188 ) Rhodora [OCTOBER 
2027, not Walter, Car. 209. — Described by Muhlenberg from “ North 
America." Collected by W. W. Eggleston at Norwich, Vermont, Sep- 
tember, 1889 ; also in eastern Massachusetts, at Prides Crossing (Miss 
Anna L. Jackson), Lexington (Miss E. L. Shaw), and at Dedham 
C. E. Faxon). These specimens agree very well with a sheet 
of Muhlenberg's species sent to the Gray Herbarium by Nees 
von Esenbeck. The var. exiguus might readily be mistaken for a 
small-headed A. dumosus, but it is quickly distinguished by its hispi- 
dulous-ciliate leaves and bracts. 
A. VIMINEUS, Lam., var. saxatilis. Stem slender, 1.5 to 6 dm. 
high : leaves mostly ascending : the rather stiff very ascending or rarely 
spreading branches short (5 cm. or less), leafy-bracteate, terminated 
by solitary heads often 1.5 cm. across ; or the branches longer with the 
heads solitary at the tips of the remote slender branchlets. — A char- 
acteristic plant of northeastern river-banks and ledgy shores, flowering 
from late July to early September. Mame, ledgy banks of the Penob- 
scot, Mattawamkeag, September, 1898, in fruit, Pushaw Bridge, Old- 
town, September, 1397, Upper Stillwater, July 29, 1895, no. 361 (M. L. 
Fernald), Orono, August, 1881 (Kate Furbish); rocky banks of the 
Kennebec, Madison, August 21, 1894 (M. L. Fernald); ledges by 
the Androscoggin, Gilead, September, 1897 (Kate Furbish); Wood- 
stock, August, 1887 (F. C. Parlin) : Quesec, Pangan Falls, Gatineau 
River, Sept. 6, 1894 ( Fohn Macoun).— The northern representative 
of A. vimineus, var. foltolosus, Gray, for which it has generally passed. 
That variety, however, as understood by Dr. Gray and as shown by 
his specimens, is a taller plant with more spreading and elongated 
branches, the much smaller heads more abundant and on shorter 
branchlets. 
A. PANICULATUS, Lam., var. cinerascens. Stem slender, 7 to 9 dm. 
high, closely covered, especiall above, with short cinereous hirsute 
pubescence: leaves dull green, thick, lanceolate, acuminate, with 
slightly clasping bases, strongly scabrous on the upper surfaces, sca- 
bridulous beneath and sparingly pubescent on the veins ; margins entire 
or with closely appressed teeth : panicle ascending, with many medium- 
sized heads: involucre about 5 mm. high; the linear-attenuate ap- 
pressed 4- or 5- seriate bracts with distinct green midveins, dark subu- 
late tips and scarious sciliate margins: rays linear, pale lavender, 
about 1 cm. long.— Collected in a damp thicket at Veazie, Maine, 
Sept. 15, 1897 (M. L. Fernald). A plant with the inflorescence of 
A. paniculatus, and apparently a form of that species; but in its cine- 
reous pubescence suggesting 4. undulatus. 
A. TARDIFLORUS, L., var. vestitus. Similar to the species: the 
stem densely villous; the leaves somewhat so beneath.— Gravelly 
shores and low thickets, northern and central Maine, and in the Fran- 
conia region of New Hampshire. Marne, Dover, Sept. 1, 1894, Sept. 
19, 1896, Van Buren, Sept. 11, 1896, Masardis, Sept. 8, 1897 (M. L.
