FLORA OF NEW ZEALAND.

Apothecia unknown to me. Schaerer (Enum. Grit. p. 32) calls them " submarginalia limbo ciliato radiosa, 

 ciliis fugacibus." See also Hooker, Engl. El. vol. ii. pt. i. p. 306. The thallus of the New Zealand Lichen resembles 

 the figure in Engl. Bot. A less divided plant, more rugose and less rufous than 8. sylvatica, but probably not 

 distinct from it. See Fries, and the remarks on the preceding species. Cyphelke urceolate, white, then large, 

 explanate. Mr. Colenso's specimen is the only extra-European one which I remember to have seen. 



22. Sticta cimreo-glauoa, Tayl. ! ; tliallo tenui subcoriaceo suborbiculari lobato lobis snbascendenti- 

 bus amplis sinuatis (parum crenatis aut dissectis), supra glaberrimo glauco in arnbitu plerumque cinera- 

 scente humecto (saspe lsetissirne) viridi (prsesertim in junioribus) subtus pallido rufescente breviter ta- 

 mentoso, sorediis nullis, cyphellis pallidis urceolatis mox planis ssepe amplis, apotheciis appressis margi- 

 nahbus efc per thallum profusis minoribus, disco rufescente piano in senectute convexo et sajpe tuberculato, 

 margine tenuissimo crenulato subcolorato evanescente.— S. einereo-glauca, Tayl. I Lick. Antarct. n. 95. ul

Hab. Northern Island, Colenso, J. D. II. 



This species greatly resembles 8. linibata, and probably is not distinct from it. The lead-coloured soredia of 

 that species, however, are wanting, and the habit is somewhat different.— Plate CXXVII. C. Fig. 1, plant, natural 

 size; 2, portion of apothecium, vertically cut ; 3, asci; 4, sporidia :— all highly magnified. 



23. Sticta limbata, AcL, Meth. Lick. p. 280. Fries, Lick. Eur. p. 52. Sckar.! Exs. n. 557. A typo 

 paullulum differt 



V ar. sulflamda, Bab. ■ tliallo magis diviso lobis longioribus lsetius coloratis plus minus fusco-flavescen- 

 tibus subtus fulvescentibus, sorediis granulosis plumbeis magis eleratis. — Tie differt S. Thouarsii, Bel. 

 Stict.p. 90. t. 8./. 29. 



Hab. Northern and Middle Islands, on wood, Colenso, Lyall. (Barren.) 



This can hardly be distinguished with safety from the European Lichen. Delise's figure of 8. Thouarsii well 

 represents the ramification, and differs in nothing material except in the white soredia, which are decidedly lead- 

 coloured in the New Zealand plant. Specimens, which Dr. Hooker appears justly to refer to 8. Thouarsii, from the 

 Falkland Islands, are more stunted in growth, are thicker and browner, and have whiter soredia, but even in them 

 may be discovered a slight inclination to lead-colour in the younger stage. Apothecia unknown. 



D. Hirsute, Bab. — Frond foliaeeous, hied, often monophyllous, more or less hairy on the upper surface, espe- 

 cially when young. Apothecia distinctly and sulpersistently setose externally (not merely pubescent or sub- 

 ciliate). [This natural group includes 8. Rumboldtii, Hook., 8. cyathicarpa, Del., 8. cometia, Ach., but 

 passes into the preceding through 8. lomenlosa, Ach., which has the thallus smooth above, and the apo- 

 thecia less persistently hairy.] 



24. Sticta coriacea, Tayl.!; "tliallo coriaceo rufescenti-cinereo margine subtusque albido-villoso cellu- 

 loso-scrobiculato, lobulis margine decurvis subcrenatis subtus concoloribus, gemmis marginalibus planis 

 villoso-cihatis, cyphellis albis concavis marginatis, apotheciis sessilibus concavis extus villosis disco rufes- 

 centi-nigro margine mcnvTO."~Tayl. Lick. Antarct. n. 90. ut supra. (Tab. CXXV. A.) 



Hab. Northern and Middle Islands, Colenso, J. I). II., Lyall. 



" Several inches wide ; thallus thick, not shining, pale ochrey-brown, very uneven, the central parts ascending, 

 the margins deflexed," Tayl. 1. c. A very distinct species from every other in this enumeration ; the thallus has 

 somewhat the habit of 8. glomulifera, Delise. 8. Eumloldtii, Hook., and S. cyathicarpa, Delise (8. Kunthii, Hook.), 

 are allied, but abundantly different. So also is 8. cometia, Ach., but, judging from Delise's ample description and 

 neat figure, it cannot possibly be the same. 8. obvolula, Ach. (non Delise), which is undoubtedly 8. lunula, Mont. 

 Voy. au Pole Sud, p. 18S. pi. 15. f. 2 (opt.), resembles the present plant much, but the cyphelke are punctiform,
