ON THE NECESSITY FOR A NEW MONOGRAPH OF ROSES 39 



ON THE NECESSITY FOR A NEW MONOGRAPH 

 OF THE ROSES OF THE BRITISH ISLANDS. 



By FRANCOIS CREPIN. 



(Translated from the French in " Bull. Soc. Belg. Bot.," xxxi. 



part. i. pp. 14-25.) 



THE Roses of the British Islands have been made the 

 subject of two monographs. The first, by Woods, dates 

 from 1813 ; the second is that published by Mr. J. G. Baker, 

 in 1870, in the "Journal of the Linnean Society." 



Since the publication of this latter monograph the con- 

 tinuous study of the species and varieties of the genus Rosa 

 has perfected the knowledge of the very numerous forms of 

 this generic group and of their synonyms, and has thus 

 rendered necessary the revision of the old works. It is to 

 be desired that some young English botanist would take up 

 the work of these predecessors, and prepare a new mono- 

 graph of the English Roses, brought into harmony with the 

 present state of science. 



Except a certain number of varieties or local forms, the 

 English Roses are the same as those of the neighbouring 

 countries, and one can now prepare the list of specific types 

 inhabiting England, Scotland, and Ireland. This list will 

 include : 



Sect. I. Synstylse. Sect. III. Caninse. 



R. arvensis, Huds. Sub-sect. EUCANIN^E. 

 Sect. II. Stylosse. R. canina, L. 



R. stylosa, Desv. R. obtusifolia, Desv. (in- 



R. glauca, Vill. (including eluding R. tomentella, 



R. coriifolia, Fr.) Lem.) 



Sub-sect. RUBIGINOS^E. Sub-sect. TOMENTOS^;. 

 R. rubiginosa, L. R. tomentosa, Sm. 



R. micrantha, Sm. Sub-sect. VILLOS^E. 

 R. septum, Thuill. R- mollis, Sm. 



? R. graveolens, Gren. Sect. IV. Pimpinellifolise. 



R. pimptnellifolta, L. 



We do not include in this list R. rubella, Sm., which can be 

 nothing but an accidental variation of R. pimpinellifolia, and 

 not at all R. pimpinellifolia x alpina, or R. hibernica, Sm.,
