FLOEA OE NEW ZEALAND. 



[Zichenes. 



14. Parmelia speciosa, Ach., Syn. Lich. p. 211. 

 Hab. Northern Island, barren, Colenso, etc. 



A species widely dispersed; among its habitats are Europe (middle and south principally, but also in Norway), 

 North America, Atlantic islands, Abyssinia, West Indies, Peru, Himalaya Mountains, East Indies, and New Holland.

Hab. Northern Island, barren, Colenso. 



Mr. Colenso's specimens being barren, it is difficult to speak certainly respecting them ; they appear to belong 

 either to P. obsessa, Ach., or to this species, but are rather more foliaceous than common. Apparently distinct from 

 the preceding by its appressed and far less foliaceous thallus, which bears usually, in its centre, elevated globose 

 soredia; yet Mr. Colenso's specimen looks a little ambiguous, and Dr. Montague remarks on a Tahiti specimen, 

 " in priorem (P. speciosam) abire videtur : an tantum confinis ?"— Ann. des Sc. Nat. t. x. (ser. iii.) p. 135. His work 

 on Cuba should by all means be consulted for this and the allied species. He has lately pointed out, in his ' Cryp- 

 togamia Guyanensis,' the probable identity of P. applanata, Pee, with P. picla, Sw. (not Montagne), in which I 

 entirely agree. Eound likewise in the West Indies, South America (the warmer parts), New Holland, Islands of 

 the Pacific, and the East Indies.

Universal throughout Europe and North America; found also in the Canary Islands, India, and the Antarctic 

 Eegions,

I have seen no specimens from New Zealand. 



§ 3. Zeoka, Pries, Syst. Orb. Veg. pr. p. — AmpHloma et Psoroma, Pries, Lich. Europ. 

 [The Lichens comprehended under AmpHloma and Psoroma seem too nearly allied to be divided into different 

 tribes ; some very eminent lichenists consider the species which Pries places under the latter tribe as mere varieties 

 of some of his Ampliilomata. As to the limitation of species, no tribe of Lichens is more perplexing ; it should be 

 well studied by southern botanists, for the temperate parts of the southern hemisphere, and especially (according to 

 Pries) the Islands of the Pacific, are the native seat of most of its species. We have received some specimens from 

 Mr. Colenso which we cannot name with satisfaction, and have preferred omitting them rather than hazarding very 

 dubious conjectures.]

Por this extraordinary form, see an admirable account by Dr. Montagne, in his ' Cryptogamia Guyanensis. '—A 

 Lichen of the West Indies and South America. I have not seen the normal form from New Zealand.
