162 * BOTANT. 



ascending or erect from a fusiform caudex ; radical leaves 2-3' long, lanceo- 

 late or linear, acuminate, narrowed into a petiole, laciuiately pinnatifid ; 

 cauline ones smaller, toothed, the uppermost entire and bractlike ; heads 

 solitary or with 1-2 lower ones on short peduncles, 8-12" broad ; involucres 

 hemispherical, of many oblong, rather obtuse, herbaceous-tipped scales, 

 imbricated in several rows ; rays 18-24; style of the disk-flowers with very 

 hispid lanceolate appendages nearly twice longer than the stigmatic portion ; 

 achenia striate, glabrous ; pappus tawny- white, copious, of unequal scabrous 

 bristles, some of the longer ones slightly clavate. — With much of the habit 

 of A. lanceolatus this species has the achenia and pappus of the section 

 Pyrrocoma, to which Dr. Gray has referred it. California, (Bolander;) 

 Carson City, Nevada, (Anderson.) 



Aplopappus paniculatus, Grray, /. c. {Pyrrocoma paniculata, T. & Gr.) 

 Grlabrous ; stems several, 1° high, nearly erect from a fusiform caudex ; 

 radical leaves petioled, oblong-Mnceolate, mucronate, obscurely serrulate, 3-5, 

 long ; the cauline ones lanceolate from a broad clasping base ; heads several, 

 rather large, sessile in the axils of bracteal leaves ; involucres campanulate, 

 of many oblong-ovate herbaceous-tipped scales, closely imbricated in several 

 rows; rays 10-12, slender; style of the disk-flowers with subulate hispid 

 appendages, twice longer but narrower than the stigmatic portion ; achenia 

 flattened, nearly glabrous ; pappus tawny-white, of nearly equal scabrous 

 fragile capillary bristles.— Oregon, (Nuttall.) • Var. viegatus. Gray, I. c. 

 Heads more numerous and smaller ; leaves narrowly lanceolate, glaucous, 

 entire.— California, (Bolander ;) Carson City, Nevada, (Anderson.) 



A plant much like this species, but of lower stature and with the heads 

 somewhat corymbose on slender peduncles and with very tawny pappus, was 

 collected near Virginia City by Bloomer. 



Aplopappus Paeeyi, Gray. Sill Jour., {n. s.,) 33. 10. Stems erect, 

 6-18' high, viscidly puberulent towardg the summit, leafy, corymbosely 

 branched above ; leaves nearly glabrous ; the lower ones oblong-obovate, 

 obtuse, entire, narrowed into a petiole ; the upper ones sessile, oblong-ovate 

 or oblanceolate ; heads few or many, nearly sessile in corymbed clusters ; 

 involucres 4-6" broad, campanulate ; the oblong obtuse scales imbricated in 

 several rows, chartaceous, the outer ones more foliaceous ; rays 12-20, small 

 and narrow, pale-yellow ; disk-flowers numerous ; appendages of the style 

 lanceolate, slightly hispid, rather longer than the stigmatic portion ; achenia
