 fasciculatis copiose ramosis et a basi patentibus crassioribus 

 6-12 cm. altis; foliis crassioribus inferioribus lato-oblanceolatis 

 acutis sessilibus vel interdum alato-petiolatis 4-8 cm. longis, 

 superioribus angustioribus multoque minoribus; floribus multis, 

 pedicellis 6-12 mm. longis post inflorescentia abrupte reflexis; 

 calyce cylindrato 12-15 mm. longo lobis triangularis actuis 4-7 

 mm. longis; petalis pallentirubris vel albidis quam calyce 1 cm. 

 longioribus, lamina aut profunde 4-lobata et lobis mediis multo 

 longioribus aut 2-lobatis et eis solum dentatis, squamis coronae 

 integerrimis, auriculis obsolitis; capsulis fere globosis calycem 

 valde distendentibus 7-8 mm. longis stipe 2 mm. longo; semini- 

 bus crasso-papillosis. — Type Peck 14975, on a dry sandy slope, 

 2 mi. north of Central Point, Jackson County, June 18, 1927. 



This is most nearly related to S. Hookeri Nutt. from which 

 it is distinguished by its lower, more condensed habit, and es- 

 pecially by the very viscid character of the pubescence. The 

 specific name is suggested by the fact that the glandular foliage 

 is usually found thickly covered with dust. It has been collected 

 several times in eastern Josephine and western Jackson Coun- 

 ties.

 mm. longo; seminibus universe tuberculatis valdius tergo. — 

 Type Peck 16513, from bluffs above the sea at the mouth of 

 Salmon River, Tillamook County, August 10, 1930. 



The relationship of this species to S. Donglasii Hook, is un- 

 doubtedly close; it may be distinguished, however, by the elon- 

 gated rootstocks, more numerous and broader cauline leaves, 

 more strongly inflated and membranous calyx and larger petals.
