Hab. Throughout Canada to lat. 64°. Columbia. Dr. Scouler. Douglas.—This plant seems universally
diffused through all the woody country of North America. I possess it from California and from
Louisiana. Dr. Gillies found it at Mendoza, in extra-tropical South America. I have referred the S. tenuifolia
of Richardson to a state of this plant, rather than considered it the S. tenuifolia of Pursh, which is a
southern plant, its extreme northern limit being, I believe, New Jersey.

■ * The whole of my Collection of this extensive Genus has been named by the'kindness of Dr. Boott and Professor
Lindley; the former of whom may be considered excellent authority for the Linnaean and Banksian species.: the latter
for those of Nees von Esenbeck, whose arrangement I have implicitly followed. Professor Lindley has likewise determined
and characterized the new species. For more full characters of the Genus Aster and its divisions, as well as
other genera of the Asterea, than I can here give, I must refer to the valuable “ Genera et Species Asterearum" of Dr.
Nees von Esenbeck.
Hab. Arctic sea-coast. Dr. Richardson.—“ A. salsuginoso affinis,” (Lindl.) and perhaps only a dwarf,
or hairy variety of it.

consider this as scarcely distinct from A. Caucasicus, Willd. and that it may even be the same with A.pere-
grinus.—Specimens of our var. /3. in Mr. Drummond’s Collection, which Professor Lindley marks “ apparently
A. Unalaschkensis, Linn.” a species which I have not seen, are larger than A. Caucasicus; a foot
and a half to two feet high, with very thin, membranaceous, indistinctly veined, and scarcely and only very
distantly serrated leaves: the flowers similar, but more numerous.
