Townsendia nuttallii Dorn 



Nuttall's daisy 



DESCRIPTION: Nuttall's daisy is a small, cushion-forming, 

 stemless perennial from a taproot and branched rootcrown. The 

 clustered basal leaves are narrow and linear, but they expand 

 into a small spoon-like tip. They are 5-20 mm long, and 1-3 mm 

 wide with entire margins. Foliage is densely covered with long, 

 straight, silvery hairs. Flower heads are borne among the basal 

 leaves. Each head has 3-4 series of narrow, pointed, green and 

 hairy involucral bracts, 4-9 mm long. The white to (more 

 commonly) lavender ray flowers are ca. 8 mm long, and the yellow 

 disk corollas are 4-5 mm long. The flattened, lance-shaped seeds 

 (achenes) have only a few scattered hairs when mature and are 

 topped by straight, stiff bristles (pappus) ca. 5-6 mm long in 

 disk flowers and ca. 0.5 mm long in ray flowers. 



Townsendia nuttallii is very similar to T. hookeri , but the 

 latter has achenes that are hairy when mature and pappus of both 

 ray and disk flowers is long. Townsendia hookeri always has 

 linear leaves that do not expand near the tip.
