ovate, serrated, with transverse nerves ; fertile flowers in glo-

 T±. — The root, boiled with alum, is said to dye yarn of a yellow co- 

 lour ; from the fibres of the stalk a kind of hemp is manufactured, as 

 with the Urtica cannabina of N. America, (Whitlow's Nettle), and 

 I remember having seen several years ago a piece of very good lin^n 

 made from it, under the direction of a lady at Ballitore. In Scotland 

 the young tops of Nettles are boiled and eaten by the peasantry ; and 

 they were also much used by many of the poor in the north of Ireland 

 during the late years of scarcity, owing to the failure of the potato 

 crops.

Hedges, &c. probably introduced. Hedges between Cullenagh and 

 Stradbally, Queen's County, and near Nenagh ; in the largest of the 

 south isles of Arran, creeping over the limestone rocks, and producing 

 excellent hops. Fl. July. %.— Stems long, weak and climbing, sca- 

 brous. Leaves petiolate, opposite, 3 — 5-lobed, serrated, veiny, rough. 

 Flowers greenish yellow. The fragrant bitter, so valuable in the ma- 

 nufacture of beer, resides in the catkins, or cones of the hop, as they 

 are often called.
