from the shores of Davis’ Straits. 171 
over the whole margin. The description of the P. emarginata 
is rather vague ; it seems indeed, as Sir Wm. Hooker * suggests, 
to be the same as the P. nana. Our species on the whole agrees 
very well with the P. nana, though the name does not seem very 
applicable to it, unless it refer to the large size of the flowers as 
compared with the moderate height of the plant. Lehmann, as 
cited by Hooker+, says the P. nana is distinguished from all the 
allied species by the “ fohola calycina exteriora subrotunda obtu- 
sissima.”” These leaflets in our specimens are certainly roundish, 
though it may be doubted if they come completely up to the 
strong expression just quoted. The remarkable fringing of the 
leaves with silky hairs, so strikimg in our specimens, is hardly 
referred to in the description of P. nana or of the allied 
species. 
SANGUISORBEZ.—Here we have the Alchemilla vulgaris, a 
well-developed plant. 
Onacrarex.—Among the plants before us there are two 
Epilobiums: one a single imperfect specimen, which may probably 
pass for the Epilobium angustissimum of Linnzus, among the 
habitats of which he gives Greenland ; the other the Epilobium 
latifolium, of which there are several excellent specimens ; the 
most beautiful mdeed im this small collection. 
DeCandolle says, in his definition of the Epilobium latifolium, 
“ caule simplici,” with a mark of interrogation ; Sir Wm. Hooker 
says, “caule subramoso.” In all our specimens there are several 
stems arismg immediately from the root, while there is hardly 
any branching ineach. The leaves are ovate-lanceolate, as stated 
by all authorities. It is not however commonly noticed that the 
leaves are distinctly unequal on the opposite sides of the middle 
rib. Again, they are said by DeCandolle to be “ integriusculis,” 
and by Hooker to be “subintegerrimis.” On examining the 
leaves in the specimens before the Society, I find the margins 
minutely revolute with shght irregularities, which give the ap- 
pearance of very small straggling teeth. This appearance has 
possibly given rise to the belief of the leaves not being absolutely 
entire, as the above expressions imply. In these specimens the 
leaves are glabrous, which seems to be less usual. The leaves 
moreover in our specimens are alternate and opposite, as described 
by Linneus. The peduncles are axillary, yet sometimes so close 
as to appear to be ternate or fasciculate. These peduncles, which 
are as long as the flower, are purple and inflated. The calyx is 
coloured as in the EH. glandulosum of Lehmann. 
SaxIFRAGEX.—There are four Saxifrages, the Savxifraga op- 
positifolia, S. tricuspidata, S. cernua and S. rivularis.
