4. P. stansbur5d Hel. Stems several to mauy, erect from a woody base, 3 to 

 12 iuches high; herbage puberulent or short-villous, usually glandular, sometimes 

 partially glabrous; leaf-blades linear or linear-lanceolate, thick, i/^ to 1^/2 inches 

 long ; flowers iu a terminal corymbose cyme; calyx 4 to 5 lines long, the lobes broadly 

 subulate, % as long as tube; corolla pink or white, its tube 7 to 11 lines long (I14 

 to 2 times as long as caljrs), with a hairy ring at base inside, its lobes bi'oadly ob- 

 ovate, entire or retuse, about half as long as the tube; stamens unequal, the 2 of 

 higher insertion slightly exserted; stj'le longer than calyx, nearly as long as corolla- 

 tube; ovary-cells 1-ovuled. 



Gravelly soil iu desert ranges, 4000 to 9900 feet : Mohave Desert; Inyo and Mono 

 Cos. ; Modoc Co. East to New Mexico, Utah and Wyoming, north to Washington.

Field note. — Phlox stansburyi often climbs by means of other plants. Long slender almost 

 filiform stems, growing up through Artemisia tridentata bushes, characterize this species in the 

 Virginia Lakes region of Mono County; stems so slender and weak that it is impracticable to dis- 

 entangle them without breaking. The flowers and rather scanty leaves are at the top of the bushes, 

 two feet above the ground. — F. W. Peirson.

Note on variation. — Phlox stansburyi is a variable species in the matter of habit, size of corolla 

 and relative length of corolla and calyx. A considerable range of variation may even appear in 

 one collection; it may sometimes appear, as to the flower, in a single individual. These variables 

 are markedly reflected in its low compact var. brevifolia, into which it insensibly passes. In var. 

 brevifolia the corolla-tube slightly exceeds the calyx or varies to twice as long. The style varies 

 in length from 1 to 1% times as long as the calyx. Usually the style varies with the corolla, but 

 sometimes the style varies independently of variation in the corolla.
