POLEMONIACEAE (PHLOX FAMILY) 401 



white: style as long as the corolla; the exserted stamens inserted in the si- 

 nuses: capsule ovoid: seeds small, narrowly winged. Wyoming to New Mexico. 



12. Gilia subnuda Gray, 1. c. 276. Biennial; stems erect, simple or branched, 

 3-5 dm. high: radical leaves rosulate, oblong-spatulate, lobed or somewhat 

 pinnatifid, attenuate to the base; cauline small, bract-like, and nearly or 

 quite entire: flowers subcorymbose, terminating the branchlets, pediceled: 

 calyx glandular, as are also the pedicels, the teeth subulate, as long as the 

 narrowly campanulate tube: corolla yellow or rose-color, tubular-funnelform, 

 15-20 mm. long, minutely glandular; the lobes oval, less than half as long as 

 the tube: stamens included, nearly sessile: style glabrous: capsule ovoid: seeds 

 angled, narrowly winged, unchanged if wetted. (G. Crandallii Rydb. 1. 

 c. 634; G. Bakeri Greene, Brand, Polem.) Southern Colorado to New Mexico 

 and thence westward to Nevada. 



12a. Gilia subnuda Haydenii (Gray) Brand, 1. c. 119. Glabrate: leaves 

 deeply incised, rarely pinnatifid: corolla rose-color. (G, Haydenii Gray, 1. c. 

 11: 85.) Colorado to New Mexico. 



126. Gilia subnuda superba (Eastwood) Brand, 1. c. Viscid-glandular 

 throughout: leaves irregularly lobed or dentate: corolla orange or red. (G. 

 superba Eastwood, Zoe 4: 122. 1893.) Utah to Nevada. 



13. Gilia spicata Nutt. Journ. Acad. Nat. Sci. 2: 156. 1848. Stems rather 

 stout, erect, simple, or several from the fusiform root, 2-3 dm. high: capitate 

 flower-clusters crowded in an elongated, virgate, and spike-like thyrsus: leaves 

 thickish, almost filiform, some about 3-cleft, occasionally all entire, barely 

 mucronate: corolla salverform, purplish, 10-12 mm. long; the lobes shorter 

 than the tube: anthers subsessile in the throat: ovules 4-6 in each cell. 

 Mountains of Colorado to Utah and Wyoming. 



13a. Gilia spicata deserta A. Nels. Bull. Torr. Bot. Club 26: 132. 1899. 

 Habit of the species, but usually shorter-stemmed; stems one or more from a 

 woody root with one or more swollen crowns, lanate: basal leaves crowded 

 on the crowns, mostly simple, linear; the cauline pinnatifid, the divisions few 

 (3-5), linear, shorter than in the species: inflorescence crowded-spicate, in 

 dwarf plants approaching capitate : calyx closely and minutely glandular. 

 Desert areas in Colorado and Wyoming. 



14. Gilia cephaloidea Rydb. 1. c. 24: 293. 1897. Lanate-pubescent; stems 

 simple, solitary or several from the crown, 1-3 dm. high; root somewhat 

 woody: radical leaves crowded, linear, or 3-cleft at the apex, 5 cm. long; 

 cauline few, 3-5-cleft, the segments short, linear: corolla white: stamens 

 equally inserted in the throat, exserted, the filament and anther subequal: 

 style as long as the corolla, pilose at the apex. South Dakota to Montana 

 and Wyoming. 



15. Gilia congesta Hook. Fl. Bor. Am. 2: 75. 1838. Stems erect or spread- 

 ing, 1-3 dm. high, from a tufted base, bearing single terminal or few and 

 corymbose capituliform cymes: leaves with 2-7 mucronate divisions, or some 

 of them entire: corolla white, salverform; lobes of the corolla nearly as long 

 as the tube, which does not exceed the usually aristulate-tipped calyx-lobes: 

 exserted filaments at length as long as the anthers: ovules 1-2 in each cell: 

 capsule globose, 1-3-seeded. From the Rocky Mountains to the Pacific 

 States. 



15a. Gilia congesta iberidifolia (Benth.) Brand, 1. c. 121. Leaves more 

 rigid and the lobes cuspidate-tipped, as are also the bracts: capitate cymes 

 corymbose: filaments shorter: ovules solitary in each cell. Not readily dis- 

 tinguished from depauperate specimens of the species. (G. spergulifolia Rydb. 

 1. c. 633; G. roseata Rydb. 1. c.) Nebraska to Colorado and Wyoming. 



156. Gilia congesta crebrifolia (Nutt.) Gray, 1. c. Low, often depressed: 

 leaves crowded, all entire, linear, rigid: stems usually terminated by a single 

 capitate cluster. (G. Merrillii A. Nels. Bot. Gaz.,34: 27. 1902.) In the 

 Rocky Mountain States. 



16. Gilia polycladon Torr. Bot. Mex. Bound. 2: 146. 1859. Stems 1-2 

 dm. high, puberulent or sparsely pubescent, diffuse, very few-leaved: leaves 

 pinnatind or incised; the lobes short, oblong, abruptly spinulose-mucronate,
