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 t, says the P. nana is distinguished from all the 

 allied species by the " foliola 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 striking in our specimens, is hardly 

 referred to in the description of P. nana or of the allied 

 species. 



SANGUisoRBEiE. — Here we have the Alchemilla vulgaris, a 

 well-developed plant. 



ONAGRAREiE. — Amoug the plants before us there are two 

 Epilobiums : one a single imperfect specimen, which may probably 

 pass for the Epilohium angustissimum of Linnseus, among the 

 habitats of which he gives Greenland ; the other the Epilobium 

 latifolium, of which there are several excellent specimens ; the 

 most beautiful indeed in this small collection. 



DeCandoUe says, in his definition of the Epilobium latifoliumj 

 " caule simplici,^^ with a mark of interrogation ; Sir Wm. Hooker 

 says, " caule subramoso." In all our specimens there are several 

 stems arising immediately from the root, while there is hardly 

 any branching in each. 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 byDeCandolle to be " integi-iusculis,'' 

 and by Hooker to be ^^ subintegerrimis.^' On examining the 

 leaves in the specimens before the Society, I find the margins 

 minutely revolute with slight 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 Linnaeus. 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 E. glandulosum of Lehmann. 



Saxifrages. — There are four Saxifrages, the Saxifraga op- 

 positifolia, S. tricuspidata, S. cernua and S. rivularis.
