Eedeistins July 6th, 1904.—S. H. Bicxnam. This may be 
rightly named, but I am not clear as to what Baker means by his 
arvatica. He says ‘‘non Puget,” but Déséglise, in his Cat. Raisonné, 
p. 269 (1877), makes Baker's and Puget’s plants synonymous, and 
classifies them in his sub-section Pseudo-rubiginosa, which have 
glands all over the under surface of the leaflets, such as this plant 
as not.

peduncles are the same, but R. cesia should have glandular 
peduncles and Sire glandular on the back. Perhaps both plants 
should go under R. canescens Baker = R. canina var. incana Baker,

Ba st. LI see no evidence of arvensis. The shape, size, and spacing 
of the leaflets, and their being more or less hairy beneath, also the 
pinnate sepals, short thick style column, shape of fruit, and—as far 
as I can judge—colour of petals, all point to systyla.— A. H 
WoLLe Des, This rose has much of the appearance of a R. systyla 
form, and the specimens show little sign of any divergence. But 
the reported habit of the plant, and its tendency to sterility, coupled 
with the rather long peduncles, are fair evidence o 
R. arvensis parentage, and the subglabrous rene fall in 
theory. AR. arvensis often has ovoid fruit.—E. F. L.
