subtended by another pair, also combined to about their middle, hence forming an almost perfect perianth, as in 

 Jungermatmia. The transition from Gymnomitrium concinnatum, through SarcoscypMs, to the Jungermannia; with 

 perfect perianths, is so gradual, that the former should rather be considered as a less perfectly developed species of 

 Jungermatmia; it is hence probable that all the species referred to Gymnomitrium in the ' Synopsis Hepaticarum' 

 must be excluded, excepting G. concinnatum and G. coralloides ; the rest belong to Gymnanthe and Fommbrpnia. 



2. Jungermannia puMetta, Hook. Mime. Exot. i. 94. G. L. etN. Syn. Hep. p. 129. 



Hab. Northern and Middle Islands : Dusky Bay, Menzies. Port Preservation and Port Nicholson ; 

 growing amongst Tricliocolea lanata (Hook.), Lyall. Auckland, Sinclair. 



A highly curious species.— Leaves of a very thin texture. Perianths trigonous above ; mouth truncate, fringed, 

 with long, slender teeth, which stand out in all directions. 



3. Jungermannia quadrifida, Mitten ; caule repente adscendente ramoso inferne stolonifero, foliis pa- 

 tentibus ad medium 4-fidis laciniis lanceolatis integerrimis vel in caule fertili subdentatis, amphigastriis 

 conformibus, perianthio elongate superne trigono ore truncate laciniato-dentato, foliis involucrahbus am- 

 phigastrioque argute dentatis. (Tab. XCIV. Pig. 1.) 



Hab. Northern Island : Patea village ; creeping on the earth with Marchantia macropora (Mitten), 

 Colenso. 



Vagans, sordide fusca, apicibus lutescentibus roseo-tinctis. Caulis 4-8-linearis, inferne parce radiculosus. 

 Folia verticalia, sinubus obtusiusculis. 



Allied to J. trichophylla, and intermediate between that and J.pulchella, which it resembles in its quadripartite 

 leaves and stipules, trigonal, truncate perianth, and in the not inflexed lacinias which surround its mouth. J", quadri- 

 partita, Hook. (Muse. Exot. 1. 117), appears to be nearly allied to this, but sufficiently distinct.— Plate XCIV. Fig.

Hab. Northern Island : Bay of Islands, /. I). II. Near To Ante, Colenso. 



5. Jungermannia colorata, Lehm.— G. I. etN. Syn. Hep. pp. 86, 673. Fl. Antarel. pp. 149, 429. 

 Hab. Northern Island : summit of liuahine mountains, and snow-water rills, summit of Oparapara, 



Colenso. 



Probably common on the mountains of New Zealand, as it occurs in all the Antarctic regions,

 G. L. et N. Syn. Hep. p. 3. 



Hab. Northern Island : summit of Euahine mountains, Colenso. 



Corresponding entirely with British specimens. This species was gathered on the top of Mount Forster, in 

 Hermite Island, Cape Horn, but was overlooked in the enumeration of the species from that locality. 



7. Jungermannia jiexieaulis, Nees, in Linnea, v. 6. p. 604. — 0. L. et N. Syn. Hep. p. 87. 

 Hab. Northern Island ; amongst Plagiochila falcaia, Hook. Tararua mountains, Colenso. 



A pretty species, with much the habit of J. colorata, having its stems straight or elegantly flexuose. The spe- 

 cimens agree entirely with authentic ones from Java, and with others from the Sandwich Islands. 



8. Jungermannia monodon, Hook. fil. et Tayl. ; caule procumbente flexuoso radiculoso e ventre inno- 

 vante parce ramoso, foliis adscendentibus vel semiverticalibus arete imbricatis homomallis ovato-lanceolatis, 

 margine ventrali dente breviore lobuliformi terminate [rudimento lobuli folii alterius deficientis], amphi- 

 p-astriis nullis, perianthio oblongo quadriplicate, ore connivente ciliato, foliis involucralibus polymorphis
