Dr. O. Swartz. In sinu Dusky bay dicto. D. Menzies, 1791. 
Caulis repens, flexuosus, rigidus, foliis destitutus. Rami rigidi 
palmares, erecti, iterum divisi, innovationibus precipue. Fo- 
lia lutescente-viridia, arcte imbricata, horizontalia, disticha, 
verticalia, dimidiato-ovata, superne convexa, margine inferne 
recurvo, ubique denticulato-ciliata, basi decurrentia, superiora 
majora. Substantia reticulata, areolis minutis, rotundatis. 
Perichetialia magis ovata, calyci appressa, Calyx termina- 
lis, urceolatus, basi ventricosus, superne compressus, ore fim- 
briato. Seta calyce vix duplo longior. Capsula ovata, nigro- 
fusca, quadrivalvis, 
This species is very nearly allied to J. spinulosa, differing from 
it in the form of the leaves and denticulation, and like that, pro- 
bably subject to great variations, It well accords with Swartz’s 
description ; but among the specimens under that name which I 
have received from that liberal naturalist are two kinds, which, if 
they do not differ specifically from the one here described, merit 
at least a separate figure as very remarkable varieties. Indced in 
Mr. Menzies’s collection are two other Jungermannia which I 
can only find to differ from the present, the one in its smaller size, 
the other in its almost simple mode of growth, more distantly 
placed and broader leaves. They are all found in Dusky bay, 
New Zealand.
