FLORA OP NEW ZEALAND. 



\IIepaticce. 



Pallide fuscus. Caulk semipollicaris. Folia antice conniventia, cellulis hexagonis. AmpUgastria caule paulo 

 latiora, segmentis lanceolatis divergentibus. Spica mascula parvus, elongate, squamis imbricatis bidentatis. Odor 

 Piperis nigri. 



A small plant, with considerable resemblance to Geocalyx graveolens, Schrad., but with differently-shaped leaves. 

 The presence of male spikes, arising from the sides of the stems, is a character of no great generic value, for it has 

 been observed in Lophocolea and Chiloscyphus, although, in both these genera, it is decidedly exceptional.— Plate 

 XCVIII. Pig. 8 :— 1, a plant, natural size; 2, a portion of the stem, with leaves and male spike ; 3, portion of the 

 stem with stipule ; 4, portion of male spike, with leaflet detached ; 5, portion of leaf with cells -.—all magnified. 



16. Chiloscyphus laxus, Mitten ; caule repente subsimplici, foliis remotiusculis ovato-oblongis apice 

 varie tri-quadridentatis, amphigastriis parvis profunde bipartitis segmentis extus unidentatis. (Tab. XCIX.

Hab. Northern and Middle Islands: Auckland, Sinclair; creeping over Gotlschea appendicnlata, 



Jjyall. 



Amcene viridis, subpellucidus. Caulk elongatus, bipollicaris, parce ramosus, fragillimus. Folia explanata, 

 plerumque inasqualiter quadridentata, e cellulis majusculis laxis areolata. AmpUgastria quadrispinosa. 



The remarkably lax texture of the leaves of this species gives it more resemblance to some forms of Calypogeia 

 Trichomanis, than to any Chiloscyphm. Female flowers, in a very young state, have been observed on short and thick 

 lateral branches.— Plate XCIX. Fig. 1 :— 1, plants, natural size; 2, a portion of the stem with leaves, magnified. 



17. Chiloscyphus mtpimm, Hook. fil. etTayl.; caule repente vage ramoso, foliis ovatis apice obtusis 

 rarius bidentatis margine dorsali arcuato ventrali subrecto, amphigastriis ambitu suborbicularibus spinoso- 

 dentatis, medio sinu rotundo bidentatis, basi utrinque cum foliis subjectis anguste coalitis, "perianthio 

 campanulato ore fiexuoso-laciniato."-Z^. Jowrn. Sot. 1846, p. 284. 0. L. et N. Syn. Hep. p. 708. 

 (Tab. XCIX. Kg. 2.) 



Hab. Northern Island : Bay of Islands, Sinclair. Buahine range, Colenso. 



Pusco-virens. Caulis sesquipollicaris. Folia imbricata, explanata, subtruncata, undulata, margine dorsali 

 apicem versus paullulo recurvo, in ramis junioribus folia abnormalia varie bidentata, tenera, cellulis hexagonis. Am- 

 pUgastria majuscula, lateribus 5-6-spinosis. "Polia involucralia fere perianthii longitudine, alteram majus 3-4- 

 fidum, alterum minus bifidum. Amphigastrium involucrale brevius." Tayl. 



This species resembles C. polycladus, and agrees with it in having the dorsal margins of its leaves arcuate, 

 whilst the ventral are almost straight from the base to the apex, and at right angles from the stem ; the occasional 

 bidentation of the leaves seems similar to that which may be sometimes observed in the European C. pallescens. Dr. 

 Taylor has described the perianth, which resembles that of allied species.— Plate XCIX. Pig. 2 :— 1, a plant, natu- 

 ral size; 2, a portion of the stem with leaves and stipule, magnified. 



18. Chiloscyphus 'polycladus, Mitten; caule repente ramoso, foliis explanatis ovatis obtusis margine 

 dorsali arcuato integerrimo, ventrali rectiusculo basin versus dentibus parvis armato, amphigastriis circiter 

 sexspinosis utrinque cum foliis subjectis anguste coalitis.— Lophocolea polyclada, Hoot fil. el Tayl. Lord. 

 Jonrn. Sot. 1846, p. 367. G. L. et N. Syn. Hep. p. 697. (Tab. XCIX. Kg. 3.) 



Hab. Middle Island : Akaroa, Rami. 



Pallide fuscus. Caulk bi-tripollicaris. Folia laxe imbricata, margine ventrali basin versus sub-3-dentato, 

 dorsali apicem versus subrecurvo, tenera, cellulis rotundatis interstitiis angustis. AmpUgastria varia, pleraque sex- 

 spinosa. Flores fceminei in ramulo juvenili brevissimo laterales. 



A species with some resemblance to the European C. pallescens, Nees, but differing in texture and the form of 

 the leaves from it and all other species, including Lophocolea planiuscula, to which it has been compared.— Plate
