tain an irritating fluid, which is consequently applied to the wound they make in penetrating the skin, producing 
inflammation. (Name from wro, to burn.)

The woody branching stem, 6-8 feet high, and long stipitate stings, at once distinguish this Nettle. The woody 
branches are as thick as a crow- or goose-guill, smooth, or, as well as the leaves underneath, pubescent. Petioles 
1-13 inches long. Leaves 3-6 inches, very variable in breadth, entire or lobed at the base. Flowers rather larger 
than in the English U. wrens, similar to them.—Mr. Colenso describes this as stinging violently, the pain lasting for 
four days.

A tall succulent herb, found also in Lord Auckland's Group. Stem smooth, glabrous, or setose, especially at 
the bases of the leaves, 2—4 feet high. Leaves stipulate, 4 inches broad, on petioles 2-4 inches long, opposite or 
ternate, broadly cordate, deeply toothed. Spikes branched or subpaniculate, glabrous or more or less covered with 
stings.

Has. Northern Island. In various places, Colenso, Sinclair, ete. 
A tall slender species, sparingly branched, quite glabrous, or with a few scattered long stings, chiefly on the 
petioles. Stems 2 feet high, weak. Leaves very variable in size, 3-3 inches long, membranous, deeply toothed, 
broadly cordate, acuminate ; petioles 1-3 inches long. Flowers clustered in numerous spikes, which are shorter 
than the petioles. -4chenia enclosed in the two outer larger leaflets of the perianth; sometimes the perianth of the 
fruit is tubular, however, and encloses the achenia.—Also found in Tasmania, where the leaves are often narrow 
and linear. The var. 8 may be a different species, but rather appears a starved weak state; its leaves are very 
narrow, linear-oblong or linear-elongate, 1-3 inches long, and the spikes reduced to little more than axillary 
glomeruli.
