THE LICHENS OF PERTHSHIRE 17 
Cromb.= Rev. James Crombie (1830 ?-1906). This abbreviation 
indicates his principal work, British Lichens: “a monograph 
of lichens found in Britain.” London, 1894. It contains 
many Perthshire records ; the collectors’ names are not given, 
ut all have been exam mined by the author, and probably a 
large ploportion collected by himself. Crombie contributed 
many notes on Perthshire lichens to various periodi icals. The 
most important, from our point of view are: ‘ New British 
Lichens,” J. Bot. 1868, 48 and 105; “ New hee Lichens, 
Grevillea, i. ai. : ii. 90, ini. 22, iv. 180, viii. 112, a3, # A 
New British Xylogr rapha,” 1b. iii. 128. ‘ Recent Additions to 
the British Lichen Flora,” J. Bot. 1882, 271; 1885, 194.
