FLORA OF NEW ZEALAND. 



[ Hepaticce. 



This fine species varies considerably in the toothing of its leaves and stipules ; in some specimens the ventral 

 mar-in is entire, in others with more closely-set teeth than the dorsal ; their apices are also rounded or bidentate. 

 The dorsal bases of the leaves are generally combined, but in the specimen from Mr. Coienso they are separated by 

 one-fourth of the diameter of the stem, and placed one above the other. Colour varying from a pale green to a 

 deep brown.

Pallide viridis, tener. Caulis bi-triuncialis. Folia imbricata, marginihus dorsalibus suboppositis, ventralibus 

 plerisque quadrispinosis cum amphigastrio eoalitis. Amphigastria segmentis intus uni- extus bispinosis. 



This fine species resembles in some characters Lopkocolea trapezoidea, Mont., from Peru and Guadeloupe, but 

 differs in its more lax areolation and less ciliate stipules. From L. biciliaia, the only New Zealand species to which 

 it has any resemblance, it differs in the denticulation of the ventral margins of its leaves.— Plate XGVIII. Fig. 3 :—

7. Chiloscyphus aeuleatus, Mitten; caule repente ramoso, foliis imbricatis connatis ovatis apice shin 

 obtuso bidentatis margine dorsali medio unispinoso ventrali bi-tri-spoiioso, amphigastriis transverse oblongis 

 quadrispinosis cum foliis subjectis late eoalitis. (Tab. XGVIII. Pig. 4.) 



Hab. New Zealand: creeping over Eypopterygium continuum {Herb. Mitten). 



Viridis. Caulis pollicaris. Folia opposita, dorso marginibus eoalitis paullulo decurrentibus rectiusculis, apice 

 spinoso-bidentato. Amphigastria sequaliter quadrispinosa. 



A small but very distinct species, of which a few fragments are all that have yet been seen.— Plate XGVIII.

8. Chiloscyphus trispinosus, Mitten ; caule repente ramoso, foliis ovato-trapezoideis apice truncato- 

 bidentatis margine dorsali integerrimo ventrali medium versus unispinoso, amphigastriis bipartitis segmentis 

 bi- vel tri-spinosis basi utrinque cum foliis subjectis anguste eoalitis. (Tab. XGVIII. Pig. 5.) 



Hab. Middle Island: Bligb/s Sound; creeping over C. coalitus, etc., Lyall. 



Pallide viridis, subpellucida. Caulis pollicaris et longior, subsimplex vel ramis adproximatis, vage ramosus. 

 Folia explanata, imbricata, subopposita, dentibus brevibus spinosis, sublaxe reticulata, succosa, cellulis majusculis, 

 interstitiis angustis. Amphigastria brevia, sinu rotuudato, bipartita, basi in folia decurrentia. Odor gravis, aro- 



Very closely resembling C. odoratus, but a little more laxly areolate. Fructification unknown. The genus of this 

 and the preceding is hence uncertain ; they have more of the texture of Calypogeia Trichomanis than of any known 

 Lopliocolete or Chiloscyphi. The present species bears short male spikes scarcely protruding beyond the leaves, com- 

 posed of ventricose bidentate leaves, but without anthers.— Plate XCVIII. Fig. 5 :— 1, a plant, natural size; 2, 

 a portion of the stem with leaves ; 3, portion of leaf with cells -.—all magnified. 



9. Chiloscyphus odoratus, Mitten; caule repente vage ramoso crassiusculo, foliis oblongo-ovatis apice 

 spinoso-bideutatis, amphigastriis parvis profunde bipartitis segmentis extus unidentatis basi utrinque in folia 

 subjects auguste decurrentibus, perianthio campanulato ore dentata. (Tab. XCVIII. Pig 6.)
