hoariness, and even shrivelled up under the influence of the 
summer heats; and I had mot much sooner come to a full 
realization of having confused two species than my friend 
Mr. Pollard informed me that he had reached the same con- 
clusion. A decipiens is manifestly a northern species, reach- 
ing its southern limit in Maryland and Virginia, and being 
much more common in Pennsylvania and New York, rang- 
ing westward to the prairie region toward the Mississippi or 
even beyond it,and northward to Mt. Desert Island, whence 
Mr. Bicknell has it. It is also in the Canadian Survey col- 
lection, under the following numbers: 11295, in dry woods, 
Vicinity of Belleville, Ontario, 20 May, 1878, Macoun; 11298, 
sandy woods, Nipigon, Lake Superior, 24 June, 1884; also 
forming part of a much confused sheet n. 11296, the one 
specimen of true A. decipiens being ticketed, * Woods and 
meadows near Belleville, 28 May, 1865." In northern and 
western specimens it appears in both male and female forms. 
Near Washington the female plant of A. decipiens is as much 
unknown asis the maleof A. plantaginifolia, hence my former 
strong inclination to make of the two the mere sexes of one 
Speeies. 
A. FOLIACEA. More than a foot high, slender, the short 
stolons densely leafy, their leaves cuneate-obovate to obovate- 
spatulate, 4 to 2 inch long, very broad in proportion to their 
length, acutish, of thin texture, lightly and permanently 
silky-tomentose on both faces; cauline leaves much larger, 
l inch long or more, oblong or spatulate oblong, sessile and 
clasping, very obtuse or even almost truncate at the broad 
apex; heads rather slenderly pedicellate in a compound 
cyme; involucres not large, their bracts in only about two 
series, the white tips of the outer series oval, obtusish, of the 
inner lanceolate, acute. oo 
Little Belt Mountains, Montana, 18 Aug., 1896, J. H. Flod- 
man, n. 867. Remarkable for the very ample cauline leaves, 
these less hoary and several times larger than those of the 
stolons.
