Hab. Northern and Middle Islands : Eay of Islands, /. B. II. Port Nicholson and Wairarape valley, 

 and Tararua mountains, Colenso. Port Preservation, Lyall. 



Ca?spitosus, fuscus v. purpureus. Caulis 1-2-pollicaris, flexuosus, radiculosus, sub perichsetio innovationibus 

 ramosus. Folia caulina sicca antice adpressa, humectata semiverticalia, patentia, margine ventrali incurvo ; infe- 

 riora bidentata sinu parvo obtuso, superiora vel margine ventrali dente parvo obtuso rudimentario vel sajpius (cum 

 margine dorsali) omnino integerrima. Folia involucralia exteriora majora bidentata denticulata, interiora minora bi- 

 fida varieque dentata. Perianthium obtusiusculum. 



The curious suppression of the ventral lobe in the perfect cauline leaves is peculiar to this species, but may also 

 occur in /. contractu, Nees, from Java ; for although sufficient specimens of this last have not been seen, to ascertain 

 if the lower leaves are bidentate, yet those of the involucrum resemble the involucral leaves of /. monodon, in being 

 cleft into two unequal parts.— Plate XCIV. Fig. 2 :— 1, specimens, natural size; 2, cauline leaves; 3, involucral 

 leaves ; 4, summit of stem with perianth :— all magnified. 



9. Jungermannia schismoides, Mont. — Flor. Anlaret. pp. 150, 434. I. clxi. f. 9. 

 Hab. Southern Island : creeping over Polyotus Magellanicus, Lyall. 



A very curious Lord Auckland Island and Fuegian species, of which three or four stems are all that have yet 

 been seen from New Zealand.— The areolation of the group of Jungermannia to which this and J. monodon belong, 

 differs considerably from that found in other sections ; the cells are rounded and remote, so that the leaves appear 

 dotted, nearly as in Sendlnera. Amongst the exotic allied species are— J", tubulosa, Nees (I. leucostoma and J. leu- 

 cocepMla, Tayl.), a common South American plant; J. aurita, Lehm. [? Sarcoscyplus auritm, Nees], from the Cape of 

 Good Hope ; /. Esenbeckii, Mont. ; J. imbricata, Wils., and J. involutifolia, Mont. ; J. crebrifolia, Hook. fil. et Tayl., 

 Flor. Antarct. (tab. clvii. fig. 9), in which species a distinct male spike has been once observed ; and J. biapi- 

 culata, Hook. fil. et Tayl., which seems intermediate between J. incumbens, L. et Ldbg., and J. piligera, Nees, species 

 which present but very slight distinctions. 



10. Jungermannia immdata, Hook. fil. et Tayl. ; caule procumbente radiculoso infra apicem innovante, 

 folds semiverticalibus orbiculatis imbricatis immarginatis patentibus, involucralibus majoribus patentibus, 

 perianthio breviusculo turbinate superne obtuse 4-5-plicato apiculato.— Lond. Joum. Bot. 1844, p. 559, 

 ex parte. (Tab. XCIY. Pig. 3.) 



Hab. Northern Island : Bay of Islands, in places subject to inundation, /. I). II. Cape Kidnapper, 

 Colenso. 



Ceespitosus, sordide viridis. Caulis 3-6-linearis. Folia subdensa, margine dorsali paullulo decurrente. Peri- 

 anthium immaturum turbinatum, apiculatum, demum 4-5-laciniatum. Capsula globosa. 



A small dingy species, with all the habit and appearance of J. nana, Nees, and /. splusrocarpa, Hook., but dif- 

 ferent from these and all other allied species, in its more turbinate perianths, and more opaque and denser structure. 

 No stipules are present ; those described as belonging to it, belong to a small species allied to /. serrulata, which is 

 intermixed with the specimens in Herb. Hook.— Plate XCIV. Fig. 3 :— 1, specimens, natural size; 2, a portion of 

 the stem with leaves ; 3, a leaf detached ; 4, a perianth and involucral leaves -.—all magnified. 



11. Jungermannia. rolata, Hook. fil. et Tayl.; caule implexo procumbente recurvo ramoso, ramis pa- 

 tenti-recurvis, foliis imbricatis erecto-patentibus secundis rotundatis concaviusculis integerrimis margine 

 antenore subdecurrente, amphigastriis parvis lanceolatis stepe obsoletis, perianthio obovato superne obtuse 

 tetragono quadrilaciniato laciniis inflexis, capsula globosa.— Lond. Joum. Bot. 1844, p. 560. G. L. et N. 

 Syn. Hep. p. 672. (Tab. XCIV. Pig. 4.)
