164 NOTES ON A NEW SUBSPECIES OF EUPHRASIA OFFICINALIS. 



" When, as I have already remarked is sometimes the case, E. 

 capitulata is eglaudular, it may at first sight be taken for broad- 

 leaved purple- flowered E. minima, but the long jointed and not ad- 

 pressed hairs on the stem, and the horizontal direction of the 

 flowers of E. capitulata will distinguish it. The presence of glan- 

 dular hairs is not constant, apparently, in any subspecies of Eu- 

 phrasia. Though glandular hairs are characteristic of E. Rostko- 

 viana, Hayne, E. hirtella Jord., and E. capitulata niihi, yet eglan- 

 dular forms of these three subspecies do occur. There are, how- 

 ever, other peculiarities in the pubescence which appear more con- 

 stant ; such are the long jointed hairs found in all the three last- 

 named plants, though even these are sometimes absent as in the 

 high alpine forms of capitulata and of Rostkoviana, the latter being 

 named by Gremli, Euphrasia anadena (= Euphrasia Rostkoviana /3. 

 alpestris Gremli, olim) in his ' Neue Beitrage zur Flora der Schweiz,' 

 Heft 4, Aarau, 1887. 



" Sept. 10. To-day I walked from the Grosse Scheideck to the 

 Faulhorn. The road, at first, is nearly level for a considerable 

 distance, but afterwards ascends within sight of the Hotel of the 

 Grosse Scheideck, and about three quarters of an hour's walk from 

 the latter. On the wet alpine pastures, soon after commencing to 

 ascend, I found E. capitulata, small forms of it, about lj inches 

 high ; further on the plant occurred abundantly, and I noticed it all 

 the way onwards till within half an hour's walk of the Faulhorn 

 Hotel. I was thus able to gather abundant specimens of this 

 interesting plant. It has, here, the dark-green foliage which I 

 noticed as so characteristic when I first found it at Miirren. E. 

 minima Schleich., occurs here abundantly also, and in company 

 with E. capitulata. On the slopes, where the road passes close to a 

 fence, about one hour's walk from the Scheideck, and on the south 

 side of the fence, I found large plants of E. hirtella Jord., with its 

 characteristic pale green foliage and pale flowers. E. capitulata 

 evidently prefers the wetter spots and E. hirtella the drier ground. 

 The bracts of E. hirtella are broader than those of E. capitulata 

 and more or less cordate at the base ; the tips of the leaves and 

 bracts have not the same tendency to curve downwards as in E. 

 capitulata. The upper bracts of the latter have a more or less 

 cuneate base." 



I have drawn up the following description of E. capitulata : — 

 Euphrasia capitulata mini, nova subspecies = E. minima var. 

 intermedia Towns. (Journ. of Bot. 1884, p. 167).
