Ul EUPHRASIA SALISBURGENSIS Funk, NATIVE IN IRELAND. By F. Townsend, M.A., F.L.S. (Tab. 363.) The Rev. E. S. Marshall has sent me specimens of a Euphrasia which are undoubtedly Euphrasia Salisbury ensis Funk. 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 from 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 Salishurgensis 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. Anther^e pilos^e. — Species Europae, insularum Azoricarum, Asiae extratropicse, Americas septen- trionalis, Australiae et Novae Zelandiae. Subsectio I. — SEMicALCARATiE Bcnth. Species hemisphaerii borealis, semper annuae, antherae mucronatae, duorum staminum posticorum breviorum loculus alter semper longius calcaratus. § 1. ParviflorcB. Foliorum longitudo latitudinem in maximo duplo superans. Capsulae margine semper erecto ciliatse. Corollae tubus fine anthesis non elongatus, itaque corollae omnes longi- tudine aequali. § 2. GrandiflorcB, Foliorum longitudo latitudinem in maximo duplo superans. Capsulae margine semper erecto ciliat^. Corollae tubus fine anthesis elongatus, itaque corollae initio anthesis breviores quam fine anthesis. § 3. Anyustifolim. Foliorum longitudo latitudinem 2-80-plo superans, folia itaque non ut in § 1 et 2 ovata, vel ovato-elongata sed linearia vel lanceolata. Corollae tubus in speciebus nonnullis fine anthesis non elongatus, in aliis elongatus. Subsectio 2. — Australes Benth. Species Australasicae vel Novo- JouRNAL OF Botany. — Vol. 34. [Nov. 1896.] 2 g
