A somewhat recently discovered solidagineous herb of 
Mexico, a plant not far removed in nature from Solidago 
rigida, but with coroniform rather than capillary pappus, on 
account of a mere analogy of its pappus, has been published 
under the wrong genus. This, even though a monotype, 
should form a genus, and may be called 
Stephanodoria tomentella. Xanthocephalum tomentel- 
lum, Robinson, Proc. Am. Acad. xxvii. 172 (1892). Typical 
Xanthocephalum has no pappus at all, but a turgid annulus 
instead; and the genus should be limited to those species, 
apparently. But neither the habit, the inflorescence, the 
involuere nor even the compressed achenes of this plant are 
at agreement with Xanthocephalum or any of its near allies.
