ELOEA OF NEW ZEALAND. 



\_HepaticcB. 



Pallide viridis, tenera. Stipes pollicaris, tenuissime alatus, apice tripartitus et in frondera flabelliformem 

 dilatatus. 



Very closely resembling S.flabellata, but its fronds are of a very much thinner texture and have broader lacinia? 

 in proportion to their size.

 Bay, etc., Colenso. Auckland, Col. Bolton. 



All the specimens referred to this species correspond with each other in their dark green colour, and in having 

 the apices of their fronds attenuated. The margin appears to vary considerably, both in the size of the teeth and in 

 the prominence of the less pellucid cells, which form the margin itself: these cells are in a single row, and are pre- 

 sent in all the allied species, although easily overlooked. 



5. Symphyogyna sulsimplex, Mitten; fronde lineari simplici rarius furcatim ramosa inferne sensim in 

 stipitem attenuate margine integerrima. 



Hab. Northern Island : Bay of Islands, /. B. II. Auckland, Sinclair. Tree-ferns, East Coast, 

 Manawatu river, Colenso. Southern Island, Byall. 



Viridis. Frondes planse, sesquipollicares, 3 lin. latae, apice rotundatte, retusee, integerrima;, e cellulis hexagonis 

 areolatse, tetter®. Involucrum squamaaforme, dentato-lacerum, subbipartitum. Calyptra clavata, apice pistillis 

 abortivis coronata. 



The fronds of this species are unaltered in drying ; they appear to grow together in patches, and arise from a 

 creeping rhizoma, as is the habit of the allied species, although the specimens show scarcely any trace of that part. 

 Eeadily recognized from all its congeners by its linear simple fronds, excepting S. Gottscheana, M. et N., from 

 Mauritius, which (from the description) would appear to be very near to the present, but to differ in the repand 

 fronds and the presence of innovations from the emargination at their apices.

A cosmopolitan plant. None of the New Zealand specimens differ from British forms of this polymorphous 

 species, which seems to be common in all parts of the world. Besides the species common to Europe, the warmer 

 parts of the American continent produce several peculiar ones : of these M. procera is very near to M. furcata in size 

 and habit, but far more laxly areolate ; another is distinguished by its pinnated stems ; and a thud is described with
