SOME REMARKS ON EUPHRASIA AND RHINANTHUS 177 



land it grows in two different habitats ; being found both 

 near sea-level and on mountains, from about 2000 to 3 700 

 feet (I collected it on Ben Lawers so long ago as 1887). 

 With characteristic E. scottica it can hardly be confused, either 

 fresh or dried; being, as Wettstein says (" Mon." p. 140), 

 nearest to E. latifolia ; from which it is distinguishable by 

 its usually smaller size, fewer branches, much longer capsules, 

 and by being far less hairy. It also approaches some coast- 

 forms of E, curta in general appearance. 



It is, however, probable that two distinct Scottish forms 

 have been referred by Wettstein to E. foiUaeitsis. Early 

 in 1904 Mr. Townsend sent me specimens and detailed 

 drawings of an Eyebright from Norway, which he intended 

 to publish and figure as E. minutiflora, n. sp. These at once 

 struck me as being practically identical with plants gathered 

 abundantly in 1897 by Mr. Shoolbred and myself on heathy 

 banks near ]\Ielvich, W. Sutherland, which had always seemed 

 to me considerably different from the other specimens named 

 E. fotdaensis by Wettstein ; and, on receiving my three 

 herbarium sheets of this, Mr. Townsend agreed that they 

 were his proposed species. Soon afterwards his health began 

 to fail ; and both his drawings and types and my own speci- 

 mens have unaccountably disappeared. Among his botanical 

 correspondence subsequently sent to me, I found my letters 

 dealing with this subject. The main distinction from E. 

 foiilaensis seems to lie in the flowers, which are somewhat 

 smaller, with the tube nearly or quite included in the calyx, 

 and of a beautiful violet-blue, as in E. Vigursii ; I think 

 that it is also a taller, more branched, and somewhat narrower- 

 leaved plant than the ordinary coast-form of E. foulaensis^ but 

 have no precise recollection and no further examples. It is 

 sure to occur in other localities in northern Scotland. 



Rhinanthiis stenophylbis is considered by Mr. Beeby to 

 be an " autumnal " variety of R. minor. In England it does, 

 upon the whole, bloom some weeks later ; yet I have speci- 

 mens from Warminster, S. Wilts (so named by Dr. von 

 Sterneck), gathered in flower and young fruit on loth June 

 1903 ; and in N. Scotland (W. Sutherland, E. Ross), it 

 begins to blossom quite early in July — little, if at all, later 

 than R. minor.
