7. S. radiata Ktze. Giant Deer Tongue. 

 Plants 2 to 6 feet high; stem very stout, erect, 

 single from the stout taproot ; herbage very mi- 

 nutely puberulent; leaf -blades oblong-oblance- 

 olate (or narrowly oblong or obovate), acute, 9 

 to 13-nerved, 5 to 11 (or 15) inches long, scarcely 

 petioled; stem-leaves in whorls of 3 to 7; panicle 

 narrow, 1 to 2 feet long; flowers on pedicels 1 to 

 2V2 inches long; corolla greenish-white, purple- 

 dotted, 1 to 114 inches wide, its lobes ovate, acute, 

 each with fringed or laciniate appendages at 

 base; glands 2 to each lobe, narrowly oblong, 

 long-fringed all around; crown at the base of the 

 lobes cut into setaceous segments which reach to 

 the middle or summit of the glands; capsule 8 

 to 9 lines long, ovate, flattened contrary to the 

 valves, which are boat-shaped. 



Open coniferous woods, 7000 to 9000 (or 

 10,100) feet : Sierra Nevada from Fresno Co. to 

 Eldorado Co.; North Coast Ranges from Mendo- 

 cino Co. to Siskiyou Co. North to Washington, 

 east to the Rocky Mts. June-July. 



Field note. — ^With its tall unbranched main axis rising from a ground rosette of large leaves 

 and often flowering from near the base, this species is a striking feature of the forest where it 

 occurs. WhUe widely distributed, it is seldom met with and the plants are few in a colony and 

 usually solitary. A record of plants found together in numbers has been made by F. W. Peirson 

 who observed in 1935 a scattering colony of twenty or thirty individuals along the stream below 

 Moat Lake in the Virginia Lakes region, Mono Co., at an altitude of 10,100 feet. In open country, 

 with low chaparral or none, here at this spot was an exceptionally fine display, the individuals 

 imposing in appearance.
