Andre<S(S with nerved leaves, which were only numbered ; 

 these belonged to three species, viz. : 



1. Andre^ea falcata, S chimp,, forma minor. 



Hab. Ben Voirlich, by Loch Lomond, in Scotland, July 1865 (G. E. 



Hunt, No. 4). 



This species is easily distinguished from the following by its 

 very falcate leaves, from a broad, nearly round and concave base, 

 very abruptly narrowed into a distinctly repand subula, but re- 

 sembles it in the not at all glossy black colour of the whole plant, 

 and in the rather ill- defined nerve, occupying only the middle 

 third of the subula. By these characters they are both well 

 distinguished from the probably more common A, crassinervia, 

 Bruch. 



2. Andre^a Rothii, W. h M, (A, rupestris. Roth, ^^^« Beitr/x. 

 pp. 232-36, exch synon. 1802). 



Hab. North Wales, Capel Curig, July 1863 {Whalley, No. 6); Devver- 

 stone rocks, Devon, May 1867 {Holmes, no. 8); Mazebeck Sears, 

 Yorkshire, June 1856 (J. G. Baker, no. 10) ; Snowdon, Crib-y-Discl, 

 June 1865 {W. P. Schimper, no. 14). 



Var. GRIMSULANA, C Muell, (A. grimsulana, Bruch, MS.). 



Hab. Brandsby Falls, Yorkshire, May 1858 (J. G. Baker, no. 7). 



3. ANDREiEA CRASSINERVIA, Bruch {ill Denksch. Akad. Munch. 

 1828, p. 279. no. 1, tab. 10). 



Hab. Lancashire, Staley Brushes, April 1864 {Whitehead, no. 1); 

 Entwistle, December 1865 {Whitehead, no. 2); Snowdon, North 

 Wales, May 1853 {Nowell, no. 5), August 1860 {Whitehead, no. 3); 

 Hebden Bridge, Yorkshire, July'1865 (Hmw^ no. 9) ; Soccoth Hill. 

 Arrochar, June 1865 {M'Kinlay, no. 11); Loch Kandor, Aber- 

 deenshire, July 1868 {Hunt, no. 12) ; Beddgelaert, North Wales, 

 August I860 {Hunt, no. 13). 



Is easily distinguished from the foregoing by its being a more 

 robust plant, somewhat glossy, and with the nerve much better 

 defined, thicker and more prominent on the back, and also form- 

 ing by itself the whole upper part of the subula. When it
