4. A. crassinervia (Bruch). Braithwaite, in Seemann's ''Journal 
of Botany," vol. viii., p. 95 (1870). 
Hab. Mountain rocks. Above Upper Lough Bray. I have not 
been able to understand this so-called species sufficiently to 
separate it with any confidence from A. rupestris. Specimens 
which I sent to the late Mr. "Wilson were so named by him, 
noted however as — *' Too near A. rupestris." 
I have specimens sent to me, which were collected in Ireland by Mr 
Gr. E. Hunt, and marked A. falcata, Schimper, which they proba- 
bly are ; but I think it better not to add this as a species at 
present to our list.
