ON SOME FORMS OF RHINANTHUS NEW TO 



THE BRITISH FLORA. 



BY G. CI,ARIDGE DRUCE, M.A., F.I,.S. 



A wKH-known Austrian botanist, Dr. J. von Sterneck, has 

 for some time been studying the genus Rhinanthus, for which 

 however he uses the name AlectorolopJms, and I have recently 

 sent him some of my herbarium sheets for his determination. 

 His examination of these shows that three, to which he gives 

 specific rank, are additions to the flora of Great Britain and 

 Ireland. The first of these is one which he identifies as 

 Alectorolophus stenophyllus Schur, Enum. PI. Transs. Index. 

 I collected it at Glengariff, Co. Cork, in 1890, and I have 

 specimens from Lough Owel, Westmeath, collected by W. R. 

 Linton in 1895, and from Bog of Lynn, Mullingar, collected 

 by H. C. Levinge in the same year. Both of these were 

 distributed through the Exchange Club under the name of 

 R. Crista- galli L-, var. fallax Wimm and Grab. Dr. von 

 Sterneck refers both of them to stenophyllus. I have also 

 stenophyllus from East Ross, West Ross, Easterness, Wester- 

 ness, and South Aberdeen, &c, in Scotland, and from 

 Berkshire, so that probably it is widely distributed. It is the 

 Rhinanthus Crista-galli var. angustifolius of my published 

 notes. According to our views of nomenclature it is 

 Rhinanthus stenophyllus Schur, Enum. PL Transs., p. 512. In 

 the "Index Kewensis" it is put as a synonym of Rhinanthus 

 minor Ehrh. Beitr. vi., 144 ; but under the genus Rhinanthus 

 in the same work, Rhinanthus Crista-galli Linn, is said to 

 equal major and minor, and R. minor is kept as a species apart 

 from R. major, while R. Crista-galli is simply put in italics ; 

 yet in treating of the genus Alectorolophus, while A. Crista-galli 

 Bieberstein is said to equal Rhinanthus Crista-galli (put in 

 Roman letters as a distinct species), Alectorolophus minor 

 Dumort. is said to equal R. minor, and A. mi?ior Reichb. is 

 said to equal R. Crista-galli. That is, under the genus 

 Rhinanthus, R. major and R. minor only figure as distinct, and 

 R. Crista-galli sinks to a synonym, yet under Alectorolophus 

 all three are given specific rank.
