FLORA OF NEW ZEALAND.

viscid matter. The medullary stratum consists of a few, very slender, distant, anastomosing filaments ; the exterior 

 of a reticulated plexus passing off into the periphery in moniliform filaments. Colour a purplish-red. It closely 

 adheres to paper in drying. Favellce suspended below the periphery, and enclosed in a dense plexus of filaments. 



2. Nemastoma ? attenuate, Harv. ; fronde (simplici ?) carnoso-membranacea succosa (strato medullar! 

 laxo) compressa lineari-attenuata, tetrasporis cmciatis sparsis. 



PIab. Jackson's Bay, Li/all. 



Of this we have only seen an imperfect specimen, about fifteen inches long, and a third of an inch wide in the 

 lower part, from which it gradually tapers to the apex. It is either the upper part of a simple frond, or a portion 

 of a branch of a slightly divided one. In either case it seems nearly related to N. intestinalis, but is of much thicker 

 and firmer substance, and quite distinct. 



3. Nemastoma pinnate, Hook. fil. et Harv. ; fronde plana carnoso-membranacea decomposite pinnata, 

 pinnis patentibus suboppositis lineari-lanceolatis basi et apice longe attenuatis, pinnulis filiformibus insequa- 

 libus subhorizontalibus, tetrasporis cruciatis sparsis. (Tab. CXX. JB.) 



Hab. Akaroa, Lyall. (Only one specimen.) 



Frond 4-5 inches long, and about as much in the expansion of the branches, undivided or once forked, closely 

 and pretty regularly pinnated throughout ; the pinnae distichous, opposite or subalternate, patent, much attenuated 

 to each end, two or three lines broad at the widest part, pinnulated with subhorizontal, ciliiform pinnules of irre- 

 gular length. Tetraspores cruciate, dispersed. Medullary stratum tolerably compact, passing off at the outward edge 

 into a network of anastomosing filaments, from which spring the moniliform peripheric filaments. Substance soft. 

 Colour a pale red.— It closely adheres to the paper in drying.— Plate CXX. B. Fig. 1, plant, natural size; 2, 

 section of the frond ; 3, a tetraspore : — both highly magnified. 



4. Nemastoma Daviesii, Harv. ; fronde stipitata foliacea gelatinoso -membra nacea ovato-lanceolata sub- 

 pinnata disticha, racbide simplici vel furcata, pinnis lato-lanceolatis vel subovatis basi et apice attenuatis 

 undato-crispatis patentibns dentatis v. ciliatis, favellis mimerosissimis per frondem sparsis. 



Hab. Tauranga, Bavies. Port Underwood, Lyall. 



Frond 6-8 inches long, expanded, leaf-like, more or less regularly pinnate, the principal rachis from i-lf- inch 

 wide, oblong or lanceolate, or irregularly sinuate, pinnated with numerous, lateral, ovato-lanceolate lobes, f inch to 

 an inch wide, 3-4 inches long, crisped and curled, irregularly dentate, lobulate or margined with ciliiform processes. 

 All the divisions taper to the base and apex. Colour purplish-red, changing; to blood-red. Substance gelatinoso- 

 membranaceous, closely adhering to paper. Favellce, on one of our specimens, very abundant. 



5. Nemastoma endiviqfolia, Harv. ; fronde e basi cuneata vage dicbotoma vel palmatifida et laciniata, 

 nunc anguste lineari multifida apicibus acutis tri-quadrifxtrcatis, nunc latifolia subpinnatim ramosa laciniis 

 lateralibus palmatifidis vel dicbotomis integerrimis vel eroso-denticulatis acutis vel abrupte truncatis, axillis 

 rotundatis, tetrasporis cruciatis sparsis. 



Hab. Blind Bay and Port Nicholson, Lyall. 



Excessively variable in form, and perhaps passing into N. Daviesii, from which, in its typical state, it looks 

 very different. A larger suite of specimens than we possess would be required to connect the various individuals we 

 have here brought together, more from the sum of probabilities than from exact evidence. Scarcely two are pre- 

 cisely similar. 



6. Nemastoma prolifera, Harv.; fronde (speciminibus maneis tantum visis) cuneata vage ramosa gela- 

 tinoso-membranacea viscida, lamina applanata folioiis parvis filiformibus vel cuneatis simplicibns multifidis- 

 que fimbriata et utrinque densissime obsessa. 



Hab. On stones, Akaroa, Lyall. 



A single broken specimen only, apparently the upper half of a frond, has been seen. It is about 8 inches Ion«-
