POLEMONIACEAE 



fuimelform, 4 to 5 lines long, its lobes ovate to oblong; stamens a little exserted from 

 corolla-throat. 



Open hillslopes and valleys, 25 to 2500 (or 7700) feet: Sierra Nevada from 

 Plumas Co. to Kern Co. ; Great Valley; Tehachapi Mts.; South Coast Ranges from 

 Contra Costa Co. to San Luis Obispo Co. ; western Mohave Desert ; cismontane 

 Southern California. South to Lower California. Apr.-May. 



Tax. note. — As here formally set down, the ranges of GUia staminea and Gilia capitata are 

 indicated as if mutually exclusive, a situation not wholly true, but true to a significant degree. 

 There is some slight or occasional overlapping, and intermediate individuals are also found. In 

 the central and southern Sierra Nevada many collections occur which, though in the main referred 

 to Gilia staminea, often verge towards Gilia capitata. In the South Coast Range territory of 

 GUia staminea, infrequent colonies appear which approach Gilia capitata closely. Considering 

 the entire range of either species, such intermediates are, however, relatively few; typical indi- 

 viduals of either species occur only -vvithin the main range of its species. Exceptions are few: for 

 example, Jepson, 15,080, which is tj-pical Gilia staminea, is found in Weldon Canon, Vaca Mts., 



that is, in the North Coast Range territory 

 of Gilia capitata. 



The flower heads in GUia staminea are 

 usually larger than in Gilia capitata. They 

 are sometimes quite spherical but frequently 

 loose and irregular and (as it were) 2 or 

 3-lobed. Sometimes the heads of Gilia sta- 

 minea, in association with free branching, 

 break up into numerous very small or few- 

 flowered heads. While not invariable, the 

 breadth of the corolla-lobes is the most satis- 

 factory differentiating character as between 

 these two species. In California Gilia sta- 

 minea is more widely distributed than Gilia 

 capitata and is distinctly more variable. The 

 following are cited as Gilia staminea.

 divaricately branched or simple, arising from a basal or sub-basal dense tuft of 

 leaves; herbage conspicuously glandular; leaves 1 to 31/2 inches long, bipinnate, the 

 narrowly linear or filiform divisions spreading or curving; flowers densely capitate, 

 the heads spherical, 3,4 to 1% inches broad ; pedicels densely long-woolly, the calj^ces 

 less so ; calyx inflated, somewhat accrescent and therefore not usuall.y ruptured in 

 fruit, the hyaline intervals very full ; corolla deep blue, funnelform, 4 to 5 (or 7) 

 lines long, 4 to 5 lines wide; stamens conspicuously exserted, the filaments inserted 

 in the corolla-sinuses; anthers pale blue.
