to oblanceolate leaves crenate or serrate chiefly above the middle and 
tapering gradually to a broad-winged base; and its subherbaceous 
obtuse or merely acutish bracts are oblong or lanceolate. From other 
American plants of the Virgaurea group, S. Cutleri is quickly dis- 
tinguished by its 30-50-flowered broad heads, its few (2—4, rarely 5) 
large cauline leaves, and its long (3-3.5 mm.) hirsute achenes. It is 
confined apparently to the most alpine districts of New England and 
New York, being known to the writer only from the following moun- 
tains. Marne, Mt. Katahdin; Mt. Bigelow, altitude 1150 m.: New 
HAMPSHIRE, alpine regions of Mts. Adams, Washington, and Monroe; 
summit of Mt. Lafayette: VERMONT, Chin of Mt. Mansfield: New 
York, summit of Mt. Whiteface.— Reported from other high summits, 
but from none of the lesser mountains.

Bot. Cl. v. 320 (1894).— S. Randii includes a large portion of the 
material which has passed with us as S. Virgaurea. In very exposed 
situations it passes to the dwarf extreme which has been separated as 
var. monticola, and which is often mistaken needlessly for S. Cutleri. 
In S. Капай and its variety the heads are 15-30-flowered, in well 
developed plants the cauline leaves are much more numerous than in 
S. Cutleri, and the appressed-setulose or glabrate achenes are only 
2-2.6 mm. long... As far as observed by the writer S. Cutleri and S. 
Капай, var. monticola are of quite different altitudinal distribution. 
As pointed out in the preceding paragraph S. Cutleri is a truly alpine 
species. 8. Randii, var. monticola, on the other hand, is apparently 
unknown on our highest summits, but occurs on the lesser peaks and 
slopes of northern New England. Its most elevated stations are on 
the summits of such mountains as Mt. Willard, New Hampshire 
(793 m.), Mt. Monadnock, New Hampshire (967 m.), and Mt. Wil- 
loughby, Vermont (808 m.); and it descends on the granitic coast of 
eastern Maine to rocks bordering the sea. 
SOLIDAGO HUMILIS Pursh, Fl. 543 (1814). The plant which has 
long passed as S. humilis Pursh or S. Purshii Porter has a most 
unfortunate nomenclatorial history. The plant itself is one of the 
best marked of our eastern species, characterized by its racemose or 
thyrsoid inflorescence, with the often glutinous heads frequently on
