and manifestly pedunculate; involucre low-hemispherical, 

 more than Y^ inch broad, not as high ; bracts subequal in 2 

 series, thin, narrow, lanuginous : rays many, rather conspicu- 

 ous, orange. 



Beautiful little plant, and of a marked specific type, col- 

 lected somewhere in Idaho, by Edw. Palmer, in 1893. 



New Plants from Arizona. 



Senecio quercetorum. a stout hollow-stemmed sparingly 

 leafy perennial a yard high, glabrous throughout, the angular 

 stem notably glaucescent : basal leaves 8-10 inches long, 

 lyrate, the terminal segment ovate, 3 inches long, the laterals 

 small and variable, alternately larger and smaller, all closely 

 and sharply dentate, but with deep and obtuse sinuses between 

 the teeth ; cauline leaves lyrate-pinnatifid, sessile by broad 

 and clasping stipuliform bases : inflorescence an ample broad 

 and much flattened compound cymose corymb of smallish 

 heads : involucres subcampanulate, of 12-15 narrowly lanceo- 

 late acuminate glabrous bracts, with narrow scarious margins : 

 rays about as many, narrow, elongated : pappus fragile. 



Species known only as collected on ' ' Oak Creek ' ' in Ari- 

 zona as long ago as 1883, by H. H. Rusby, distributed by him 

 under n. 672, and with the name 5". Neo-Mexicanus , to which 

 the plant bears no manner of resemblance. As to size and 

 general aspect of stem and foliage it recalls no other Senecio 

 except S. Breweri, which is of the far distant middle Califor- 

 nian seaboard ; and even between these two the differences are 

 marked enough. 



Senecio Blumeri. Many stems and tuft of basal leaves 

 crowning an ascending tap root, the whole plant 10 inches 

 high: leaves 1/4-3 inches long, of firm almost subcoriaceous 

 texture ; blades obovoid, very obtuse, lightly and coarsely 

 crenate, tapering to a petiole of their own length, glabrate and 

 pallid above, beneath white-tomentose : stems nearly naked,
