234. Senecio dileptiifolius Greene in Ottawa Nat., XV (1902). p. 251. 

 Allied to S. aureus, the rather stoutish stems a foot high, from a 



firm short-jointed nearly horizontal rootstock; herbage deep-green and 

 glabrous, small tufts of white wool occupying almost the axils of the 

 leaves and pedicels: lowest leaves with broadly oblanceolate incisely 

 serrate blade an inch long or more, and a slender petiole about as long ; 

 the lower and middle cauline considerably larger and more deeply 

 incised but also petiolate, only the uppermost more nearly lanceolate or 

 linear and sessile, these merely serrate-toothed: cyme of middle sized or 

 smallish narrow heads distinctly subumbellate ; bracts of the cylindric 

 involucre few and broad, oblong-linear and merely acutish: rays about 

 5 or 6, long and light-yellow. 



Canada: Chilliwack Valley. Mr. Macoun's label for this bears the 

 number 26679, and indicated that the plant was collected 29 August at 

 an altitude of 6000 feet, growing with Epilobium spicatum, Eucephalux 

 Engdmannii and Mimulus Lewisii on a mountain slope, from the upper 

 part of which water trickled through the roots of these plants. I name 

 the species in allusion to the general likeness which its leaves bear 

 to those of Lepidkim Virginicum, the type of a genus DUeptium with 

 some authors.
