Ihfourii. I may just add that 8. Dufourii occurs in the Hookerian Herbarium, marked « Scotland/' to which Dr 

 Taylor has written the name S.fimbriata, Tayl. S.filicina occasionally bears black cephalodia, which greatly re- 

 semble the apotheeia of a Cetraria ; we have added a figure of this state. The young plant bearing these has been 

 called Cetraria lacera by Dr. Taylor (in Hook. Loud. Journ. Bot. Dec. 1844). The branches in this species occasion- 

 ally take root and form another plant. We have seen no specimens of true S.filicina except from New Zealand • 

 it is said to be found elsewhere, among other places, in Jamaica; but we rather suspect that this may be our Sticta 

 Seemanni, of which a figure will soon be published in the < Botany of the Herald,' and to which 8. marginifera, 

 Mont.! (barren), may possibly be referred.f 



9. Sticta Mifrom, A. Rich! M. N.Zel.p. 27. t. 8./. 2; stipite lignoso crasso brevi, thallo coriaceo 

 glaucescente flabellato sinuato lobis linearibus palmatis corniculatis integerrimis subtus glabriasculo s. bre- 

 viter tomentoso plus minus obscuriore subreticulatim costato, cyphellis amplis lutescentibus expansis, apo- 

 theens rubns (pallidis s. obscuris) appressis planis demum convexis, margine tenui evanescente. 



Var. a. ocAwleuca, Bab.; thallo ocliroleaco s. glauco, costis validioribas, subtus pallida, apotheciis 

 flavo-rubris. 



Var. j3. Menziesii; thallo crassiore flavo-fusco subtus branneo nigricante costis obscurioribus, apothe- 

 ciis fusco-rubns s. mgricantibus.— S. Menziesii, Eook.fd.! FL Antarct. p. 198. (Tab. CXXII.) 



Hab. Northern and Middle Islands, on trees, earth, and stones, Menzies, Be Belligny (Herb. Mas. 

 Par. n. 57), Colenso, etc. 



A well marked species, but varying in colour, and in the length of the stem, which is sometimes almost obso- 

 lete. It u possible to select specimens of a and B which look very different, but an inspection of a numerous suite 

 will convince any one that there are no limits whatever between them. S. macrophylla varies exactly in the same 

 way, and its dark form is called 8 badia by Mougeot.— Found also (as it appears) in Lord Auckland's Group and 

 in Owyhee, but the specimens in Herb. Hook, are incomplete.— Plate CXXII. Var. Menziesii. Fig. 1, young 

 state; 2, old state, natural size; 3, vertical section of under surface of thallus ; 4, section of apotheciuirT; 5,' ascus; 

 6, sporidia ; 7, portion of subjacent stratum -.—all highly magnified. 



B. Dam^cornes, Bab.— Thallus stemless ; lohes repeatedly forked and comiculated, nearly linear, margins not 

 smuated and dissected. Apotheeia not hairy. [The species of this section are so nearly allied, that it is 

 next to impossible to limit them. See J. D. Hook. Fl. Ant. p. 527. The species of Delise's work, 

 n. 29-40, appertain for the most part to this division, which forms in itself a tolerably natural section' 

 but merging into the preceding and following one.] 



* Thallo profunde scrohiculalo. 

 10. Sticta Iiic/iardi, Mont.! ut infra; thallo subcoriaceo s. submembranaceo molliusculo opaco dicbo- 

 torne lacimato, laciniis elongatis divergenti-corniculatis, apicibus loborum acutis s. rotundatis s. emargi- 

 nato-truncatis supra pallido glaucescente vel viridi rufescente subconcentrice scrobiculato, subtus plus minus 



f Since the greater part of this account of the New Zealand Lichens was written, I have received from Dr. 

 Montague his diagnosis of new species of Lichens in Chili, and remarks on other described plants of the same Order 

 (Ann. des Sc. Nat. ser. m. vol. xviii.). He remarks of S.filicina that it would take a volume to describe its forms, 

 and unites with it Sticta Bufourii, Del, 8. marginifera, Mont., S. hypopsila, Mont, (which he considers probably the 

 same as S. glaberrima, Laur., remarking "transitus ad S. damacornem"), and S. latifrons, A. Kick. The specimens 

 which I have seen would not have led to the same conclusion as my learned friend has arrived at, but I do not at 

 all deny the possibility of his views being right, and commend them to the attention of the colonial student. 

 Still I have, on the whole, preferred to let the above remarks stand as they were originally written, acknowledging 

 at the same time that they probably require modification. The liability to error is in cases of this 'kind very o-reat° 

 and no one, who is only acquainted with a few dried specimens, ought to lay too much stress on his own views!
