Hab. Canada. (Nees.) Lake Huron. Dr. Todd.—This is Nees’ A. vimineus: but Dr. Boott considers
it as probably a variety of A. puniceus.
23. A. laxifolius ; foliis anguste lanceolatis utrinque attenuatis mucronato-serrulatis
flaccidis supra scabris, caule scabro racemoso-composito angusto, ramis apice racemosis vel

Dr. Richardson.—This is a very distinct and well marked species. The more northern specimens have the
narrowest leaves. I possess the same plant from Philadelphia, sent to me by Dr. Griffith.

H ab. /3. Canada. Mrs. Percival.—This, which Professor Lindley, and, I doubt not, correctly, refers to
A. luxurians (5. of Nees, Dr. Boott considers A. tardiflorus, Nees, (not Linn.) while another, equally quoted
by Dr. Lindley under A. luxurians, /3. Dr. Boott calls A. Novi Belgii, 3. minor. The three are perhaps not
really different.—Nearly allied to this is a specimen of an Aster from Dr. Scouler, gathered on the Columbia,
which Professor Lindley inclines to refer to A. asper.

This certainly bears considerable resemblance to A. laxifolius, Nees, to which indeed Dr. Boott refers it.

• Hab. Canada. (Lamarck.) Saskatchawan. Dr. Richardson. Drummond.—To me this appears very
similar to the preceding. Nees considers it unlike any species but A. divergens.
