GREENMAN—NORTH AMERICAN SENECIONEJE 275 
Mexico: Sandy plains near Altar, State of Sonora, 4 April, 
1884, C. G. Pringle (Gray Herb.). 
This species has been hitherto included with S. Douglasii 
DC. from which it differs in being essentially glabrous through- 
out, in having usually more numerous and shorter lateral 
leaf-segments, fewer, shorter, and less conspicuous calyculate 
bracteoles.

Specimen examined: 
Mexico: State of Oaxaca, mountains of Telixtlahuaca, altitude 
2500 m., 10 December, 1894, Rev. Lucius C. Smith, 367 
(Gray Herb., photograph and fragments in Mo. Bot. Gard. 
Herb.), TYPE. 
Although only the upper part of the plant is at present known 
to the writer, nevertheless it evidently belongs to the section 
Suffruticosi and appears to be most closely related to S. Picridis 
Schauer and S. alvarezensis Greenm. From the former it differs 
by the usually broader base of the upper stem leaves, more 
numerous heads and conspicuous bracteoles, while from the 
latter it is readily separated on foliar characters alone.
