Has. Lord Auckland's group; on wet rocks near the sea, in the beds of streams, &c., forming large 
patches. 
Cespites majusculi, 3-4 une. lati, fusco-purpurei, innovationibus pallide olivaceis. Caules nigricantes, sub 2 
unc. longi, flaceidi, vage ramosi, procumbentes v. prostrati. Folia magnitudine varia, plerumque majuscula, 14 lin. 
longa, laxe cellulosa, tenerrima, pellucida, apicibus rotundatis seepe recurvis, marginibus interdum undulatis. Stipule 
bifidee, segmentis subulatis erectis approximatis. 
This exhibits much the habit and mode of growth of the last, but is a widely different and far larger plant ; it is 
very variable in size, some of the shoots on the same branch having leaves not half the length of others.

38. JUNGERMANNIA australis, Hook. fil. et Tayl.; ceespitosa, procumbens, caule ramoso, foliis imbri- 
catis suberectis rotundatis basi superne sublobatis inferne decurrentibus, stipulis bipartitis varie sectis seg- 
mentis plerumque basi dentatis, fructu in ramis brevibus terminali, calyce oblongo curvato subcompresso 
bialato bilabiato labiis rotundatis obscure crenatis. (Tas. LXV. Fig. III.) 
Has. Lord Auckland’s group and Campbell’s Island; moist banks in the woods and on trunks of trees. 
Cespites 2-3 unc. lati. Caules robusti, suberecti v. procumbentes, vage ramosi, nunc inter Hepaticas alias 
solitarii, sub 1 unc. longi, fusco-brunnei, sspe per totam longitudinem radicantes. Folia inferiora subpatentia, 
superiora imbricata, erecta, appressa, oblongo-rotundata, apicibus rotundatis integerrimis, cellulis plerumque majus- 
culis opacis. Stipule forma varie, plerumque oblongz et bifidee, utrinque basi unidentatze, segmentis divaricatis 
acuminatis, rarius subquadratee, quadrifidze, v. quadridentatee. Calyx exsertus, paulo curvatus, oblongus, basi cylindra- 
ceus, superne compressus, bialatus, alis subundulatis, ore obliquo bilabiato, labiis divergentibus obscure crenulatis. 
The fertile branches of this plant are short, with about five pairs of leaves, of which the upper, or perichetial, 
are oblong, and the corresponding stipule is the largest and most deeply laciniated. A broken capsule, found within 
the calyx, contained rounded angular seeds and slender much-twisted spiral filaments, each formed of a double helix. 
The barren plant strongly resembles some states of J. polyanthos, L., but in the fertile plant the oblong winged 
calyx, the included calyptra, and the more divided and toothed stipules abundantly distinguish it.
