400 POLEMONIACEAE (PHLOX FAMILY) 



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

 tributed in the western half of America. 



5a. Gilia inconspicua 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 subacaulis (Rydb.) Brand, Polem. (Pflanzenreich) 

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

 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-yiscid : 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 longiflora (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 m than the tube : stamens unequally inserted near the 

 top of the tube, included :"capsule ob ovate-oblong, twice as long as the calyx, 

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



8. Gilia laxiflora (Cpult.) 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 310 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 acuminate, widely spreading, soon recurved: 

 stamens and style exserted. (Greene, in Leaflets 159 and 160, offers the fol- 

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

 C. formosissima, C. flavida, C. pulchella. Gilia scariosa Rydb. 1. c. 31: 632. 

 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. 1898. 

 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 thyrsiform: 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, 

 (jflni 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 tube
