few, resembling the others, but with shorter petioles. Bracts 3-eleft 

 or entire, opposite or solitary. Flowers solitary, or in a cyme of 

 2 or 3, on very long pedicels. Calyx - segments ovate, as long 

 as the' tube; calyx-tube hemispherical, adhering to the ovary. 

 Petals oblong, exceeding the sepals. Capsule nearly two-thirds 

 superior, exceeding the calyx-segments, with 2 very short beaks- 

 Plant sparingly glandular-pubescent. 



On damp ledges of Alpine rocks. Pare. Most abundant on the 

 mountains of Braemar, but also on Ben-Nevis, Ben-Lawers, and 

 also stated to occur in Eorfarshire and Moray. 



Scotland. Perennial. Summer. 



Stems 1 to 3 inches long, growing in small tufts. Petioles of 

 the radical leaves about as long as the stems ; lamina | to £ inch 

 across. Blowers white, J inch in diameter. Petals varying from 

 a quarter to twice as long as the sepals. Capsule \ to f men 

 lone, suddenly acuminated into 2 short diverging beaks, the 

 superior part with a few prominent transverse veins. Plant dull 

 lurid green, sparingly clothed with long, shaggy, jointed, glandular 



The barren shoots of this plant have the bases of the short 

 leaf-stalks (which are destitute of lamina?) thickened so as to form 

 small bulbs; later in the year some of these shoots may be 

 found elongated, with the scale-like bases of the leaf-stalks more 

 remote, and often bearing the rudiment of a lamina ; m which case 

 they have some resemblance to the young subterranean stolons ol 

 Epilobium alsinifolium.

 Perennial. Barren shoots represented by oblong-ovoid scaly 

 bulbs at the crown of the rootstock. Stem erect, simple, curved 

 at the apex before flowering, at length straight. Lowest leaves 

 stalked, roimdish-reniform in outline, palmately 5-lobed, cordate at 

 the base; lobes roundish or ovate, subacute; petioles slender, about 

 twice as long as the lamina; stem-leaves numerous, shortly 

 stalked, the lower ones resembling the root-leaves, but witli 

 longer and more acute lobes; upper stem-leaves rhomboidal and 

 lobed, the uppermost entire, most of them, especially the upper- 

 most, with scaly bulbs in the axils. Bracts entire, strapshaped, 

 solitarv. Blowers solitary, or in a cyme of 2 or 3, on rather short
