Very dwarf, stems much branched, mainly under soil, moss, or 

 stones, branches short 3-5-leaved, glabrous (or rarely pubescent 

 at first) ; buds ovoid, glabrous or very soon glabrescent. Stipules 

 0, or rare, minute ovate. Leaf-blades \-l in. long, commonly 

 round, sometimes broadly ovate or roundly obovate, round or 

 retuse at the tip, base usually cordate, or rounded; serrate or 

 crenate-serrate from the base with incurving teeth, sometimes 

 crenate, glabrous, green on both sides, shining, often more glossy 

 below than above. Catkins J-f in. long, following the leaves in 

 June or July, on short leafless pubescent peduncles, terminal, leaf- 

 opposed with a bud between, round or shortly oblong ; $ small, 

 \ in. long, few-flowered, filaments glabrous, anthers sometimes 

 tipped with red ; ? \-\ in. long, elongate to nearly an inch rarely, 

 3-12-flowered ; bracts oblong or narrowly obovate obtuse, invol- 

 vent, with reddish margin above, glabrous or thinly pubescent ; 

 ovaries ovate-conic obtuse, glabrous, often turning reddish or 

 purplish-red, subsessile or shortly pedicelled in fruit ; nectaries 

 single or double, external linear or sometimes obsolete, internal 

 linear or sometimes cleft, usually exceeding any pedicel ; style 

 variable, not very long, often divided below the stigmas nearly 

 to the base. 



There is a wide difference of aspect between the very small- 

 leaved form of exposed ridges and mountain-tops and a large- 

 leaved form or state on wet rocks ; the latter sometimes has 

 the stem partially exposed through denudation of the soil. There 

 is a slight variation in the 2 catkin, the ovaries having sometimes 

 (as B. White pointed out, I. c. p. 437) a few hairs or even lines of 

 hairs from the base upwards, and the pedicels being sometimes 

 silkily pubescent also. The latter is a slight and inconstant 

 modification, the former due to situation and character of the
