214 
linear to oblong-linear, obtuse. Flowers about 2%" broad. Cap- 
sules 2-214” long by 1-114” broad, oblong, rounded or abruptly ~ 
contracted to the apiculate apex, membranaceous and strongly 
cross-wrinkled, the exposed portion deep purplish in color almost 
from the first, and conspicuously exceeding the sepals. Seeds rela- 
tively large, .03 inch long, linear, 3-5 times longer than broad, pale, 
strongly longitudinally furrowed and minutely cross-lined, under 
the microscope suggesting a miniature ear of corn.* 
As compared with doreale, mutilum, though having sometimes 
the assurgent base of the stem, is commonly erect from the root, 
the stem distinctly quadrangular, the stem-leaves, which reach an 
extreme size of 14’x'7’’, are throughout larger and much broader, 
and vary in shape from ovate-orbicular to ovate-oblong, often 
gradually narrowed from the broadly-dilated base to the obtuse 
tip, sometimes oblong, but always with a broad sub-clasping base; 
5-7-nerved, thin and much reticulated instead of thicker and often 
3-nerved, with the reticulation sparse, obscure or wanting; the 
cymes more compound and delicately dichotomous, with minute - 
and setaceous instead of leafy bracts; the capsule smaller, even 
only half the size(1’-2”” x 14-1’), mostly ovoid- or oblong-conical, 
often but little exceeding the sepals, commonly greenish or, in age, 
greenish-purple, instead of early deep purple; the seeds smaller, 
oblong, only 2-3 times longer than broad, yellowish-brown and 
shining instead of dull whitish, very minutely cross-wrinkled, not 
furrowed, but sometimes indistinctly striate. 
The seeds of doreate, while differing strikingly from those of 
mutilum, resemble somewhat those of Canadense, which, though 
* Besijes the York Harbor series, specimens of Hypericum boreale have been 
examined, as follows: 
Somesville, Mount Desert Island, Maine, Aug. 25, 1890, Edward L. Rand. 
Prince Edward’s Island, Aug. 2, 1888, John Macoun. 
St. John’:, Newfoundland, Aug. 6, 1894, B. L. Robinson and H. Schrenk. 
Notre Dame du Lac, Termiscouta Co., Canada, Aug. 13, 1887, John I. Northrop. 
« Vermont.” 
Lily Lake, Luzerne Co., Pa, Aug. 16, 1889, John K. Small. 
Morris Pond, New Jersey, Sept. 11, 1890, N. L, Britton. 
This last is the apparently intermediate speci.ren already referred to. It is the 
only example seen in which there are any minute bracts in the cymes. 
Hooker’s description of A. guinguenervium of Walter, in Fl. Bor. Am. 1: 
110, clearly refers to HH. doreale, as here defined, and as clearly excludes true 7. 
mutilum, of which guinguenervium is a synonym. The habitat of the plant is given 
as “Canada to Lake Winipeg. Dr. Richardson. Frequent in upper Canada.”
