All those authors who have mentioned this species call attention to its 

 resemblance with yllccioria oclirolciica and A. sarmentosa. 



It seems to me that it is well separated from A. sarninitosn by its 

 whole habitus, especially its manner of branching, and by the rarely wanting 

 blackish stripes which arc, however, only quite exceptionally developed at 

 the apices. It is evidently more related to A. ochroleuca, differing from 

 that species in the concolorous apices of its prostrate thallus, and the 

 ibveolate, usually more or less widened thallus. 



It is more variable than any other Alccforia in Norway. If the thallus 

 is broadly ligamentous and very foveolate it was called Alcctoria vc.xillifera 

 by Nylander in Kihlmax Zur Flechtenflora der Halbinsel Kola p. 48 (with 

 plate), cfr. also Sern ander: Om nâgra former for art- och varietets-bildning 

 hos lafvarne, p. 178 and' pi. IIL 



My rich material exhibit evei-y transitional stage between the vcxilli- 

 fcm and the ciiiciiiiiata, and 1 agree with Sernander that the former is 

 only a 'fasciation' of the type. The vcxillifcra is not common in Norway. 



Some plants are almost unbranched, others very intricately branched 

 with almost crinate branches. Sometimes plants of the former type develop 

 small dense clusters of the latter type. 



Alcctoria cincinnaia is especially found on maritime rocks in Northern 

 Norway (Norw.: 'Næringer' I, it is quite a type plant for these promontories. 

 It is also — though rarely — found on the mountains, in Northern as 

 well as in Southern Norway. In Finland it has been recorded from Aland 

 and in Sweden from the islands near Stockholm; in Southern Norway it 

 has not yet been recorded from maritime stations. 



It is impossible to overlook the analogy betw^een this species and 

 Alcctoria jiibata f. chalybciforinis which has also a foveolate, and frequentl}' 

 a broader thallus. But having seen A. ciiiciiiiiata in nature I think it impos- 

 sible to doubt of its specific rank.
