64 PROCEEDINGS OP THE AMERICAN ACADEMY 



C. RUNCINATA, HBK. 1. c. ; DC. 1. c. 327. Senecio cirsioides, 

 Hemsl. 1. c. 238. I have only Licbmann's specimen, no. 393. It is 

 nearly related to the preceding, but is low, woolly, and bears fewer 

 und larger heads. 



§ 4. West Indian, of peculiar habit, shrubby : corolla-lobes much 



longer than the throat. 



C. DISCOLOR, Grisebach, Cat. PI. Cub. 



Senecio. The study of the North American species for the Sy- 

 noptical Flora brings in a few changes in nomenclature, mostly relat- 

 ing to forms which have been named for collectors without revision of 

 the whole ground ; also a few new forms. Mere notes or indications 

 may suffice for the present. 



Senecio Rugelia. Rubella nudicaulis, Shuttlew. in coll. Rugel, 

 taken up by Chapman, is a good Senecio, not so near Arnica as might 

 at first be thought. 



Senecio AVhippleanus-is the S. eurycephalus, var. major, Gray in 

 Pacif. Yj. p]xped. iv. Ill, a species to rank next to S. Mendocinensis. 



Senecio Hautwegi, Benth., belongs to a peculiar Mexican group, 

 and was collected in a glabrous form, within our limits in S. Arizona, 

 in 1882, by Lemmon. 



Senecio Huachccanus, sparingly collected by Lemmon, at the 

 same time, is a new species related to S. triangularis and S. Andinus. 

 It has smaller heads than the latter, and broader leaves, the upper ones 

 all partly clasping by a broad base, instead of attenuate. 



Senecio crassulus is a name which I am obliged to give to a 

 species of the Colorado Rocky INIountains (extending, however, to the 

 northern part of Wyoming), the S. integerrimus, Gray in Am. Jour. 

 Sci. xxxiii. 11, «fe Proc. Acad. Philad. 1863, 67, not of Nuttall, first 

 collected by Parry. It is remarkable for its thickened involucre, be- 

 coming conical after an thesis, and multangular by the fieshy carination 

 of its bracts ; the character striking in the living plant. 



Senecio Clevelandi, Greene, is a well-marked Californian spe- 

 cies, the characters of which are published in Bull. Torr. Club, while 

 this paper is passing tlirough the press. 



Senecio werneri^ekolius is S. aureus? vaT.tvernericefolius, Gray, 

 Proc. Acad. Philad. ISG-i G8. 



Senecio petr.iu'S, Klatt, in Abh. Nat. Gesell. Ilalle, xv.. is ^S". 

 aureus? var. nlpintis. Gray, Am. Jour. Sci. 1. c, which must also be 

 allowed to be a distinct species. 



Senecio Cardamine, Greene, Bull. Torr. Club, of the mountains
