ADDENDA 



Since the first portion of the article was written and printed, the following additional 

 particulars have been collected. 



The census of species, calculated on the scale of the ninth edition of the London Catalogue, 

 must be slightly increased, so as to include eighteen extra species, namely, four belonging to 

 the order Compositae, two to each of the two orders, Euphorbiaceae and Liliaceae, and one to 

 each of the ten orders, Cruciferae, Leguminosae, Onagrarieae, Umbelliferae, Rubiaceae, Eri- 

 caceae, Scrophularineae, Labiatae, Salicineae, and Naiadaceae. Thus the total number of 

 recognised Devon species of flowering plants becomes 1,156, of which number 882 apply to 

 dicotyledons and 274 to monocotyledons ; the proportion of the numbers of these two groups 

 is approximately as 3*22 to l ; and the percentage of the number of Devon flowering plants, 

 compared with that of the British Isles, is rather greater than 62' i. 



The new literature dealing with Devon plants consists mainly of papers contributed to 

 the Journal of Botany. The lists of the more remarkable and interesting plants may be 

 extended as follows : —
