nomen. 
Frutex; caule primo parce pubescenti maturitate glabro; 
foliis petiolatis palmatinerviis circumscriptione triangulari- 
ovatis 7-10 em. longis 5-8 cm. latis hastatis 3-5-lobatis ciliatis 
mucro-denticulatisque granditer cordatis supra sparse hirtello-

paucicapitatis dense glanduloso-puberulentis, pedunculis gra- 
cilibus remote bracteatis; capitulis 1.2-1.5 em. altis discoideis 
paucicalyculatis; involueri squamis sepius 8 lanceolato-oblongis 
са. 1 em. longis acutis penicillatis extrinsecus hirtello-puberu- 
lentis plus minusve purpuraseentibus interioribus Scarioso-

Specimen examined: 
Mexico: without definite locality, Chrismar (Berlin Herb., 
tracing and fragments in Gray Herb.), туре. 
The affinity of this species is with SS. hederefolius Hemsl., S. 
anisophyllus Klatt, and S. alienus Robinson & Seaton. From 
the first two it differs in having deeply cordate leaves with more 
or less reflexed lateral lobes, and from the last it is readily sep- 
arated by the deeply cordate leaves and absence of peltation.
