ROSA COLLINA 81 
This is a species which has been considerably misunderstood 
on the Continent, as well as in Britain. Crépin regards Jacquin’s 
plant as a gallica x canina (the second parent including of course 
f. dwmetorum). Keller places it in his gallica x dwmetorum 
series, saying thatit isa < elgg aggregate, though some Austrian 
botanists still use the name in a segregate sense. Rouy takes 
much the same view, but "Déséglise looks upon the true Rf. collina 
Jacq. as a definite species and not a hybrid, quoting a species he 
received from the classic locality, which he mie is — =

Jess hairy but not glandular. There is no fruit, but the calyx-tube 
in flower is shortly ovoid or - subglobose, glabrous. Styles hispid,
