On limestone rocks in Wales. 



On the limestone cliffs of the Great Ormshead, Carnarvonshire, in 

 various places. Mr. If. Wilson, 1825. Communicated also by 

 Dr. Pring, of Bangor, in 1826. 



Shrub. July. 



A small bushy with alternate, spreading or partly recumbent, round, 

 leafy, brown, smooth branches; downy and somewhat angular 

 when young. Thorns none. Leaves alternate, deciduous, ovate, 

 or broadly elliptical, obtuse or acute, entire, an inch long, more 

 or less 3 green, smooth and even above; white, cottony and 

 veiny beneath. Footstalks short, downy. Stipulas in pairs, taper- 

 ing, chesnut-coloured, smooth ; fringed at the edges. Flower- 

 stalks downy, from the same buds as the leaves ; in our speci- 

 mens solitary and single liowered ; in exotic ones often branched, 

 with three or four flowers ; but always shorter than the leaves. 

 Bracteas minute, red, lanceolate, acute. Fl. drooping, pale red. 

 Mr. Wilson describes their structure as follows. 



" Cal. superior, 5-cleft ; segments ovate, blunt, very woolly at the 

 margin, incurved. Pet. 5, orbicular. Filam. 1 6, flat and some- 

 what awl-shaped. German roundish; externally smooth and 

 shining ; woolly within. Stijles 3, sometimes 4, thread-shaped. 

 Fruit pear-shaped, crowned with the closed calyx. Cells, or cap- 

 sules, of the same number as the styles, bony, entire, not valvu- 

 lar, each bearing one style from the lower part of its inner 

 angle." . 



The fruit, at first red, is said finally to turn black. Its pulp is 

 mealy and tasteless. Linneeus recommends this shrub for makmg 

 low hedges, in dry broken ground, as the root runs very deeply 

 into the earth.
