POLEMONIUM POLEMONIACE.E 461 



icle : leaves 6-20 lines long or the uppermost reduced to small subulate 

 bracts, entire or the lower sometimes with 2 or 3 small lobes: peduncles 

 filiform or capillary : calyx small; its lobes subulate: corolla p nk-red, 5-10 

 lines long; its slender tube longer than the calyx, and rather abruptly 

 expanded into a wide funnelform throat of about the length of the oval 

 f-preading lobes. On wet banks, California to Washington. 



6. linearifolia. Minutely glandular: stem slender, 6-12 inches high, 

 branching into an effuse panicle : leaves linear, 6-12 lines long, attenuate 

 at both ends: peduncles filiform: calyx a line long, with short-oblong 

 triangular-pointed lobes : corolla with a slender tube longer than the calyx, 

 gradually expanded into a funnelform throat of about the length of the 

 oblong lobes. In moist places, southern Oregon. 



8 POLEMONIUM Tourn. Inst. 146, t. 61. 



Herbs with alternate pinnate or pinnately parted leaves, and 

 mostly showy flowers in cymose panicles, or racemes, or thyrsi- 

 form. Calyx herbaceous throughout, neither angled nor costate, 

 slightly accrescent and loosely investing the capsule, campanu- 

 late or narrower, cleft to the middle, the lobes equal, erect or 

 connivent over the capsule, or campanulate-spreading, entire. 

 Corolla regular, from funnelform to nearly rotate. Filaments 

 more or less declined, and usually pilose-appendaged at base, 

 slender. Ovules few or several in each cell. Seeds angular or 

 winged, developing mucilage when wetted. 



1 Root annual. Flowers solitary, opposite the leaves. 

 Corolla almost rotate, shorter than the broad and open deeply 

 5-cleft calyx. Filaments almost naked at base. 



P. inicrantha Benth. DC. Prodr. ix, 318. More or less viscid-pubes- 

 cent : stem 2-8 inches long, diffusely much branched from the base : leaflets 

 5-13, obovate to lanceolate, 2-4 lines long : calyx truncate at base, the broad- 

 ly lanceolate lobes 2 lines long, twice as long as the broad tube: peduncles 

 mostly solitary, opposite the leaves or terminal: corolla white, a line or 

 two long : ovules 1-3 in each cell : capsule globose, shorter than the calyx. 

 In moist places, California to Brit. Columbia, east of the Cascade Mts. 



2 Root perennial. Leaflets simple and entire, sometimes 

 confluent. Inflorescence open and with very few bracts. Corolla 

 campanulate-funnelform with tube not surpassing the open-cam- 

 panulate calyx, and shorter than the ample spreading limb. 

 Filaments usually dilated and pilose-appendaged at base. 



* Stem 6-10 inches high, from cespitose-branching and mostly 

 thickened rootatocks : leaflets seldom 6 lines long: flowering stems 

 only 1-3-leaved: flowers cymulose. 



P. elegans Greene Pitt, iii, 305. Very viscid -pubescent throughout 

 except the corolla : stems slender, 2-6 inches high ; simple or sparingly bran- 

 ched above : leaflets very numerous somewhat crowded, obovate to elliptical, 

 a line or two long: flowers in a small cymulose cluster; calyx campanulate, 

 cleft to the middle, with broadly lanceolate lobes : corolla blue with yellow 

 throat, 6-7 lineslong, the broadly obovate lobes equalling the tube : filaments 

 pilose at base : style barely exserted : capsule ovoid, much shorter than the 

 calyx, few-seeded. On Mount Adams Washington near perpetual snow.
