adopted, or that he has been mistaken in associating plants so 
dissimilar. I cannot, consistent with my group definitions, accept 
the Coquetdale plant as Ff. canescens. 
Mr. Baker’s No. 20, from Thirsk, at the National Herbarium, 
has rather small roundish oval leaflets, which are quite biserrate. 
The petioles are pubescent and somewhat glandular. The sepals 
have broad, strongly glandular-dentate pinne, but the flowers 
being only in bud, no characteristics can be derived from fruit 
and styles. A sheet bearing the same number at Kew has much 
larger leaflets, and is in a more advanced state, showing that the 
styles are somewhat densely hairy, but not in a broad woolly head 
like those of R. coriifolia. A specimen cultivated at Kew by Mr. 
Baker has quite thinly hispid styles, and very small but broadly 
ovoid fruit. 
It seems to be a frequent plant on the Continent, and the very 
broad glandular-dentate sepal pinne of the type are well repre- 
sented in most of Déséglise’s specimens. This characteristic is 
the only one I can see which justifies Crépin’s opinion that it 
tella. 
No opinion as to which of my groups R. canescens should fall 
into can be deduced from Déséglise’s Catalogue Ratsonné, because 
R. dumetorum and R. coritfolia, from both of which he at once 
separates R. canescens by its biserrate leaflets. Boullu, how- 
ever, said that Déséglise told him that he considered it to be 
synonymous with FR. hemitricha Rip., a ini i 
ullu did not concur, pointing out that the type of that 
species has globose fruit, but that he had named a variety of it 
Beugesiaca, which has ovoid fruit, and which he considers to be 
the same as R. canescens Baker. -
