p. 29; Hooker, Fl. Bor. Am. I, p. 303), while that from Herschell Island 
has somewhat broader leaves (lanceolate), thus corresponding to S. alpina, 
y, remotifolia Hoox., 1. c. This form has nothing to do with Saussu- 
rea nuda LEDEB., Fl. alt, IV, p. 16 in nota, which has »involucri 
squamis omnibus subzequilongis«. I think therefore that BriTTon & RYDBERG 
(Bull. New York Bot. Gard., vol. 2, no. 6, 1901, p. 187) are not right in 
recording S. muda from the Yukon territory. Their note on the much 
narrower leaves of their specimens seems to point to S. alpina, var. angusti- 
folia (D.C.) REGEL & TILING.

Dr. H. DantstEDT gives the following additional notes: From the 
other species of the group Ceratophora it differs by the unusually broad 
and short outer involucral leaves. In this character it recalls on 7. hyparc- 
ticum DAHLST. (Arkiv f. Botanik, Stockholm, Bd. 4, 8, 1905, p. 17) and 
its allies, from which it on the other hand differs by the rather well
