 Hab. Throughout the Islands, abundant, Cunningham, etc. 



A large and handsome species, of which some specimens, gathered by Mr. Stephenson, are more than six inches 

 high ; it is found in Java, and specimens, said to be from Jamaica, are in Herb. Lindenberg. 



14. Plagiochila Sinclairii, Mitten ; ramis erectis parce divisis strictis, foliis laxe imbricatis patenti- 

 divergentibus semiovato-oblongis obtusis margine dorsali reflexis mtegerrimis ventrali apiceque dentato- 

 ciliatis, perianthio temiinali oblongo-obovato compresso ore truncate dentate. (Tab. XCVI. Tig. 5.) 



Hab. Northern Island : Auckland, Sinclair. Bark of trees, Tehawera, Colenso. 



Rami 4-5 unc. longi, innovationibus parce ramosi. Folia inferiora rotundata, remotiuscula, superiora sensim 

 majora, laxe imbricata, margine ventrali ubique dentato-ciliato. Perianthium bilineare, compressum, ore dentibus 

 longioribns ciliatum. 



Very different from any other New Zealand species, and, so far as can be judged from the figures in Linden- 

 berg's ' Species Hepaticarum,' more nearly allied to the West Indian P. Breuteliana and P. flaccida, Ldbg. The 

 more numerous and much more slender ciliiform teeth, as well as the form of the leaves and perianth, abundantly 

 distinguish the present from the larger forms of P. delioidea, to which it has some external resemblance.— Plate 

 LCVI. Fig. 5 : — 1, a specimen, natural size; 2, a portion of the stem with leaf; 3, a perianth and involucral leaf:

 coideis, foliis ovatis late sernicordatisve apice subquadratis margine dorsali parum recurvo integerrimo ven- 

 trali apiceque spinuloso-dentato, involucralibus conformibus argutius dentatis, perianthio ovato compresso 

 ore denticulato. (Tab. XCV.) 



Hab. Northern and Middle Islands : ravines near Wellington, Stephenson. Thomson's Sound, Port 

 Cooper, and Port Nicholson, Lyall. Euahine mountains and East Coast, Colenso. 



Rami 4-8-pollicares. Folia imbricata, apice subtruncata vel quadrata. Perianthia numerosa in ramulis pro- 

 priis brevibus. 



A splendid species, unsurpassed in its noble size and fern-like ramification. In habit it appears to agree with 

 P. Javaniea, Nees et Mont., and P. Belangeriana, Ldbg.; but it differs from both in its shorter and wider leaves, and 

 in its ovate perianth, which has its mouth somewhat contracted, and its lips rounded. It appears to be common in 

 New Zealand, and small specimens gathered in Lord Auckland's Islands were distributed as P. aculeata, TayL—

Hab. Common throughout the Islands, Menzies, etc. 



Very common, but only in New Zealand, and generally fertile. It has a proliferous habit, especially the male 

 plants, and varies but little, except in size. The branches spring from near the same part of the stem, and being 

 nearly of equal length, the fronds have a flabellate outline. P. Chonotica, TayL, is nearly allied to P.gigantea, and 

 corresponds in every respect with P. Neesiana, Lind. Sp. Hep. 1. 13.

 Hab. Middle Island : Dusky Bay, Menzies. Port Preservation, Lyall. 



Dr. Lyall's specimens are much smaller and less branched, they also produce' a few flagelte, but in all other 

 respects correspond with those of Menzies. P. minutula (PI. Antarct. t. clvii. fig. 1) may perhaps be a youno- state 

 of this : the outline of the leaves is very similar, though erroneously described as obovate, but their areolation is not 

 exactly the same.
