FLOE A OF NEW ZEALAND. 



[Lichenes. 



bright yellow. A specimen of the former in my herbarium (from Aiton's collection) is named " L. berberinus, Men- 

 zies."— Plate CXXV. A. Fig. 1, plant, natural size ; 2, apothecia; 3, vertical section of portion of apothecmm ;

Hab. New Zealand (probably from Akaroa), llaoul. 



Of this I have seen no New Zealand specimen, except a small (unnamed) fragment from the Paris Museum, 

 which seems clearly to belong to it.-Widely dispersed over Western and Central Europe (Spain to Norway, Fries), 

 the Canary Islands, Northern and Arctic America; found also in the Himalaya Mountains (Winterbottom !) and 

 Peru (Florke). 



26. Sticta Montagnei, Bab. ; thallo submembranaceo latissimo glauco subrufescente (humecto non 

 mutato) foliaceo corrugate, lobis subsinuatis rotundatis crenatis ad margines squamulas foliaceas gerentibus 

 subtus nudiusculo subferrugineo passim nigricante, cyphellis saepius absentibus passim vera occurrentibus 

 minutis prominentibus albidis clausis subobsoletis, strato medullar! albo, apotheciis amplis liberis ubique 

 sparsis seepe confertissimis disco nigro, margine inflexo saspe lacero subserrato folioloso. 



Hab. Northern and Middle Islands, on wood, Sinclair, Lyall. 



After a good deal of hesitation and consideration, I incline to Dr. Hooker's view, that this Lichen must be 

 compared with 8 herbacea, which it resembles on many accounts, but is at the same time most abundantly distinct. 

 The apothecia are those of a Sticta, bursting from under the gonimic stratum, and remarkable for their crown-bear- 

 ing leafy margin, which is singularly iniiexed, so as often to conceal the disc in great measure. Sporidia mmute, 

 contained in elongated asci, subfusiform, not very regular in form, brown, not containing septa, so far as I could 

 observe. The thallus also sometimes has manifest traces of cyphelte, but other specimens would lead any one to 

 consider them a Parmelia, as Dr. Montagne was disposed to do, to whom I dedicate the plant, which seems to be 

 undescribed.

Hab. Northern Island, on bark, Colenso. 



The pulvinuli which are ordinarily found in the European form are wanting in Mr. Colenso's specimens. 

 Tuckermann observes that they are always absent from the North American form. This species again is found over 

 a very wide tract of country, not only extending over the great continents just mentioned, but also found in St. 

 Domingo, according to Delise. We do not, however, remember to have seen specimens from any other part of the 

 southern hemisphere, except New Zealand.

Hab. Probably common everywhere. Northern and Middle Islands, Colenso, ILooJcer, Lyall. 

 A variable species, of which the two following Lichens are perhaps but forms : they have, however, been mi- 

 nutely distinguished by Dr. Taylor in the Irish Flora. P. perlata and P. reticulata have the " buds (soredia) in mar- 

 ginal powdery clusters." P. proboscidea, TayL, has the " buds on thallodal solid podetia," i.e. is isidiophorous ; and 

 P. perforata, Ach., has the thallus very thick and tough, reticulato-rugose, void of soredia and isidiophorous processes,
