 puberulent, diffusely much branched, G to IS inches high : leaves an inch long or 

 less : flowers half a line long, mostly near the ends of the branches : capsule oblong, 



2 or 3 lines long, on pedicels of about the same length or shorter, often deflexed, 

 3-5-seeded. — Fl. i. 513; Watson, Bot. King Rep. 105. 



From Oregon to Mariposa Co. and eastward to Colorado, in the mountains on dry slopes.

 short appressed pubescence, 6 to 18 inches high, the elongated branches mostly 

 simple: flowers half a line long, axillary the whole length of the branches: capsules 

 linear, sessile or very shortly pedicelled, <S to 10 lines long, usually many-seeded. —

From the < 'olumhia River to Central California and eastward to Colorado. 



3. Gr. diffusum, Torr. & Gray, I.e. Nearly glabrous, G to IS inches high: 

 flowers larger, \\ to 3 lines broad, mostly toward the ends of the branches : capsules 



3 to G lines long, a little exceeding the pedicels, often deflexed, the cells 4 - 8-seeded.
