1953. Rliinant lius Perrieri, Chabert, in " Bull, de 1'Herb. 

 Boiss." 1899 (Or. g\ p. 512. Dr. von Sterneck (" Mon. der 

 Gattung Alectorolophus," p. 108, 1901), while quoting 

 in synonymy the above name for his ntsticulus, says : '' Die 

 Exemplare von Modane beschreib Chabert, a.a. O, unter 

 dem Namen R/iin. Perrien und stiitze die Begriindung der 

 neuen Art einzig und allein auf das Anwachsen der Corolla 

 in Laufe der Anthese. Die iibrigen die neue Sippe character- 

 isierenden Merkmale (der kurze Stengel, die ' Calyces aeno- 

 chroi,' die mangelende Verzweigung) deuten direct ihre 

 Stellung in der monticolen Formenreihe, somit ihre Identitut 

 mit A. msticulus an." 



Therefore, as he also alludes to R. Perrieri under 

 A. minor, I followed Sterneck in choosing rusticulns as the 

 specific name (for which we are also indebted to Chabert), 

 since a species, founded primarily on a character possessed 

 only in common with other species of the genus as is Perrieri, 



cannot be cited.

 By WILLIAM H. BEEBY, F.L.S. 



LAST year attention was devoted to the central portion of 

 the main isle, a part which I had been unable to visit before. 

 Although there is a good deal of limestone in this district

and I had anticipated that the flora might exhibit some 

 interesting features, the country did not prove very produc- 

 tive. Three long ranges of hills, the Easter Kame, Mid 

 Kame, and Wester Kame, run parallel for miles. Their 

 average height may be called 400-500 feet, with many 

 higher points, the highest, Scallafield, in the Wester Kame, 

 reaching 921 feet. For a long distance the ridges are but 

 a quarter of a mile apart, so the valleys are narrow. A 

 limestone dyke runs along the whole length of the Weisdale 

 valley, but it is mostly covered with surface soil which
