Senecio Earlei. ^ $' £*™M" 0\+*'fr< 



Perennial, bright green, densely cottony below, sparingly so 

 and glabrate above. Stems usually tufted, erect or ascending, 2-5 

 cm. tall, simple or nearly so below, corymbosely branched above : 

 leaves various, basal quite numerous ; blades oval or oblong, 1.5—6 

 cm. long, serrate, obtuse or retuse, often crimson beneath : petioles 

 longer than the blades ; stem-leaves pinnatifid, linear-lanceolate or 

 oblong, the lower ones with petioles, the upper sessile : pedicels 

 slender : involucres hemispheric, 8—9 mm. broad, 8-10 mm. high : 

 bracts of the involucres linear or nearly so, 5-5.5 mm. long, acute, 

 hyaline-margined : rays oblong, 4-6 mm. long, bright yellow, 

 corolla yellow, 4-4.5 mm. long; segments triangular or ovate: 

 style glabrous : achenes 3 mm. long, scabro-pubescent on the angles. 



In dry soil, Tennessee and Alabama. Spring and summer. 



A showy species related to Soicao tomentosus. The main 

 points of difference are : First, the almost wholly glabrous foliage, 

 only the base of the plant permanently woolly. Second, the 

 shorter petioles, and shorter, more rounded and more finely toothed 

 leaf-blades. Third, the more open inflorescence and more numer- 

 ous heads. Named for Prof. F. S. Earle, of Auburn, Alabama. 



I have the following specimens : 



Alabama: Auburn, Lee County, 1896, Earle and Underwood. 



Tennessee: Knoxville, Knox County, 1897, Ruth, number 



421 1.
