26 PLANTS BAKERIAN^E. 



SENECIO PENTODONTUS. Dwarf, multicipitous, the scapi- 

 form peduncles 3 to 5 inches high, the tufted and upright 

 leaves scarcely half as high, these subcoriaceous, their obo 

 vate-spatulate obtuse mostly 5-toothed (often 3-toothed, or 

 even quite entire) blades commonly about as long as the 

 petioles; growing parts of the plant hoary- tomentulose, the 

 older foliage glabrate : peduncles with one or more narrow 

 bracts and bearing mostly 3 slender-pedicel led heads; in- 

 volucres subcylindric, nearly J inch high, their bracts thin, 

 narrowly lanceolate: rays few, yellow, oblong, shorter than 

 the involucral bracts. 



On open knolls below the limit of trees, near Carson, 2 

 July, n. 309. An interesting subalpine Senecio which may 

 be regarded as in a manner intermediate between two such 

 different species as S. petrocallis and .8. wernerisefolius. 



The other Senecios of the sets are the following : 8. admir- 

 abilis, Greene, 732, 875, both fine specimens; '8. amplectens, 

 Gray, 719, 771, also beautifully illustrating this species; 

 S. atratus, Greene,? 756, the foliage too thin and too faintly 

 dentate, perhaps almost as near S. milleflorus ; S. blitoides, 

 Greene, 341,755 ; S.carthamoides, Greene, 731, 851, both num- 

 bers excellent ; 8. chloranthus, Greene, 523, not exactly typi- 

 cal ; S. crassulUSj Gray, 774 ; S. eremophilus, Rich, 596, 748 ; 

 S. Fendleri, Gray, 516, an unusual state with no pinnatifid 

 leaves, 857, quite nearly typical; S.flavulus, Greene, 114, 176; 

 8. Holm.ii, Greene, 729; S. integerrimus, Nutt., 44; S. ladu- 

 cinus, Greene, 772 ; 8. milleflorus, Greene, 525 ; S. mutabilis, 

 Greene, 19, 33. 180. S. petrocallis, Greene, 770; S. pudicus, 

 Greene, 683, 858; S. spartiodes, Torr. & Gray, 446. 



ARNICA LANULOSA. Gregarious by horizontal root-stocks, 

 the many stems rather low, 5 to 10 inches high, stoutish,
