Woolly dwarf sunflower as seen along Forest Road #3615, North Warner Mountains, Fremont National Forest..........June 12, 2016.
Woolly dwarf sunflower is a perennial from 50 to 100 cm in height. It is typically softly tomentose throughout, but may become glabrous with age. The basal leaves are oblong-ovate to obovate, entire, with the leaf blade from 20 to 40 cm long (See photos.). The basal leaves also have a long petiole. The stem leaves are similar but reduced in size, and have petioles with dilated bases.
The stems bear one to several sessile or short-pedunculated heads. There may be from 6 to 12 yellow rays, from 2.5 to 3.5 cm long surrounding the yellow, central disk. The involucre is 12 to 15 mm tall, with lance-oblong to ovate bracts.
Woolly dwarf sunflower is found in dry, mostly wooded slopes within its range.
Woolly dwarf sunflower is found from Lake and Klamath Counties in south-central Oregon south through Nevada and California.
