418 MONOGRAPH OF THE BRITISH SPECIES OF EUPHRASIA. 



DisTRiB. IN Scotland: Aberdeen, "Aberdeen Marshall; (H. 

 Haus.) " ; Wettst. Mon. Caithness, ? grassy headlands, Downreay 

 (1885) ; H. E. Fox. Inverness, Kostven, Moidart (Aug. 2, 1894); 

 S. M. Macvicar (det. Wettst.). Perth, Tumbling Bay ; (J. Britten 

 comm.). Sutherland, abundant from Melvich to Bettyhill (1897). 

 DisTRiB. IN Ireland. I have seen no specimens. 

 The following are localities I give for the var. ylahrescens "Wetts. 

 s="i?. nemorosa ad cvrtam vergens" (Wettst.). 



Surrey, Haslemere (1894) ; K. 8. Marshall (= E. nemorosa s. 1. 

 Wettst.). Pirbright (1881) ; W. H. Beeby. Warwick, Moreton 

 Koad (det. Wettst.). Honington (det. Wettst.). Worcester, Old 

 Stourbridge (1889) ; R. F. Tomulroiv (" or E. nemorosa s. 1." Wetts. 

 det.). 



E. curta is most nearly allied to E. nemorosa. The latter is 

 quite glabrous, whereas E. curta is as a rule remarkably hirsute 

 but never glandular : nevertheless forms occur which are nearly 

 glabrous and which may be distinguished from E. nemorosa by the 

 presence of hairs on the upper side of the leaves and bracts, on 

 the edges of the same and on the calyx. These intermediate forms 

 occur frequently where the areas of the two species meet as in 

 England ; they have been already noticed under the head E. 

 nemorosa ; Prof. Wettstein names them E. curta v. glabre&cens. 



Slender forms occur which may be taken for E. gracilis, but the 

 rugose character of the under surface of the leaves and bracts and 

 the presence of hairs are distinguishing characters. The specimens 

 from Freshwater Downs and Catherine's Cliff referred to this species 

 in the Monograph (Wettst.) are glandular and must be referred to 

 E. occidentalis Wettst. 



Fries first described E. curta in Flora Hall, and in Novit. fi. 

 Suec. ed. 2, p. 198 (1828) as E. officinalis B. montana $■ curta. His 

 short diagnosis and the specimens in Herb. Norm. Fasc. iv. named 

 E. officinalis curta, Fr. Novit. p. 198, certify this. In later years 

 he included other species under the name curta and also under the 

 name parvijiora. Prof. Wettstein believes that hybrids occur be- 

 tween E. curta and E. stricta and E. hrevipila, in localities where 

 these three are found together. 



The plant gathered July 7th 3883, by H. E. Fox on grassy 

 headlands, Downreay, Caithness, which I enter provisionally here, 

 is a very remarkable one. Prof. Wettstein has not ventured an 

 opinion respecting it. The following is a description. Caulis 

 simplex, 3 cm. altus. Folia obtusissima, ovato-rotunda, fere 

 glabra, dentibus paucis obtusis, bractearum superiorum infimis 

 acutis. Spica densa. Corolla parva plerumque purpurea. E. curta 

 is abundant on the moors and pastures from Melvich to Bettyhill ; 

 on the higher ground above the cliffs. At Melvich a much branched 

 form about 6-7 cm high occurs with large flowers 10 mm long, with 

 the upper lip pale lilac, the lower lip white ; it is densely hairy and 

 in fruit the bracts are erect and clasping the fruit. On the short 

 grass in very exposed situations, a very small form with small 

 flowers occurs, and the plant is often quite glabrous.
