EUPHRASIA SALISBURGENSIS FUNK, NATIVE IN IRELAND. 443 



viridia vel prtesertim in parte inferiore plantse rubescentia, glaber- 

 rima vel in pagina inferiore glandulis sessilibus vel in margine et 

 nervis prominentibns setulis minimis sparsis. Spica initio con-

 lanceolato-triangulares. Corolla parva fine antbesis G-8 mm. Ig., 

 labio superiore bilobo, lobis reflexis emarginatis vel denticiilatis, 

 labio inferiore 3-lobo, lobis emarginatis, subtusso/?(Hi ad basin pilosis. 

 Corolla plerumque albida labio superiore Cfcruleo, sed etiam tota 

 cffirulea, purpm-ea vel violacea. Capsula cuneato-elougata, trun-

"Distribution. — Scandinavia (Arctic Norway), (Nyman) ; Chris- 

 tiania (Blytt) ; Gotbland and Jutland ; [Ireland] ; in tbe mountains 

 of middle and Soutb Europe (Pyrenees, Sierra Nevada, Alps, Jura, 

 Carpathians, Balkans, Apennines, Corsica); not unfrequently de- 

 scending into tbe plains." 



The plant is eminently alpine. Gremli, in Excursionsfiora far 

 die Schweiz, gives " Alp., "Voralp., and Jura." Alp. implies an 

 altitude of about from 3400 to 4900 ft. above sea-level, and Voralp. 

 from 4900 to 7800 ft. I have myself found tbe plant at an altitude 

 of about 7800 ft. in Switzerland. 



For tbe synonymy I must refer to Prof. Wettstein's Monograph, 

 as it is too lengthy to insert here. 



As might be expected from an extensive range in altitude as 

 well as from a wide geographical range, several varieties have been 

 noticed. Prof. Wettstein says, p. 226, Munog., they are so numer- 

 ous that it would be useless to notice them all. He says, as a rule, 

 that in damp localities the leaves [and bracts] are broader, the 

 teeth shorter, and the whole plant smoother ; whereas in dry places 

 the leaves [and bracts] are narrower, the teeth longer and more 

 aristate, and the calyx more or less hispid. This description I can 

 endorse. 



Dr. Gunther Beck, in Verh. Zool. Bat. Ges. Wien, xxxiii, 226 

 (1883), in describing what he considered a new Euphrasia, which 

 he named E. invalis (placed by Wettstein with E. Salisburgensis), 

 groups the varieties of E. Salisburgensis as follows ; — 



«. vera. Caule elongato stepe filiforme, ramosissimo (ad 20 cm. 

 et ultra alto) ; ramis erectis, principali paulum brevioribus ; foliis 

 bracteisque lineari-lanceolatis, paucidentatis ; floribus remotissimis. 



{3. alpicola. Caule humili s^epe crassiore, simplice vel pauci- 

 ramoso (ut plurimum 10 cm. alto) bracteis latioribus subovatis, 

 spica densiore et breviore. 



Among some of the principal named varieties are E. exigua 

 Renter, E. Soyeri Timb. Lagr,, E. nivalis Beck., E. cupnea Jord., 

 E. Corsica Towns., E. Soubeiriniana Timb. Lagr., E. Salisburgensis 

 V. angustifolia Towns. ; but I would ngain refer to Wettstein's 

 Monograph for a more detailed account of these. 



On a future occasion I hope to be able to notice at greater
