 and also, in its smaller form, Kriyia Viryinim. Like these the foliage is very variable. Involu- 

 cre from 6 to 9 lines high ; the outer scales sometimes more foliaceous. Akenes 2 lines and the 

 beak 2 or 3 lines long. 



4. T. Nuttallii, CJi'ivy. About a foot high : leaves glabrous, varying from ol»- 

 long-spatulate and laciuiate-pinnatilid to linear and entire : scapes rather stout ami 

 liead rather large : scales of the involucre narrow : akenes fusiform-linear, slender, 

 llnely and closely ribbed, ecjualling the beak in length. — Proc. Auj. Acad. ix. 21().

 about an inch high. Akenes 4 lines and the beak 3 or 4 lines long. 



5. T, grandiflorum, Gray. Hirsutely pubescent or almost glabrous: leaves 

 lanceolate or oblancciolalc, mostly laciniato-pinnatilid, tho lobes ascending or spread- 

 ing : scape oim to 2.\ feet high : head largo {an inch higli) ; outer scales of tho in- 

 volucre commonly loose and foliaceous, varying from ovate to lanceolate : akenes 

 short-fusiform or oblong, abruptly tapering into the capillary beak of several times 

 its length. — Proc. Am. Acad. ix. 216. Stylopjapjpus grandiflorus, Nutt. 1. c.

 the involucre not dilated : leaves lanceolate or linear and variously laciniate. — 

 Stylopappus laciniatvs, Nutt. 1. c.'i 



Meadows and hillsides, from Monterey Co. along the coast range to Oregon. The var. teiiui- 

 folium has been collected only in Oregon and Washington Territory. The species is well marked 

 when in fruit by the short and small akenes (only 2 lines long), with very long and capillary 

 beak, 6 or 8 lines long. 



* * Root 2>erennial : akenes abruptly beaked from a truncate apex. 



6. T. retrorsum, Gray, 1. c. Almost woolly when young with soft loose hairs, 

 or glabrate : leaves runcinately and deeply pinnatilid, tho linear-lanceolate lobes ull 

 turned downwards, the apex usually prolonged and entire, all tipped with a callous 

 gland : scapes about a foot high : head large (1^ inches long in fruit) but narrow: 

 outer scales of the involucre short and lanceolate, the inner long and linear : akenes 

 short-linear, closely 10-ribbed, their callous or slightly broadened summit very obtuse 

 or truncate at maturity ; the cajullary beak very long. — Macrorhync?i}(s retrorsus,
