41. _Campanula_ with a contracted flower. (_C. uniflora._) Differs from the common blue kind, (_rotundifolia,_) in having the leaves as well as the flower much contracted at the base, so that the latter is funnel-shaped. The embryo is oblong, with six sides, rough, with three orifices near the base of the calyx. 42. _Lychnis_ with a concealed flower. (_L. apetala._) Leaves pink-like. Flower solitary at the top of the stalk. Calyx ovate, inflated, closed, with ten black hispid ribs, which branch near the top. Petals five, oblong, brownish, shaped exactly like the usual claws of a _Lychnis_, but without any border. Stamens ten. Embryo oblong, inclining to cylindrical, contracted in the middle, obtuse, blackish. Pistils five, whitish. The petals, stamens and pistils are all concealed within the calyx. 43. A small _Aster_, with one solitary white flower. (_Erigeron uniflorum._) It has the calyx of the _Amellus_, the flower of a daisy, white with a yellow disk. 44. A viviparous grass, _Poa_. (Rather _Festuca vivipara_.) 45. _Juncus_ with a sharp rigid point. (_Juncus_, _n. 116. Fl. Lapp._) 46. A Catchfly which is not viscid, with the flowers collected into a tuft. (_Lychnis alpina._) 47. A smooth _Cerastium_, agreeing in every respect with the large-flowered one, except the hairiness and hoary aspect of the leaves. (_C. alpinum_, a smooth variety.) I observed every where about the sides of the hills holes dug by the Lemming Rat. (_Mus Lemmus._) Hares are grey in summer upon the alps. No herb or tree on the highest parts of these alps attains more than a quarter of an ell in height, though in the valleys the same species may perhaps be two or three feet high. Birch trees, which however are very scarce, creep in a manner under the earth, throwing up the tips of their branches here and there to the height of a quarter of an ell. Tender shoots of this kind sometimes conceal a very knotty depressed stem.
