GILIA FAMILY I9I 



Capsule 3-celled and style 3-parted, or cells and style-branches 

 only 2 in some Navarretias. 



Leaves pinnately compound, the leaflets entire; corolla 



bluish, bell-shaped or short-funnelform 1. Polemonium. 



Leaves simple, often finely cut or deeply lobed. 



Tube of corolla constricted below the spreading lobes; two 

 stamens regularly inserted lower down than the other 



three; perennials with opposite entire leaves 2. Phlox. 



Tube of corolla not constricted below the lobes; stamens 

 often unequally inserted but not in two sets. 

 Calyx-lobes equal; flowers pediceled (pedicels very short 



in some species) 3. Gilia. 



Calyx-lobes unequal; flowers strictly sessile in heads 



with spinose bracts 4. Navarretia. 



1. POLEMONIUM. Greek Valerian. 



Perennials with alternate pinnately compound leaves, the 

 leaflets entire. Corolla bell-shaped or short-funnelform, with 

 very short tube. Stamens equally inserted near summit of 

 tube, but often of unequal length. 

 Corolla-lobes about equalling the tube. 



Stem solitary, 2 to 4 ft. tall 1. P. occidentale. 



Stems numerous, 9 in. or less high 2. P. pulcherrimum. 



Corolla-lobes much shorter than tube 3. P. eximium. 



1. P. occidentale Greene. Leaves 3 to 12 in. long; leaflets 

 9 to 25, narrowly lanceolate to ovate, 24 to \y 2 in. long. Cor- 

 olla blue, x /% in. long, much exceeded by the style. (P. coeru- 

 leum of Bot. Calif.) 



The stem of this species is strictly erect from a perennial 

 root, the upper portion bearing numerous deep-blue flowers 

 in small clusters. It grows in wet places but is known in our 

 district only from Yosemite Valley and Mono Pass. 



2. P. pulcherrimum Hook. Leaves 2 to 5 in. long; leaflets 

 7 to 19, oval or elliptic, *4 to H m - long. Corolla blue or vio- 

 let, about fg in. long, the style slightly exserted. (P. humile 

 pulchellum Gray.) 



In this Polemonium the bright flowers are borne on the 

 branching summits of leafy stems only 4 to 8 in. high, which 

 rise from a creeping, perennial base. It is found in moist or 

 shaded places at 6000 to 10,000 ft. alt., and is especially com- 

 mon along Snow Creek and at Lake Tenaya. 



3. P. eximium Greene. Leaves 1 to 4 in. long; leaflets 15 

 to numerous, crowded, elliptic, about % in. long. Corolla 

 deep blue, yi to }i in. long, the roundish lobes nearly % in. 

 across, exceeding the style. (P. confertum, of Bot. Calif.)
