separaLle. It is also probable that in the British form the lower 

 leaves are relativel}'^ narrower. 



The occurrence of M. hirtella in North Wales might not mi- 

 reasonably be expected from its Continental distribution. It is found 

 in Central and Northern Spain, in the Pyrenees, in the French, 

 Italian, and South-Western Swiss Alps; and eastwards, it is said to 

 extend from the T^'rol through the Balkan Peninsula, Transcaucasia 

 and Siberia to Chinese Mongolia. In France it reaches the depart- 

 ment of Haute-Loire and the mountains of Auvergne. 



In connection with E. hirtella it seems desirable to allude to 

 IE. fennica Kihlman, included as British in Mr. Bucknall's British 

 J^uphrasicB (p. 27). Of this plant there is an authentic sheet in 

 Herb. Kew from Kihlman himself (PL Finlandise Exsicc. no. 354, 

 as E. hirtella Jord. var. fennica Lind. fil. (£!. fennica Kihl.)), and 

 I possess other good Finnish material. It is a form somewhat inter- 

 mediate between U. hirtella, to a variety of which it is apparently 

 reduced by Kihlman, and E. Bosthoviana, to which it has been 

 likened by Wettstein. Of the former it possesses the strict, erect 

 habit, but it is taller and more slender, with long lower internodes 

 and a tendency to branch about the middle of the stem. Its lowest 

 leaves are easily caducous as in E. hirtella, but its corolla is much 

 Lii'ger, 7-8 mm. long, with the lower lip distinctly longer than the 

 upper one and with broader segments, and hence approaching the 

 iiower of E. Rostkoviana. On the whole, however, there seems good 

 ground for placing it under E. hirtella, to the type of which it seems 

 nearer than some Asiatic examples that have been so named. I have 

 had no opportunity of seeing Mr. Druce's original Exmoor specimen 

 determined by Dr. Lindman, but those collected in that district io 

 1917 and 1918 by Mr. Barton and the Pev. E. S. Marshall do not 

 a])pear to me to be identical with the Finnish form but rather modifi- 

 cations of E. Mosthoviana. 



E. hirtella may be described as follows : —

 Haller. iv. 120 (1854-6) ; Wettstein, Mon. der Gattung Euphrasia, 

 175 (1896) ; E. tatarica race E. hirtella Rouy, Fl. France, xi. 149 

 (1909).

Stem strict and erect, of variable size but usually robust, 3-25 cm. 

 high, simple or occasionally with one or few erect branches towards 

 the base, more or less purplish, pilose (especially above) with long, 

 whitish, flexuous and partly glandular hairs. Leaves svibopposite, 

 dull green, up to 8 mm. long or larger in vigorous plants, clothed 

 M'ith whitish bristles and abundant long, flexuous, unequal glandular 

 hairs ; the lowest leaves obovate, or in the British form narrower and 

 cuneate below, obtuse, with few obtuse teeth ; upper cauline leaves 

 ovate or broadly ovate, obtuse or subacute, with 3-6 more or less 

 acute teeth on each side ; floral leaves broadly ovate or triangular- 

 orbicular, acute, with 4-8 acute or acuminate but not awned teeth on 

 each side ; nerves prominent below when dry ; lower leaves often
