FLORA OF NEW ZEALAND.

Gen. IY. CETRARIA, Ach. 



1. Cetraria glauca, Ach., Syn.p. 227. A. Cimn. Comp. to Bot. Mag. v. 2. p. 331. Baoul, ut supra. 

 Fl.Anl.p. 524. 



Hab. Middle Island, D' Urvitte. 



I have seen no New Zealand specimens. For the geographical distribution see Dr. Hooker's remarks, Fl. 

 Antarct. p. 523, and my own in Seemann's Bot. of the Herald, p. 47. 



2. Cetraria scepincola, Ach., Syn. p. 226. Fl. Ant. p. 524. 



Hab. Fragments of this species occur on a specimen of Sticta crocata, gathered on wood at Auckland 

 by Dr. Sinclair. Rather a large form ; barren ; not pulverulent. 



I do not well understand how this species differs from the olive form of C. glauca, unless it be in the paler 

 under surface. See Fries (Lich. Eur. p. 39). The present specimens are pale below, but blotched (through age?) 

 with black. Found in Central and Northern Europe (" Switzerland to Lapland," Scharer), in the higher and 

 Arctic latitudes of North America, also in the Straits of Magellan (Montagne). 



3. Cetraria aculeata, Eries, Lich. Eur. p. 35. Fl. Ant. p. 524. Cornicularia, Ach., A. Cunningham, 

 ut supra. 



Hab. Middle Island, If Urvitte. 



I have seen no specimens. States of Cladonia aggregala are very easily mistaken for it ; but there is no reason 

 why it should not occur in New Zealand, being found in various places in the Antarctic regions, as well as over 

 Central and Northern Europe and Arctic America. Cetraria lacera, Tayl. ! Lond. Journ. Bot. ut supra, is only a 

 state of young Sticta fdicina, bearing eephalodia : cyphellas are present. 



Gen. V. PELTIGERA, Hoffm., Fries. Peltidea, Ach. 



1. Peltigera polydactyla, Hoffm., Fries, Inch. Bur. p. 46. 



Hab. Middle Island, liaoul, lyall. "Very abundant in New Zealand" {Fl. Antarct. p. 524). 



2. Peltigera canina, var. pusilla, Eries, Lich. Eur. p. 45. Fl. Ant. p. 524. P. spuria, Ach. Meth. 

 lich. p. 283. t. a.f. 2. 



Hab. Northern and Middle Islands, Colenso, liaoul. 

 Specimens small, well-marked. 



3. Peltigera nifescens?, Hoffm., Fries, lich. Fur. p. 46. 

 Hab. Northern Island, Colenso. 



Mr. Colenso's specimen appears to belong to this species ; it is full of apothecia, but does not exhibit the 

 thallus very distinctly. It is probable that this and both the two preceding may be found in the temperate and 

 alpine regions of both hemispheres, in all latitudes, but they seem to be more rare within the tropics. See Hook. 

 Fl. Antarct. p. 524-5. Seemann's Bot. of Herald, p. 48. Linnasa, 1843, p. 15, etc.— Very probably other species 

 of this genus will be found in New Zealand. 



Gen. YI. NEPHROMA, Ach. 



1. Nephroma auslrale, A. Rich., Fl. Nov. Zel.p. 31. Toy. de VAstrol.pl. 9.f. 2. Mont.! Fl. Fer- 

 nand. #.66. 



Hab. Northern and Middle Islands, If Urvitte, Colenso, Lyall. 



A small species, and well marked, with the habit of N. resupinatum, but having the colour of N. polare above, 

 with the under side smooth and pale. Found also in Juan Fernandez and Tasmania.
