Side of Enagh Lough, County of Derry ; Mr. D. Moore. 1834. 

 Fl. May. T? . — A low, spreading, smooth bush, whose long, recum- 

 bent, brown or purplish branches take root as they extend in every 

 direction. Leaves on shortish footstalks, not much spreading, about 

 two inches long, not one broad ; very acute at the point; not at all 

 rounded at the base ; smooth at all times, except an obscure downiness 

 on the midrib above ; harsh to the touch, bitter, variously crenated or 

 serrated, the serratures peculiarly, and sometimes remarkably undu- 

 lated ; the upper side of a dark shining green ; under glaucous. I 

 have not as yet seen the catkins of Irish specimens.

Summits of Tomlagee and Lugnaquilla, the two highest of the Wick- 

 low mountains, and Slieve Donanl, County of Down. An unusually 

 large variety was found by Mr. Teinpleton on the top of Slieve-Nance, 

 County of Antrim, similar to some of the large varieties gathored by 

 Mr. M'Nab, of Edinburgh, on the mountains of Sutherland. Fl. June.
