SCROPHULARIACE^: 233 



Euphrasia officinalis L. Common Eyebright. (Plate XXVIII.) 

 A small, branched annual, varying much in size, shape of leaves, 



size and colour of flowers, etc. Leaves small, sessile, opposite, ovate, 



deeply toothed. Flowers in loose, terminal, leafy clusters or spikes. 



The calyx with 4- pointed teeth. Corolla white or pinkish, streaked 



with purple and with a yellow spot in the throat. Capsule oblong. 



Sometimes in alpine regions the plants are only i or 2 inches high. 

 Pastures from the plains to the high Alps. July to October. 

 Distribution. Europe, Northern and Central Asia to the Arctic 



Circle. British. 



Euphrasia salisburgensis Funck. (Plate XXVIII.) 



A stiff, erect annual, often simple, though more frequently 

 branched, with prominent sharp teeth to the glabrous leaves, the 

 teeth being very large towards the base of the leaf. Flowers small 

 (6-8 mm.), usually white, with bluish upper lip or entirely blue, 

 mauve, or violet. Leaves often purplish. 



Pastures in the Alps and sub-Alps. July to October. 



Distribution. -Alps, Central and Southern Europe extending to 



Scandinavia and Corsica. Ireland. Particulars, with plate and 



map, of its distribution in Ireland are given in Mr. Praeger's very 



cheap and excellent little book on the Flora of the West of Ireland. 1 



Euphrasia minima Jacq. (Plate XXVIII.) 



A very small annual, yellow-flowered species, simple or branched 

 below. Leaves always obtuse, the lower ones with only I tooth 

 each side, the upper with 2-4 teeth. Bracts oval or oval-oblong, 

 spreading, with 3-4 teeth on each side. Corolla 5-6 mm. long, very 

 variable in colour and outline ; though usually yellow it is some- 

 times whitish or mauve or partly yellow and mauve. 



Pastures in the Alps and sub- Alps. July to September. 



Distribution. Alps, Jura, Auvergne, Pyrenees, mountains of 

 Central Europe and Asia Minor. Two or three years ago a form of 

 this plant was discovered on Exmoor, new to the British Isles. A 

 rather unlikely spot for the plant. The Exmoor specimens recently 

 seen by the author at the British Museum are not very typical of the 

 Continental plant, though they may be a form of it. 



Euphrasia lutea L. (Plate XXIX.) 



A very distinct annual species, formerly known as Odontites lutea 

 Reichb. Stems slender, branched, the branches being opposite and 

 spreading, finely pubescent. Leaves linear or linear-lanceolate, 

 scabrous, scarcely toothed, the upper ones and bracts entire. 

 Corolla bright yellow, with ciliated border. 



Dry, hot hills in the sub-alpine region. July, August. 



Distribution. Central and Southern Europe, Caucasus, Asia 

 Minor, Syria, Algeria.
