though seldom so broad asin the Canine. They are usually shorter 
than but sometimes as long as the peduncles. The styles are 
quite glabrous, and usually combined into a column, but are very 
often free, and though typically long sometimes scarcely exceed 
the disc. In the Hu-canine coalescence and considerable pro- 
trusion of styles are not spac iagses and such specimens are often 
referred to the Stylos@, in some cases, I have thought, correctly, 
ut in Ff. systyla Bast., if not slices in all the segregates, the

It is generally distributed in the South of England, from 
Essex, Kent, and Middlesex to Gloucester and Corn wall, and I

common, though often collected on account of its t OOUEDIN ONE 
but I can only speak from my own experien A specimen 
labelled R. systyla var. Desvauxii Baker from Racket Sussex, 
belongs here, and not to R. stylosa Desv., of which var. Desvaucit 
is a synonym.

‘Leaflets ovate-lanceolate. Fruit spherical.” 
I include this because it was founded on a British plant 
gathered in Ireland, of which I have not seen a specimen, but 
Crépin (Journ. Bot. 1896, p . 179) says the specimen in Lindley’s 
herbarium is a Misroiahs 4 so it is doubtful whether the name can 
stand. The same name has been adopted by De Pronville, a 
French author, and there are several specimens in herb. Déséglise 
which appear to be characterized rather by their spherical fruit 
than by any peculiarity in the shape of the leaflets, Dough some 
of the specimens have them narrow-lanceolate. These forms 
would seem to fall under R. erratica Rip. Such forms could, = 
mens so named, those which have the leaflets have not always 
the fruit.
