59. G. INCISA, Benth. Annual, minutely puberulent or glabrous, slender, 1-2*^ high, effusely pan- 
icled ; lower leaves lyrate, the upper narrower and incised or toothed, on the branchlets nearly linear 
and entire; pedicels filiform, rigid ; corolla rotate, almost 5-parted, the slender filaments inserted nearly 
in the sinuses ; cells many-ovuled. — E. Texas to Mexico. 
60. G. RIGIDULA, Benth. Perennial, glabrous or viscid-glandular, diffusely branched, a span high ; 
leaves pinnately or the upper nearly palmately parted, the lobes lanceolate, linear or slender-subulate; 
corolla 9-16" broad, blue, rotate, 5-parted, with broad obovate lobes ; filaments slender, inserted in the 
sinnses; anthers linear or elongated-oblong ; cells several-ovuled. — Texas to Arizona and Mexico. 
POLEMONIUM. 
$ 1. Corolla funnelform, exceeding the calyx, the tube usually elongated ; filaments barely hairy and 
scarcely dilated at base. Viscid-glandular musk-scented dwarf perennials, with creeping root- 
stocks and very small and numerous crowded leaflets. 
L P. CO.NFEKTUM, Gray. Tufted ; leaflets 3-5-cleft, segments round-oval to linear-oblong ; flowers 
clusteri d, noiidiug, looser in fruit ; calyx-tube twice longer than the narrow-lobes ; corolla-tube exceed- 
ing the calyx and 2-4 times longer than its own rounded lobes. See page 271, 
2. P. vi.'^cosr.M, Nutt. More dwarf; leaflets entire, ovate or rounded, long; flowers looser, 
subcorymbcd ; calyx .siibcampunulate, lobes broadish, equaling the tube ; corolla-tube equaling the calyx, 
not exceeding its own lobes. — N. Colorado, (Xuttall.) 
$2. Corolla rotate-campanulate, moderately exceeding the calyx; filaments dilated at base. Per- 
ennials, with laxer infloreseuce ; leaflets entire, the upper often confluent. 
3. P. c.Ei:ri;i-,r>r, L. l-?,- high, leafy ; flowers numerous; calyx cleft to the middle; stamens or 
style usually exsert ; cells 7-12-()vuled, several-seeded. See page 272. 
4. P. HCMiLK, Willd. Pubescent, mostly glandular; stems a span high, 1-2-leaved ; flowers few, 
subcorymbed, ratlier long i.eilicelle.l ; ralyx cleft beyond the middle; cells 2-4-ovuled, 1-2-seeded.— 
Arctie Auieriea and Alaska, and southward in the mountains to Colorado and California.
