but both of them are at most only sparinglj^ branched. Of the 

 remaining two species of Euphrasia bearing yellow flowers, the 

 Andalusian E. WiUkommii Freyn is easily distinguished by its 

 robust, compact habit and broad, deeply cut leaves, and the alpine 

 E. Christ it Favrat by its very large, show}^ flowers. 



The Exmoor plant therefore appears to be an unnamed form, and 

 as there seems no evidence that it is especially connected with either 

 of its apparently nearest allies, E. gracilis, E. nemorosa, and-E". curta^ 

 it can hardly be treated as a variety of one of these, and it becomes 

 necessary to regard it as a new endemic species, intermediate in 

 general features between E. gracilis on the one hand, and jE/. nemorosa 

 and E. curta on the other, but peculiar for its 3^ellow corollas and 

 broad, emarginate capsules. It is proposed to name the plant 

 E. confusa, and it may be diagnosed as follows : —

Caulis suberectus vel adscendens, gracilis, 2-20 cm. (vulgo sub-

 depauperatis simplex), ramis (usque ad 20) flexuosis relative longis

 4-8 dentibus plus minusve acutis obtusiuscula ; floralia (bi'acteae)

In view of the very full description of this jDlant furnished by 

 Mr. Hiern (/. c.) a further diagnosis in English seems superfluous. 

 It may be mentioned, however, that the cauline leaves of well-grown 

 plants are scarcely ovate, though this term may perhaps be used in 

 respect of weak examples such as those originally gathered by 

 Mr. Hiern at Great Cornham. And it is apparently chiefly in 

 luxuriant specimens that the teeth of the floral leaves become dis-
