lo. Senecio fulgens sp. nov. 



Simple and glabrous perennial with a very short caudex : 

 stem about 3 cm. high-: basal leaves oblanceolate, thick and some- 

 what fleshy, with the petiole about 5 cm. long, dentate or suben- 

 tire : lower stem leaves spatulate with a winged petiole, coarsely 

 dentate ; upper stem leaves sessile with an auricled base, lobed 

 with triangular or triangular lanceolate lobes, acute : cyme corym- 

 bose and rather dense : heads about 8 mm. high : bracts about 

 I 5, oblong, acute, with a broad membranous margin ; the calyculate 

 ones few, lanceolate : achene striate, glabrous : rays 4—5 mm. long 

 and 2 mm. wide, dark orange. 



Closely related to the preceding, but differing in the short basal 

 leaves and the lobed upper stem leaves and also in the fewer and 

 broader bracts. It grows at an altitude of about 2700 m. [Plate

II. Senecio CROCATus Rydb. Bull. Torn Club, 24 : 299. 1897 

 Sciurio aureus var. croccus A. Gray, Proc. Acad. Nat. Sci. Phila. 



1863 : 68, 1863 ; not 5. croceus DC. 1837. 



When the above name was published I did not know that this 

 variety of Gray's was a complex one. Hall & Harbour's no. Jji", 

 which is the type, consists of two different things ; but as one of 

 them is rayless it can not be taken as the type of the var. crocatits, 

 which was named from its orange rays. That I did not draw a 

 new diagnosis, I admit, was perhaps careless, but this blunder I 

 think was not worth a page and a half of discussion as it was given 

 by Professor Greene in Pittonia, 4 : 114-116. I committed just 

 the same mistake as Professor Greene himself in establishing An- 

 tcmiana media Greene, Pittonia, 3 : 286. W^hat Professor Greene 

 says of Mr. E. Nelson in Pittonia, 4: 85 can be applied to himself. 

 Gray's description of the var. croccus in the Proceedings of the Phil- 

 adelphia Academy is perhaps not adequate, but this description is 

 supplemented in the Synoptical Flora and elsewhere and I think 

 that Senecio aureus var. croceus Gray is amply published according 

 to all rules we have. If so, Senecio croceus Rydberg is not a nomen 

 nudum, whatever Professor Greene may say. Professor Greene in 

 1897 or 1898 accepted my name, for he named Baker, Earle &
