FLORA OF NEW ZEALAND. 



145 



Fusco-viridis. Caules semipollicares, arete repentes vel interdum areuati, apicibus radicantibus. Folia expla- 

 nata, imbrieata, ovata, margine dorsali subrecurvo, superne sensim majora. Torus longissimus, longitudine plantam 

 totam sequans, anguste claviformis, radiculis parvis obtectus. 



An interesting little species, allied to 67. Bustillosii, Mont., from Peru, but readily distinguished from all others 

 yet known, by its very long torus. The New Zealand specimens are rather smaller than those from Swan River, 

 . but correspond in all other respects ; and a reference to the figure will show that it cannot be referred to Riccia. — •

Gen. VIII. SACCOGYNA, Dumort. 



1. Saccogyna australis, Mitten; caule repente ramoso, foliis imbricatis ovatis apice obtusis minute 

 bidentatis integerrimisve, amphigastriis parvis bidentatis basi in folia subjecta anguste decurrentibus, peri- 

 anthiis carnosis radicnlosis. (Tab. C. Fig. 1.) 



Hab. Northern Island : forests, Tararua, Colenso. 



Sordide flavo-viridis. Folia explanata, margine dorsali subrecurvo. Amphigastria fere ad basin bipartite, 

 segmentis ovato-laneeolatis, cauli parallels. PeriantMum 2 lin. longum, ore foliolis tribus dentatis coronato. Ca- 

 lyptra perianthio omnino adnata. 



Closely resembling the British S. viticulosa in size, habit, colour, and the minutely punctulate surfaces of 

 its leaves, but differing in its bipartite stipules and minutely bidentate and narrower leaves, the cells of which are 

 nearly twice the size of those of the European plant. The internal structure of the perigynium, or torus, differs 

 from that of 8. viticulosa in having the calyptra adnate with it throughout. There is no involucellum surrounding 

 the base of the fruit-stalk in this species, nor does there appear to be any such part present in the torus of Gym- 

 nantke saccata ; what seems to have been mistaken for it is only the slightly expanded base of the fruit-stalk at its 

 point of union with the bottom of the torus. — So few examples of the perfect torus of Saccogyna viticulosa have 

 been examined, that it appears premature to deny the presence of an involucellum in that plant ; it is stated in the 

 'Synopsis Hepaticarum' nearly to equal the height of the combined part of the calyptra. — Plate C. Pig. 1 : — 1, a 

 plant, natural size; 2, a portion of the stem with leaves and stipule ; 3, portion of the leaf with cells ; 4, a portion 

 of the stem and section of the torus with part of the fruit-stalk : — all magnified.
