Slender (20 cm. Iiigli)i entirely glabrous, apparently slightly 

 fleshy : leav^cs mostly radical (8— 12 cm. x 2 cm.), narrowly ob- 

 long, pinnately nicised and parted and somewhat lyrate ; divisions 

 decurrent, oblong or more commonly obovate-cuneate, incisely 

 toothed above, terminal portion of the leaf not enlarged, petioles 

 as long as the blade, slender; cauline leaves 3-4, much smaller, 

 upper quite small and with distant linear (6-8 mm. long) divi- 

 sions : heads several in a capitate corymb, small (7 mm. higli), 

 on slender glabrous bracted pedicels : involucre narrowly cam- 

 panulate ; bracts 10-12, hnear-lanceolate, thin, mostly acute, 

 l-2-nerved and green, whiter on the margins but scarcely scarious, 

 calyculate outer bracts usually wanting : ray flowers only 2 or 4, 

 longer than the disk, bright orange : achenes obovate, truncate, 

 glabrous; pappus copious, white: tu|)e of the corolla slender; 

 limb elliptic (8 mm. long), the rounded apex 3-4-toothcd : style 

 slender : stigmas scarcely truncate : disk flowers numerous, orange : 

 achenes and pappus same as in the ray flowers : corolla slender, 

 evenly funnel-form, narrow, glabrous; lobes 5, acute: stamen- 

 tube rather short, ape:^ of the stamens obtuse, cubical tissue of the

Loose stones and gravel near the headwaters of the Quilcene 



river, Olympic Mountains. 



This species belongs to the group represented by ^. Bolanderi 



Gray, vS'. lactifloms Greene, and S, indcconis Greene, but differs 

 from the known species In its peculiarly lobed leaves, naked stem, 

 and small glabrous heads. The early root leaves in some cases 

 show a tendency to become orbicular and merely crenate.
