Drummond. Dr. Richardson. Newfoundland. Miss Brenton. Labrador. Dr. Morrison.—This is most
allied to P. rotundifolia; but the leaves are smaller than their smallest state in that species, and singularly
opaque. The flowers are nearly the same in size, but the calyx is .much smaller and more appressed;
the anthers have two tubular horns, at the top of which the pores are situated. The style is shorter and
less flexuose. It agrees in every respect'with an original specimen from Swartz, and in America seems to
be peculiarly abundant in the latitude of the Saskatchewan, from Hudson’s Bay to the Mountains. The
P. chlorantha of Hook, in Parry’s 3d Voy. App., should be referred to P. rotundifolia 3. pumila.

Arctic Islands. Capt. Sir E. Parry.—Very numerous specimens of this plant in my Herbarium have satisfied
me that, in regard to foliage, this is a very variable species, and that none of them can with propriety be
separated from P. rotundifolia; whilst some have their leaves less than an inch in length, others are more than
2£ inches long, and full 3 inches broad. The flowers are the same shape in all, and essentially distinguished
from P. chlorantha by the much larger and more membranaceous calyx, by the anthers destitute of tubular
pores, and the longer and more flexuose style. Sometimes the flowers are white, at other times deep rose-
colour, with the anthers quite red. There cannot be a question, I think, but the broader and reniform-leaved
variety is the true P. asarifolia of Michaux, though some of the American Botanists have taken the P. chlorantha
for it, which could hardly have suggested Michaux’s name.

Hab. Sledge Island, on the N. W. Coast, Nelson.— With this I am unacquainted, unless, as I cannot help
suspecting, it may be my var. pumila of P. rotundifolia, with which it sufficiently accords, and which is
found in Unalaschka. Mr. Don says it resembles P. minor in general habit, but is much smaller, and possesses
characters widely different.
7. P. bracteata; foliis lato-ovatis acutis integerrimis seu Isevissime crenatis coriaceis acutis

calycis segmentis attenuatis alabastro longioribus.

Drummond.—Well distinguished by Mr. Nuttall from P. rotundifolia, being very different in the foliage. The
flowers are intermediate between those of rotundifolia and chlorantha, having the calyx of the latter, and the
longer style of the former; the cells are a little produced below the pores. Blossoms exceedingly fragrant,
white.
