NOTES OX EKTTISII EUPHRASIAS 5 



SO marked a feature of Host's species. The specimens originally 

 determined by Wettstein and cited ])y Townsend are mostly quite 

 small examples, of slender habit and Ijranched towards the base, with 

 rather large white flowers, which, if not forms of U. nemorosa, are 

 probably connected with the British E. Kerneri. The ])lants to which 

 Townsend in his last 3^ears applied Host's name are most diverse in 

 appearance, but are mainly white-flowered forms approaching j&. ne- 

 morosa. My Bossington plant of 1910 is perhaps as near to jE'. sfricta 

 as any English foriu that I have seen, but its branching is too basal 

 and too profuse, and it bears white flowers. This likewise is probably 

 connected with a polymorphic E. nemorosa. Mr. Barton's Welsh 

 plants, though robust, are not stiffly erect, but somewhat decumbent 

 below, and sometimes considerably branched near the base. Their 

 cauline leaves lack the spreading aristate teeth of E. sfricta ; and 

 their flowers are white with the cal3^x becoming distinctly inflated 

 and accrescent, enclosing a relatively large capsule. These plants 

 seem to be a coarse, luxuriant form of E. nemorosa. Forms of 

 E. horealis also have been confused with E. strict a., but these differ 

 widely in their less strict habit, large leaves with broad teeth, strongly 

 accrescent calyx, white corollas and large capsules. 



E. stricta is a typical and Avidely distributed E^^ebright of Central 

 Europe, extending, according to Wettstein, from the Pyrenees to 

 Russia and from ^orth Italy to Denmark and Sweden. In France 

 it grows chiefly in the south-east, but it is reported to reach Normandy 

 and Brittany, so that its occiu'rence in the south of England would 

 not be surprising. But, as it is one of the few readily determinable 

 species, it should be possible to prove beyond doubt the identity of 

 British specimens, and I do not think it can be admitted on present 

 evidence as a native of Great Britain. Bespecting the occurrence of 

 E. stricta in Ireland I cannot express a definite opinion, having seen 

 only fragmentary specimens, but it is possible that County Galway 

 is an outlier of the range of this species as of E. salishurgensis. 



Since writing this paper I have seen the note on E. confiisa by 

 Messrs. Pearsall and Lumb in the Botanical Exchange Club lleport 

 for 1920 (p. 2-11), in which the writers contend that E. minima (of 

 which they do not appear to have read Wettstein 's diagnosis) may be 

 extended to include E. confiisa. The modern species of Euplirasia 

 are too finely cut to admit of much extension, and I cannot see that 

 any essential feature of E. minima is mentioned which is peculiar to 

 that plant and to ^. conAisa. I think that on the reasoning adopted 

 E. confiisa might be much more easily included with E. nemorosa, 

 and almost equally well with any other British species. The British 

 plants that may perhaps be united with E. minima are in my opinion 

 some of those that have been referred to E. scotica and E. foiiJaensis.
