Description
Species Description - When the above name was published I did not know that this variety of Gray's was a complex one. Hall & Harbour's no. 332, 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. crocaius, 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 Antennana media Greene, Pittonia, 3: 286. What Professor Greene says of Mr. E. Nelson in Pittonia, 4: 85 can be applied to himself. Gray's description of the var. croceus in the Proceedings of the Philadelphia Academy is perhaps not adequate, but this description is supplemented in the Synoptical Flora and -elsewhere and I think that Senecio aureits 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 & Tracy, no. 625, S. crocains Rydberg. This mistake is just as unpardonable because that plant shows none of the characters, assigned to 6". mircus var. croceiis Gray, except the color of the rays, and this character Professor Greene, agrees with nie in regarding as of little value. That Professor Greene and other botanists may know what I now mean by S. crocatus I shall give a diagnosis, here following Professors Greene's example in the case of Antcniiaria media. A glabrous perennial with a short erect rootstock: stem 1.5-3 dm high: basal leaves 2-3 cm. long, obovate or spatulate, crenate or subentire with a winged petiole: lower stem leaves similar but with broader, winged petioles which are somewhat auricled at the base, or else oblong without distinction between blade and petiole and then more auricled: upper stem leaves ovate or triangular with very large and large-toothed aiiricles: cyme small and compact with 2—5 mm. heads, which are 8—10 mm. high: bracts about 20, linear: rays 7-8 mm. long and 1.5-2 mm. wide, orange to pale yellow, achenes striate, glabrous.
