POLEMONIACEAE. Gilia Family. 

 Herbs, or a few species slightly suffrutescent. Leaves alternate or opposite, 

 entire, lobed or divided. Flowers complete, o-morous, either solitary, in loose 

 clusters, capitate, racemose, corymbose or paniculate. Calyx persistent, in one 

 subgenus irregular. Corolla regular, convolute in the bud. Stamens 5, inserted 

 on corolla, alternate with its lobes, often unequal in length. Ovary superior, 

 3-celled ; style 3-cleft or with 3 stigmas. Capsule loculicidally 3-valved. One 

 species of Gilia has a 4-merous corolla and some exceptions as to the capsule 

 are noted under that genus. 



Calyx herbaceous throughout; filaments hairy at base; leaves alternate, pinnate 



1. POLEMONIUM. 



Calyx more or less scarious below the sinuses, at least not herbaceous throughout.

1. POLEMONIUM L. Jacob's Ladder. 



Ours perennials. Leaves alternate, pinnate, the leaflets sessile. Flowers 

 showy, bine or white, in racemes, thyrses or panicles. Calyx herbaceous through- 

 out, not scarious below the sinuses, accrescent. Corolla from funnelforni to 

 nearly rotate. Filaments more or less declined and hairy at base. Seeds few 

 or several iii each cell. (Greek name used by I boscorides, from polemos. war. 

 the application not obvious.) 



1. P. carneum Cray. Stems lax or diffusely branching, 1 to 2 ft. high; 

 herbage lightly pubescent; leaflets thin, 7 to 17, ovate to ovate-lanceolate, 1 to 

 1', in. long, distinct or the terminal sometimes confluent; flowers corymbose- 

 paniculate on rather slender pedicels; calyx about 4 lines long, accrescent in 

 age and twice as Long; corolla broadly funnelform, salmon-color to purple, s 

 to 12 lines long, the limb nearly as broad when expanded; lobes obovate and 

 either acute or obtuse; stamens and style included; seeds ,*> or 4 in each cell.
