64. JUNGERMANNIA clavigera, Hook., Muse. Exot. t. 10. 
Has. Campbell’s Island; on rocks, and on the trunks of trees. 
These specimens vary much in colour, in general they are of a richer brown, and less olivaceous than in the 
figure quoted, at other times they are nearly black.

Has. Lord Auckland’s group and Campbell’s Island; on the trunks of trees, and on rocks on the hills, 
abundant. 
The pericheetial leaves in this species are three, closely embracing the base of the calyx; the two lateral entire, 
obovate, having a strap-shaped acute curved inner lobe with reflexed sides; the third or stipular lobe is oblong, 
deeply divided into recurved linear segments, whose margins are uneven but not toothed. Calyx cylindrical and 
smooth for 4 way up, then ovate-rotundate, exserted, laciniated ; in the young state it appears terminated by a short 
tube. 
This species may be known from all others by the minute, divergent auricles below the leaves, and more par- 
ticularly by the plicate calyx. Montagne compares it with F. gracilis, nodulosa and integristipula, and adds that besides 
the difference in the calyx, the first of these has the involucral leaves serrated, and in the two others the stipules are 
entire. 
66. JUNGERMANNIA allophylia, Hook. fil. et Tayl. ; caulibus laxe dispersis flaceidis gracilibus flexuosis 
subramosis, foliis distantibus erecto-patentibus patulisve late ovatis obtusis acutisve integriusculis laxe reti- 
culatis, auriculis anguste oblongo-pyriformibus clavatisve incurvis a folio divergentibus, stipulis minutis bifidis 
segmentis lanceolatis seepius clavatis. (Tas. LXVI. Fig. I.) 
Haz. Campbell’s Island; on the hills, rare, growing with other Jungermannia. 
Caules 2-3 lin. longi, parce ramosi; rami alterni, siccitate subatri, madore lete sanguineo-purpurei. Folia 
forma sat varia, inferiora longiora, late ovata v. elliptica, obtusa v. rarius acuminata, integerrima v. bi-tridentata, 
cellulis pro planta maximis, auriculis pedicellatis majusculis erectis interdum deflexis. 
A beautiful little species and one of the smallest that is known of this subgenus; as in J. clavigera the lobes 
of the stipules are often replaced by club-shaped auricles.

67. JUNGERMANNIA rostrata, Hook. fil. et Tayl.; caule exiguo repente subpinnatim ramoso, foliis subap- 
proximatis patentibus rotundatis subapiculatis integerrimis lobo inferiore oblongo-lanceolato appendiculato, 
stipulis minutis rotundatis bifidis integerrimis, perigoniis obovatis rotundatis, perichzetiis oblongo-rotundatis, 
calyce obovato apice tubuloso basi angusto lineari. 
Has. Lord Auckland’s group ; on Parmelia enteromorpha, Ach. 
Cespites 1-2 une. lati, rufo-brunnei. Caules minuti, graciles. Folia rotundata, lobulo inferiore i magnitudine 
superioris ; perichetialia oblonga, apiculata, incurva, marginibus lobuli inferioris reflexis. Calyzx pericheetio bis longior. 
The present species bears much general resemblance to J. lobulata, Hook., differing from it in the smaller size, 
the narrow base of the calyx, which is of a different and less trigonous form, being wider above, and in the acute 
or apiculate leaves of the perichztium. It is as small as the previous species.
