MONOGRAPH OF THE BRITISH SPECIES OF EUPHRASIA. 425 



plant have usually only three teeth on either side, and the lowest 

 flower is rarely below the middle of the stem. Kerner distinguishes 

 E. micrantha Eeich. as distinct by the short awn-like ending of the 

 upper bracts, by its shorter calyx, the teeth not exceeding the 

 capsule ; but these are characters frequently found in Scotch 

 specimens of K. (jracilis, and connected by every intermediate form. 

 Prof. Wettstein says that in the South it flowers frequently in June, 

 iu Sweden and Norway in August and September. In Scotland 

 I have found it in flower in May. 



Small forms of E. nemorosa may be mistaken for E. gracilis, but 

 the shiuing upper surface and erect position of the leaves and bracts 

 will distinguish it, those of E. nemorosa being dull and patent. 

 From E. Salhhiiryensis it may be distinguished by the ciliate 

 margins of the capsule, the capsule of E. Snlisburgensis being quite 

 glabrous. In the Queen's Drive, Braemar, it occurs with short, 

 white, abundant pubescence, particularly on the under sides of 

 leaves and bracts and calyx, also with aristate toothed bracts 

 = var. Fricsii Sanio (Verb. hot. Ver. Prov. Brandenb. xxxii. S. 123, 

 1891). At Kiuloch Ewe, it occurs with larger and wholly blue 

 flowers, = var. primaria Fries (Nov. Fl. Suec. Mantissa, iii. p. 62).
