the upper and floral suborbicular with obtuse, obtusish, or scarcely 
acute teeth: calyx-teeth rather broad, flat, subacute, densely pubes- 
cent: corolla very small, white or purple with deeper-colored veins.— 
Alaska, the Aleutian Ids., and Kamtchatka acc. to Wettstein. To 
this species may be referred Mr. J. M. Macoun’s no. 154 from 
Behring Isl. The species seems difficult to separate satisfactorily 
from Æ. latifolia, Pursh. The latter, however, is less hirsute, often 
glandular, more inclined to branch, and has slightly larger flowers. 
++ ++ Calyx-teeth recurved: flowers capitate: corolla white with violet 
veins and yellow eye: White Mountains of New Hampshire, and (?) Mt. 
Katahdin, Maine.

(excellent). Æ. officinalis, var. tatarica, Wats. & Coult. in Gray, Man. 
ed. 6, 392, in part. Very dwarf, 2 to 5 cm. high, the filiform erect 
or often decumbent simple stem bearing 1 to 4 pairs of small ovate- 
orbicular leaves below the dense globular leafy inflorescence (about 
1 cm. in diameter): leaves and bracts finely pubescent upon both 
surfaces, the teeth 5 to 9, very blunt and separated by rounded sinu- 
ses: calyx pubescent, the teeth slightly indurated, curved outward 
in varying degrees or even reflexed: corolla so small as to be incon- 
spicuous even in anthesis, nearly or quite white, marked with deep 
bluish violet veins and yellow eye.— Alpine region of the White 
Mountains, Oakes; W. H. Manning, 9 Aug. 1881; along the Crawford 
trail, near the head of Oakes Gulf and Mt. Munroe, 28 Aug. 1877, 
and 18 Sept. 1891, Æ. Faxon, 20 Aug. 1891, 31 July, 1893, G. G. 
Kennedy, also in the same locality, 4 Aug. 1901, E. F. Williams & 
DB. L. Robinson. Growing in. abundance in dry stony soil with 
Potentilla frigida, etc. While it is not possible to say with certainty 
that the locality particularly mentioned, which is on the western side 
of Mt. Washington toward Mt. Monroe is the one in which the origi- 
nal material was obtained by Oakes, it is now the only locality where 
this plant is known to grow in the White Mountains and it is altogether 
likely that it is the type station. Immature and doubtful plants 
apparently of this species were collected on Mt. Katahdin, altitude 
1225 to 1375 m., 14 July, 1900, by M. L. Fernald ( Rnonona, iii. 176). 
+ + Leaves more or less ciliolate and minutely setulose upon the upper 
surface near the margin (under a lens), otherwise essentially glabrous: corolla 
brownish purple with a yellow eye. 
E. Williamsii. Dwarf, 3 to ro cm. high ; stem erect, simple, fili- 
form, purplish, covered with short crisped white hairs and bear- 
ing beneath the terminal dense leafy head 3 to 5 pairs of leaves: 
leaves green with slight bronze tinge above, 5 to 8 mm. long, cilio- 
late, otherwise essentially glabrous, the lowest ovate-oblong, 7-toothed,
