subadhferenteui obscure coalilis, extus pilosis. Perianthium i— | unc. longum, extus pilis fulvis tomentosum, tubo 

 gracili superne ampliato, laciniis ovato-oblongis, fauce inter stamina barbata, pibs brevibus flaccidis artieulati? 

 ereberrimeque transversim striatis. Stamina filamentis breviusculis, antherarum apicibus exsertis. Stigmata 3 parva, 

 inter tubuni corollas retracta. 



A very distinct species from the former, in tbe foliage especially. Hitherto it has been found in the Straits of 

 Magalhaens oidy.

A cm-ions little plant, confined in its geographical range to the mountains of Antarctic America, and repre- 

 sented in New Zealand by a very similar one, forming its only congener, the D. Bieffenbachii , 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 I). Dieffeniachii, 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.

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 achsenia.
