4. Polemonium filicinum Greene. 



Stems solitary or few, stout, to 4 dm. long or more, with numerous leaves, gla- 

 brous or nearly so toward base, sparsely pubescent above; leaflets lanceolate (usu- 

 ally narrowly so), acute to acuminate, to 2.5 cm. long, thin, the uppermost ones 

 decurrent and confluent, not appearing verticillate; inflorescence several- to many- 

 flowered, narrowly thyrsiform, somewhat viscid; corolla funnelform-campanulate 

 to rotate-campanulate, 1.2-2 cm. long, the acutish lobes violet and longer than the 

 tube and throat. 



In wet soils along streams and in springy places, in N.M. (Lincoln, Otero and 

 Sierra cos.) and Ariz. (Apache, Greenlee and Cochise cos.), July-Sept. 



3. Gilia R. & P. 



Perennials, biennials or annuals; leaves alternate, borne mainly below midstem, 

 pinnately toothed or dissected, the segments herbaceous or rarely subacerose; flowers 

 in bracted glomerules, unevenly paired or solitary, terminating paniculately dis- 

 posed branches; sepals partly united, separated and bordered by scarious mem- 

 branes; petals violet-blue to lavender, often with yellow throat, partly united to 

 a regular rotate to funnel-salverform corolla; stamens even to moderately uneven; 

 seeds viscid when wet. 



About 60 species in western North America and South America. 



1. Leaves linear in outline, pinnatifid with numerous linear or narrowly oblong 

 segments 3-8 mm. long; inflorescence an open panicle; stems strict 

 1. G. calcarea. 



1. Leaves with several narrowly lanceolate lobes; inflorescence 2- to 6-flowered 

 glomerules; stems often decumbent 2. G. gilioides. 



1. Gilia calcarea M. E. Jones. Fig. 645. 



Biennial or perennial; stems 1-5 dm. tall, usually single from a taproot, simple or 

 branching above the base, erect, glandular-puberulent and often viscid; leaves 

 mainly in a basal rosette, pinnatifid into linear or narrowly oblong segments 3-8 

 mm. long, glandular; inflorescence open-paniculate, often compound from branches 

 bearing flowers; calyx 2-3 mm. long, glandular, united for two thirds or more of 

 its length, scarious below the sinuses, the lobes with a green midrib: corolla 6-9 

 mm. long, blue to purplish or sometimes whitish, salverform, the often yellowish 

 tube about twice as long as the calyx; stamens conspicuously exserted. G. pinnati- 

 fida Nutt., not M09. & Sesse, C. viscida Woot. & Standi. 



In wet meadows and on gravel bars along streams in N. M. (Taos, Santa Fe, 

 and Bernalillo cos.), July-Sept.; Neb. and Wyo., s. to N.M. 



2. Gilia gilioides (Benth.) Greene. Straggling Gilia. 



Erect or decumbent annual, often very much loosely branched, sometimes simple, 

 villous to glandular-viscid; lower leaves 2-7 cm. long, sometimes in a basal tuft, 

 3- to 9-lobed, the lobes narrowly lanceolate and entire or irregularly toothed; 

 cauline leaves 3- or 5-lobed, the terminal elongate, the lanceolate lobes entire or 

 irregularly toothed; inflorescence composed of glomerules of 2 to 6 flowers, either 

 terminal or on short lateral branchlets; pedicels 2-5 mm. long, often elongating 

 with the growing capsule; calyx 3-4 mm. long, the linear lobes acuminate, the 

 membranous pseudotube about one half the calyx length; corolla 5-10 mm. long, 

 about 2 times the calyx length, the tube and throat continuous and 6 mm. long, 

 the lobes 2-2.5 mm. long; capsules 3-4 mm. long, the locules usually 1 -seeded or 

 rarely 2-seeded. 



In moist or wet soil along streams in Ariz. (Gila and Yavapai to Pima cos.), 

 Mar.-May; Ore. to Nev., Ariz, and Calif.
