PHACELIA RUPESTRIS. Perennial with habit of P. ramosts- 
sima, but stems low, slender, very fragile, and with the leaves, 
velvety with a dense short pubescence, that of stem and branches 
spreading, of the leaves appressed: racemes 3 to 5, short and 
crowded : corollas small, whitish: sepals of the small fruiting 
calyx nearly linear, exceeding by one-third the small round- 
ovoid acute 4-seeded capsule.

LAPPULA LEUCANTHA. Perennial, 2 feet high, loosely race- 
mose from near the middle: lowest leaves not seen, those of the 
stem oblong and linear-oblong, obtuse, narrowed toa subpetiolar 
base, thin, green, very rough with short mostly appressed 
bristly hairs from a pustulate base: racemes long, slender, 
widely spreading: corolla rather large, 4 lines wide, white; 
back of nutlet ovate, muriculate, surrounded by a short border 
of alternately large and small flat glochidiate prickles, all of

PHLOX MESOLEUCA. Perennial, slender, 5 to 10 inches high, 
the mostly simple stems from horizontal rootstocks not deeply 
seated : herbage pale, not viscid, merely glandular-puberulent 
or finely pubescent: leaves 2 or 3 inches long, narrowly linear, 
widely spreading or recurved, the internodes 4 to 2 inches long: 
flowers 2 or 3 only ; calyx 3 inch long, its teeth as long as the 
tube, subulate-linear ending in a long slender spinescent tip, the 
whole calyx glandular-hirtellous: corolla-tube barely equalling 
the calyx, the limb 14 inches wide, lilac with large white center ; 
lobes entire, obtuse, round-obovate to nearly orbicular, broadly

Dry foothills of the Black Range, New Mexico, at 6,600 feet, 
29 June, 1904, O. B. Metcalfe, n. 1272. 
The above name was suggested by the color of specimens 
newly dried ; but now, after a year and more, they are faded to 
white.
