Gray’s A. spinulosus var. canescens, which can only be con- 
sidered a nomen subnudum, was based on Fendler 355, which I 
have not been able to find at the Gray Herbarium. It was referred 
to as “ dwarf, more hoary than in the ordinary plant from which I 
cannot separate it. It is the same as the A. (Blepharodon) Coul- 
teri, Harv. & Gray, ined., from Calif.” Coulter 276 (manuscript 
type of A. Coulteri) is however var. turbinellus, while Palmer 606 
(anno 1876), later labelled A. Coulteri by Gray, is A. gracilis 
(Nutt.) Gray. No sharp line can be drawn between this and the 
three following varieties. 
v A. SPINULOSUs var. turbinellus (Rydb.), comb. nov. Tota planta 
minus pubescens interdum subglabra, plus minusve glandulosa. 
Folia ut apud var. genuinum. Involucrum non pubescens sed dense
