192 GILIA FAMILY 



leaflets, at once mark this interesting Alpine plant. The leaves 

 are crowded toward the thick, perennial base, the flowering 

 stalks (2 to 8 in. high) being comparatively naked. The flowers 

 are in terminal, head-like clusters. The species grows only 

 among granite rocks above timber-line but here it is common, 

 from one end of the Sierra Nevada to the other, amid sur- 

 roundings such as shown in the illustration. 



2. PHL(5X. 



Low perennials with opposite and sessile entire leaves. 

 Corolla with a long slender tube and abruptly spreading 

 limb (salverform). Stamens included, very unequally in- 

 serted in the tube of the corolla in two sets. Capsule with but 

 1 seed in each cell. 



Leaves 1 or 2 in. long; corolla-lobes usually notched 1. P. speciosa. 



Leaves Yz in. or less long; corolla-lobes entire. 



Leaves % to l / 2 in. long 2. P. douglasii. 



Leaves not J4 in. long; calyx glandular 3. P. caespitosa. 



1. P. speciosa Pursh. Leaves not crowded, 1 to 2 x / 2 in. 

 long, linear-lanceolate, acute. Flowers in loose clusters, the 

 naked calyx (and stems) glandular-hairy. Corolla rose-pink, 

 y 2 in. across, the lobes deeply notched or sometimes entire, 

 the tube r / 2 in. long. 



This is one of the most showy and pleasing plants of the 

 lower part of the pine belt. The loosely branched, woody 

 stems are 6 to 18 in. high and bear a great profusion of dainty, 

 pinkish flowers. The species is not common except in the 

 neighborhood of Crockers and in Tuolumne Co. Our form, 

 marked by the glandular calyx with teeth shorter than the 

 tube, was once called P. occidentalis Dur. 



2. P. douglasii Hook. Leaves densely crowded, % to J / 2 in. 

 long, nearly awl-shaped, sharply pointed. 

 Flowers terminal on short branches, the 

 calyx crisp-hairy and nearly hidden by the 

 upper leaves. Corolla bluish purple, lilac, 

 or nearly white, Y% to Y$ in. across, the tube 

 (y 2 in. long) exceeding the calyx, the lobes 

 entire. 



The very leafy stems of this Phlox creep 

 along the ground, forming dense, green 

 mats, thickly dotted with beautiful flowers 

 on erect branchlets. It grows on gravelly slopes and sum- 

 mits above 6000 ft. alt. The comparatively loose form with 

 longer leaves is the var. diffusa Gray.
