MONOGRAPH OF THE BRITISH SPECIES OF EUPHRASIA. 333 



Scheme III. 



K. hirtelUi, s. 1 



E. RostJcoviana, s. 1. 

 E. versicolor Kern. 

 E. Schlagintweitii, s. 1. 



Section I., Eueuphrasia; Subsection I., Semicalcarat^e ; 

 Group II., Grandiflor/e . 



There are twelve species in this group. The species are, E. 

 Hhnalai/ico, E. Schlariintweilii, E. Roskoviana, E. campestris, E. mon- 

 tana, E. paucifoUa, E. petiolaris, E. Kerncri, E. incta, E. versicolor, 

 E. alpma, E. Christii. Their distributiou betokens a connection 

 with the E. pectinata series, and so does the zenogarnic character of 

 the flowers. The areas they occupy are to be found in the southern 

 portions of the area occupied by that series. Morphologically seven 

 of the species are distinguished by being furnished with glandular 

 hair.s, and of these we have in the British Isles only one repre- 

 sentative, viz. E. Eostlwviana.--'- 



It is interesting to find that E.. paucifoJia has a similar relation 

 to E. Schlafiintweitii or E. Hivialaijica as E. montana has to E. Host- 

 koviana. E. Eostkovinna occupies a Mid-European area ; the other 

 three species are found only in the Himalaya. The morphological 

 character of all these betokens near relationship; possibly they 

 have sprang from an ancestor which formerly occupied a wide 

 range over Eastern Asia and South-west Europe. E. petiohnis 

 is a mountain species occupying an area between that of E. Uost- 

 knviana and the Himalayan species, and may possibly have a similar 

 origin. 7'.'. conipcstris doubtless sprung from /'.'. liostkoriana. 



Of the eglandular species, which arc five in number, we have 

 also only one representative, viz. E. Kerncri. As far as our present 

 knowledge goes, these five species only occur in South-west Europe. 



* Unless E. campestris Jord. can be reckoned as indigenous. See the remarks 

 which follow the descriptions of E. liostkoviana and E. camjtestris.
