210 POLEMOXIACEAE 



Peak, Lassen Co., Jepscm 7814; Forestdale, sw. Modoc Co., M. S. Baker; Big Bear Flat, se. Sis- 

 kivou Co., Jepsoji 20,115. 



Var. septentrionalis (Mason) Jepsou & Bailey comb. n. Corolla 1 to 2 lines long, the throat 

 usually with a ring of fine pubescence at insertion of stamens; capsule-cells 2 to 5-see(led. — Mono 

 Co. (betw. Mono Lake and Bridgeport, Keel- 2914). East to Nevada and Wyoming, north to 

 Montana, Idaho and eastern Oregon. Plants of var. septentrionalis from a wide range are uniform 

 in character and are like Linanthus harknessii in habit, aspect, hue, leafage and inflorescence and 

 essentially in flowers. The variety differs from the species most reliably in the number of seeds 

 in the capsule.
