species well marked in character, and with 
the narrowest of pods; the whole plant being very slender. 
* A. CONSANGUINEA. Stems solitary, or several from as 
many branches of the caudex, erect, simple or somewhat 
branched as to the inflorescence, 10 to 16 inches high, 
stoutish, lowest leaves about an inch long including the 
oblanceolate serrate-toothed blade and narrow petiole, can- 
escently stellate-tomentose without other pubescence, the 
lower cauline nearly as long, spatulate-lanceolate, dentate, 
sessile but scarcely auricled, the uppermost oblong, often 
entire, auriculate-clasping, these stellate-hairy only beneath, 
all the lower equally so on both faces: racemes rather short, 
the rachis occasionally and the pedicels usually stellate- 
pubescent: flowers about 14 lines long: sepals stellate- 
hispidulous, also usually the young ovaries: petals erect, 
oblong, pinkish: anthers oblong-linear, auriculate at base 
but not sagittate: pods narrow, nearly straight, moderately 
deflexed on curved pedicels, but not refracted; the valves 
l-nerved: seeds distinctly biserial. 
Obtained at Los Pinos, southern Colorado, 18 May, 
1899, by C. F. Baker. 
“A. ARIDA. Perennial, the several stoutish rigid stems 
about a foot high, the whole plant even to the pods hoary 
with a white pubescence chiefly low and stellate, but in 
part consisting of longer and divaricately forked hairs: 
lowest leaves oblanceolate, petiolate, dentate; cauline ob- 
long, entire, sessile by an auricled base: flowers not known: 
pods deflected on very short pedicels, purplish but rather 
densely stellate-tomentulose, rather broad and obtuse, the 
stigma sessile: seeds in one row.
