subadhærentem obscure coalitis, extus pilosis. Perianthium ½—¾ unc. longum, extus pilis fulvis tomentosum, tubo gracili superne ampliato, laciniis ovato-oblongis, fauce inter stamina barbata, pilis brevibus flaccidis articulatis ereberrimeque transversim striatis. Stamina filamentis breviusculis, antherarum apicibus exsertis. Stigmata 3 parva, inter tubum corollæ retracta.
A very distinct species from the former, in the foliage especially. Hitherto it has been found in the Straits of Magalhaens only.

A curious little plant, confined in its geographical range to the mountains of Antarctic America, and represented in New Zealand by a very similar one, forming its only congener, the D. Dieffenbachii, Hook. (Lond. Journ. of Bot. vol. ii. p. 497. t. 17). However similar the two plants are in habit and in their more important structural characters, differences exist which some botanists may deem of generic value; these are, the cylindrical continuous base of the perigonium, thickened faux and capitate glandular stigma of the New Zealand species, contrasted with the jointed angulated tube of the perigonium in the Antarctic American plant, which has an eglandulose faux and plumose stigma. The thickening of the throat of the perianth in D. Dieffenbachii, which almost causes the faux to be closed with scales, is effected by the three nerves of each segment being there joined by anastomosing venules, whilst in D. muscosa they run free to the apex of the segment.

1. URTICA, L.
1. Urtica Darwinii, Hook, fil.; caule gracili erecto sparsissime piloso v. glabemmo, foliis inembranaceis oppositis petiolatis ovatis acuminatis grosse æqualiter crenato-serratis basi rotundatis 3-nerviis utrinque subtilissime punctatis tenuiter puberalis, petiolo gracili, stipulis lineari-oblongis subacutis, floribus glomeratis glomerulis setosis in spicas graciles interruptas petiolo longiores dispositis.
Hab. Chonos Archipelago, C. Darwin, Esq.
Caulis penna corvina tenuior, flaccida, glaberrima, v. pilis raris albidis valde inconspicuis sparsa, internodiis 1½ uncialibus. Stipulæ 3 lin. longæ, sidiacutæ. Petioli ½—¾ unc. longi, graciles parec puberuli. Folia 2-3 unc. longa, 1¼—1½ lata, grosse crenato-serrata, segmentis sinubusque latis acutis. Pedicelli axillares, subquaterni, patuli, penduli, petiolo ½ v. bis longiores. Flores in glomerulos sparsos congesti; glomerulis setosis, paucis inferioribus masculis ceteris fœmineis.
In appearance this very closely resembles the Pilea pumila of North America, though it is more nearly related to the Urtica gracilis of the United States. Both this latter plant and the U. Darwinii differ from U. dioica, L., in the much larger flowers and achænia.
