GH-iA POLEMONIACEAE 461 



POLEMONIUM 



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

 filiform or capillary : calyx small ; its lobes subulate : corolla pink-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 

 spreading lobes. On wet banks, California to Washington, 



G. 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 iiliform : 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. Co- 

 rolla almost rotate, shorter than the broad and open deeply 5- 

 cleft calyx. Filaments almost naked at base. 



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

 cent : stem 3-8 inches long, diffusely much branched from the base : leaf- 

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

 broadly lanceolate lobes 2 lines long, twice as long as the broad tube; pe- 

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

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

 calyx. In moist places, California to Brit. Columbia, east of the Cas- 

 cade 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. Fila- 

 ments usually dilated and pilose-appendaged at base. 



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

 ened rootstocks : 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 

 branched above : leaflets very numerous somewhat crowded, obovate to el- 

 Ifptical, a line or two long : flowers in a small cymulose cluster ; calyx cam- 

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

 with yellow throat, 6-7 lines long, 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. 



P. humile Willd. in Rcem. & Sch. Syst. iv, 793. Somewhat pilose 

 below, pubescent above: stems rather stout, 4-8 inches high, corymbosely
