On alpine moors. 



On the heathy summits of most of the mountains of Scotland. 



Shrub. July. 



Stems dwarfishj woodyj rigid, round, buried in moss, with nume- 

 rouSj alternate, leafy branches, each 2 or 3 inches long, depressed, 

 spreading in all directions. Leaves opposite, small, elliptical, 

 obtusCj revolute, shining, on short, broad, fringed, footstalks. 

 Flowers small^ rose-coloured, on simple, smooth, red, terminal, 

 aggregate stalks, each stalk with a convex bractea at its base. 

 Coat of the capsule spongy, with a deciduous cuticle. The an- 

 thers consist of 2 cells, each cell opening by a rather wide pore, 

 with a blunt border ; nor have 1 ever found them bursting longi- 

 tudinally, as described by an eminent French writer, which is an 

 extremely rare character in this natural order., if not absolutely 

 inconsistent therewith. See Hooker 230.

Cal. inferior, of 1 leaf, small, in 5 rather deep, ovate, imbri- 

 cated, converging, permanent segments. Cor. of 1 petal, 

 large, bell-shaped, regular, spreading, with 5 prominent 

 plaits, and as many very shallow lobes. Ncct. a gland 

 under the germen. Filam. from the base of the corolla, 

 and half its length, awl-shaped, converging. A^ith. ter- 

 minal, erect, arrow-shaped. Germ, roundish. Style 

 thread-shaped, as long as the stamens. Stigmas 2, spread- 

 ing, oblong. Caps, invested with the calyx, roundish, 

 either valvular, or bursting irregularly, of 1, 2, or 3, 

 more or less complete, cells, with a central, unconnected, 

 angular receptacle, whose angles ai-e opposite to each su- 

 ture. Seeds large, roundish, 2 in each cell, attached to 

 the base of the receptacle. 



Linnseus observes there are few genera in which one part or 

 other of the fructification does not evade a strict limitation 

 of character. Such is the case with the seed-vessel in the 

 very natural genus Cunvolvulus.
