MONOGRAPH OF THE BRITISH SPECIES OF EUPHRASIA. -469 



July 30, 1884, which resembles it. It is the E. officinalis, a. Piost- 

 koviana, f. tenuia mihi of the London Catalogue, ed. 9. It is 7-10 cm 

 high. The flowers are moderately large, the calyx and bracts with 

 very short glandular and eglandular hairs, the style as in E. Rost- 

 koviana, the leaves and bracts have a cuneate base. Prof. Wettstein 

 having only seen specimens in an early stage entered this plant in 

 his Monograph as E. brevipila (p. 12, Wettst. Mon.), but having 

 sent him more advanced specimens he now sees they cannot be 

 referred to that species. He writes " Eine Pflanze, die mir nicht 

 klar ist," but says that if it is within the area of E. campestris it 

 would in fact be E. campestris Jord. A hybrid between E. Rost- 

 koviana and E. nemorosa which I found in the same neighbourhood 

 in company with its parents, bearing the characters of them both, 

 is a very different plant. 



E. campestris differs from E. Rostkoviana by its humbler growth, 

 its branches usually springing higher on the main stem, by its 

 narrower leaves and bracts furnished with much more shortly- 

 stalked glands. Prof. Wettstein hesitates to give a definite opinion 

 about it, but remarks that it comes very near E. Rostkoviana. 

 Taking into consideration its wide distribution throughout a con- 

 siderable portion of the Rhoue watershed, the constancy of its 

 characters, and its acceptance as distinct from E. Rostkoviana by 

 those botanists who have seen the living plant (Jordan, Muret, 

 Renter), Prof. Wettstein also accepts the distinction, looking upon 

 it as a species derived from E. Rostkoviana at a comparatively 

 recent date, and leaving it to further observation to determine 

 whether the separation is warrantable.
