400 POLEMONIACEAE (PHLOX FAillLi) 



been proposed, only the following of which need to be mentioned. — Widely dis- 

 tributed in the western half of America. 



5a. Giliainconspicua sinuata Gray, Proc. Am. Acad. 8: 278. 1870. Nearly- 

 glabrous, the leaves sinuate: the corolla tubular to salverform. — Western part 

 of our range, and westward. 



56. Gilia inconspicua subacaulls (Rydb.) Brand, Polem. (.Pflanzenreich) 

 105. 1907. Stem low, very slender, usually branched above. (G. subacavlis 

 Rydb. 1. c. 30: 261. 1903.)— Southern Wyoming. 



6. Gilia polyantha Rydb. 1. c. 31: 634. 1904. Stem single at base but 

 branched from near the base upward; branches mostly simple and moderately 

 divaricate, almost equaling the main stem, minutely pruinose- viscid: leaves 

 2-5 cm. long, somewhat pungent, linear, entire or simple-pinnatifid, with few 

 to several linear lobes: flowers in small bracteate cymes forming narrow pan- 

 icles: calyx membranous, narrowly campanulate, about 4 mm. long, merely 

 pruinose; its teeth very short, green, triangular-subulate, and minutely pun- 

 gent: corolla white, purple-dotted, 10-12 mm. long, somewhat trumpet-shaped; 

 the tube surpassing the calyx; the lobes elliptic-oblong, acute, almost as long 

 as the tube: stamens noticeably exserted; style scarcely so: ovules about 2 

 in each cell. (G. exserta A. Nels. Bot. Gaz. 40: 65. 1905.) — Southern Col- 

 orado. 



7. Gilia longiaora(Torr.) G.Don, Gen. Syst.Gard. 4: 245. 1837. Glabrous, 

 loosely paniculate-branched: divisions of the leaves long and slender: flowers 

 somewhat corymbose on slender peduncles: corolla white, strictly salverform, 

 showy; the tube often 3-5 cm. long, with narrow orifice; lobes orbicular or 

 ovate, many times shorter than the tube: stamens unequally inserted near the 

 top of the tube, included: capsule obovate-oblong, twice as long as the calyx, 

 many-seeded: seeds angled. — ^Texas and Mexico to Nebraska and Colorado. 



8. Gilia laxiflora (Coult.) Osterh. Bull. Torr. Bot. Club 24: 51. 1897. 

 Annual, about 3 dm. high, erect, branching, glabrous except the calyx, ped- 

 icels, and growing stem, which are minutely glandular: leaves pinnate with 

 slender divisions, mucronate-tipped, the upper few-lobed or entire: inflores- 

 cence scattering, with flowers on slender pedicels 1-2 cm. long: corolla white or 

 bluish'-tinted, slender, 10-15 mm. long; the lobes ovate, pointed, 4-5 mm. long: 

 filaments included, unequally inserted: tube of the calyx 5 mm. long, with 

 subulate teeth 1.5-2 mm. long: capsule 10 mm. long, having 6 seeds in each 

 cell, which develop mucilage and spiracles when wetted.— Colorado to New 

 Mexico and Texas. 



9. Gilia aggregata (Pursh) Spreng. Syst. 1: 626. 1825. Somewhat pu- 

 bescent; stems 3-10 dm. high, leafy, sometimes loosely branching: leaves 

 thickish, with narrowly linear mucronulate divisions: panicle loose or inter- 

 rupted; the flowers sessile in small mostly short-pedunculate clusters: calyx 

 commonly glandular: corolla scarlet to pink-red, with narrow tube; the lobes 

 ovate or lanceolate, acute or acxmiinate, widely spreading, soon recurved: 

 stamens and style exserted. (Greene, in Leaflets 159 and 160, offers the i<A; 

 lowing segregates, under the proposed new generic name Callisteris: C. coUina, 

 C. formosissima, C. flavida, C. pulchella. Gilia scariosa Kydh. I. c. 31: fi32. 

 1904 is also to be referred to this species.) — ^Texas to western Nebraska and 

 west to Oregon. 



10. Gilia attenuata (Gray) A. Nels. Bull. Torr. Bot. Club 25: 278. 189S. 

 Nearly related to the preceding: basal leaves green and glabrate; the upper 

 pubescent and more or less glandular, the inflorescence decidedly so: inflores- 

 cence more narrowly thy rsif orm : calyx-lobes narrowly attenuate : corolla white, 

 the tube often pinkish, 3^4 cm. long, the lobes long and gradually acuminated: 

 style and stamens included. (G. Candida Rydb. 1. c. 28; 29. 1904; Callis- 

 teris leucantha Greene, 1. c.) — Wyoming and Colorado. 



11. Gilia pinnatifida Nutt. Gray in Proc. Am. Acad. 8: 276. 1870. Stem 

 simple or loosely branching, 1-5 dm. high: inflorescence open-paniculate, 

 often compound: leaves pinnately parted into linear or narrowly oblong lobes; 

 these sometimes again 1 or 2-lobed: stamens conspicuously exserted: corolla 

 strictly salverform, 4-5 mm. long, pale blue or violet, or the narrow tubi
