 and beech-forests in Euahine mountains, Colenso. Middle Island : Dusky Bay, Menzies. 



As has been observed (Syn. Hep.) the leaves are not correctly represented in the 'Musci Exotici,' the three or 

 four rather strongly-marked undulations in the recurved part of the leaf having been overlooked. This is the only 

 known New Zealand representative of the rather large group of Jungermannia, including J. barbata, Schreb., and 

 ■/. ventricosa, Dicks. Of Gymnomitrice no representative has yet been brought from New Zealand, although five 

 inhabit Lord Auckland's and the Falkland Islands, and the British G. concinnaium occurs at Cape Horn, differing 

 in no respect from European specimens. /. minuta, Fl. Antarct., is identical with J. ochrophylla, 1. c, and very 

 different from /. minuta, Crantz, which has not been found in the Southern Hemisphere. 



In /. atrocapilla, Hook. til. et Tayl., from Kerguelen's Land, the form of the leaf gradually passes from ovate 

 bidentate in the cauline, to orbicular, without any trace of the cmargination in those of the involucrum ; but perfect 

 involucra have not been seen. In /. Montagnei, Mitten (Sarcoscyphus laxifolius, Mont., G. L. et N. Syn. Hep. p. 618), 

 a perianth is almost completely formed by the union, almost to their apices, of the upper pair of leaves, which are

 von Esenbeck, is thus quoted.
