EUPHRASIA SALISBURGENSIS Funk, NATIVE IN 

 IRELAND. 



By F. Townsend, M.A., F.L.S. 



(Tab. 3G3.) 



The Rev. E. S. Marshall has sent me specimens of a Euphrasia 

 which are imdoubtedly Eiiphrasia SalisLiur/eiisis Fuuk. They were 

 gathered by him on limestone rocks south of Lough Mask, Co. Mayo, 

 on July 15th, 1895, his reference number being 1607. Mr. Marshall 

 writes that he believes the plant was fairly plentiful where found, 

 about two miles south of Clonbur, on low limestone cliffs bordering 

 Lough Mask, at an altitude of fi'om 80 to 90 ft. above sea-level. 



This discovery adds another species to the interesting group of 

 plants (members of an ancient and existing continental flora) still 

 flourishing on the Continent, but as regards the British Islands 

 only surviving at the present time in Ireland, and principally in the 

 western and south-western counties. 



Euphrasia Salisburgensis Funk is a member of a distinct division 

 of the genus hitherto unrepresented in the British Islands. It is 

 distinguished from all other British forms by its narrow leaves 

 and bracts, with comparatively few lateral usually aristate teeth. 

 The Irish plant has only two teeth on either side of the upper leaves 

 and bracts. 



Prof. Wettstein, in his monograph of the genus, published this 

 year, and noticed at p. 369 of the Journal of Botany for August, 

 divides all the forms of the genus into sections, subsections, and 

 groups, as follows : — 



Sectio I. — EuEUPHRAsiA Wettstein. Folia indivisa, dentibus 

 utrinque acutis vel obtusis 1-10. Antherte pilosfe. — Species 

 Europfe, insularum Azoricarum, Asise extratropicse, Americae septen- 

 trionalis, Australite et Novse Zelandise. 



Subsectio I. — SEMicALCARATiE Bcnth. Species hemisphrerii 

 borealis, semper annua, antherse mucronatae, duorum staminum 

 posticorum breviorum loculus alter semper longius calcaratus. 



§ 1. Parvijiora;. Foliorum longitudo latitudinem in maximo 

 duplo superans. Capsulte margine semper erecto ciliatfe. Corollne 

 tubus fine anthesis non elongatus, itaque coroilaB omnes longi- 

 tudine aequali. 



§ 2. GrandiJiorcB. Foliorum longitudo latitudinem in maximo 

 duplo superans. Capsulse margine semper erecto ciliatcTB. Corolla 

 tubus fine anthesis elongatus, itaque corolla initio anthesis breviores 

 quam fine anthesis. 



§ 3. AngustifoUiB. Foliorum longitudo latitudinem 2-30-plo 

 superans, folia itaque non ut in § 1 et 2 ovata, vel ovato-elongata 

 sed linearia vel lanceolata. Corolla tubus in speciebus nonnuUis 

 fine anthesis non elongatus, in aliis elongatus. 



Subsectio 2. — Australes Benth. Species Australasicse vel Novo-
