acuminate, but not necessarily narrower than in R. arvensis. The

Suppl. to Eng. Bot. ed. iii. p. 159, that Déséglise has referred 
here specimens from Malvern, Worcester ; Knighton Heath, 
Devon; and Chetnole, Dorset. I suspect that much of our 
fi. dibracteata belongs here.

‘‘ Leaves with compound teeth (2-3-dentate).”

“ Peduncles smooth. Petioles not or very rarely glandular.” 
The above description appears to be the only one published, 
know, has the petioles pubescent and its peduncles not qui 
eglandular, so it is not quite typical. .
