90 i PITTONIA, 
SENECIO ScORZONELLA. Perennial from stout horizontal 
or ascending and apparently branched rootstocks: herbage 
rather sparsely floceulent, or somewhat arachnoid through- - 
out, perhaps glabrate in age: leaves in a radical tuft, sub- 
erect, 5 or 6 inches long, broadly oblanceolate, somewhat 
spatulately tapering to a narrow scarcely petiolate base, the 
margin coarsely, irregularly and retrorsely lacerate-toothed 
in the broad upper portion, the tapering lower part entire: 
scapiform stem 12 to 18 inches high, bearing 2 or 3 small 
entire leafy bracts: heads 20 or more, in a somewhat panicu- 
late terminal corymb, of the size of those of A. aronicoides 
and radiate; involucral bracts 10 to 14, obtusish, the invo- 
lucre subtended by two or three separate and somewhat 
remote more foliaceous ones: ovaries glabrous, the mature 
fruit not known. 
Plant of northeastern California, sparingly collected by 
Mrs. Austin, whose earlier immature and less satisfactory 
specimens were provisionally referred by Gray to S. aroni- 
coides. 
ERECHTITES POLYPODIOIDES. Senecio gracilipes, R. & G» 
Am, Journ. Sci. 3 ser. 1. 156.—This beautiful plant of Mr. 
Pringle’s Mexican collection of 1894 is hardly a Senecio; 
though were it of that genus it would need to be called 
Senecio polypodioides, on account of the established 8. gra- 
cilipes of Peru, so named long ago by Asa Gray.
