POLEMONIACEAE 



the subcylindrie tube 2 to 5 times as long as the calyx, the lobes usually laneeolate- 

 acumiuate or linear-acuminate, 4 to S^/o lines long, rotate, becoming reflexed; sta- 

 mens unequal, exserted, frequently declined, the filaments inserted in the throat 

 just below the sinuses; capsule ovoid, the cells many-seeded; seeds flat, showing 

 spiricles when wetted. 



Moist sandy flats or loose gravelly soil in opens or openly Avooded ridges, 4000 

 to 10,000 feet: North Coast Ranges from Del Norte Co. and western Siskiyou Co. 

 to Lake Co. ; Sierra Nevada from eastern Siskiyou Co. and Modoc Co. to Inyo Co. 



South to Mexico, east to Texas, Colorado and 

 Montana, north to British Columbia. June- 

 Aug. 



Field note. — Although dispersed over so vast an 

 area in western North America and growing in such 

 widely unlike habitats climatically and ecologically, 

 Gilia aggregata is an extremely constant species in 

 vegetative organs and in the character of its flowers 

 and inflorescence. Notwithstanding its wide horizon- 

 tal distribution, its altitudinal range in any one moun- 

 tain transect is, however, extremely limited. In the 

 Sierra Nevada it is common in moist flats of the Cali- 

 fornia Red Fir belt.

 Var. bridgesli Gray. Stems spreading or decumbent at base, 6 to 18 inches long, the base 

 woody; leaves often glabrate, the segments more obtuse; corolla bright rose-purple, not yellow- 

 mottled (but fading in drying and then sometimes mottled), its lobes ovate or oblong-ovate; sta- 

 mens less exserted. — Sierra Nevada from Tuolumne Co. to Tulare Co. "Inconstant except in corolla 

 color, it is different in habit from the erect form of the species. It is notable that in the southern 

 Sierra Nevada where var. bridgesii occurs on the west slope, typical Gilia aggregata is for the most 

 part found on the east slope."- — R. F. Hoover.
