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



Shrub. July. 



Stems dwarfish, woody, rigid, round, buried in moss, with nume- 

 rous, alternate, leafy branches, t^ach 2 or 3 inches long, depressed, 

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

 obtuse, revolute, shining, on short, broad, fringed, footstalks'. 

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

 aggregate stalhs, each stalk with a convex bracten 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 j nor have 1 ever found them bursting longi- 

 tudinally, as describ-d by an eminent French writer, which is an 

 extremily 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, hell-shaped, regular, spreading, with 5 prominent 

 plaits, and as many very shallow lobes. 'Sect, a gland 

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

 and half its length, awl-shaped, converging. Anth. ter- 

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

 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, imconnected, 

 angular receptacle., whose angles are opposite to each su- 

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

 the base of the receptacle. 



Linufjeus 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 Convolvulus.
