48 RYDBERG: NOTES ON ROSACEAE 
understood and no specimens need to be cited. The only syn- 
onyms the author has found, are: R. lucida Lawrence, and R. 
Macartnea Dum. Cours. The former is a hyponym and a hom- 
onym. The latter has often been given as a synonym of R. 
laevigata, but erroneously so, for it is easily seen from Dumortier’s 
description that it belongs to R. bracteata. 
III. GALLICAE 
One species. 5. R. gallica. 
5. Rosa GALLICA L. 
Cultivated in many forms and occasionally escaped. Some 
of these escaped specimens may belong to the pure-blooded 
R. gallica, but others are plainly referable to R. centifolia. Whether 
or not the latter is a distinct species is a question which I have had 
neither the time nor the inclination to settle. The following 
specimens, belonging to R. gallica or closely related species, have 
been recorded within the area. 
NEw York: New Baltimore, NV. Taylor. 
WISCONSIN: Stennett. 
IV. CANINAE 
Leaflets glandular-pruinose ae distinctly double-ser- 
rate with gland-tipped tee 
Leaflets suborbicular or cons oval, mostly rounded at 
the apex; hypanthium in fruit obovoid or broadly ellip- 
soid, abruptly contracted at the apex; sepals tardily 
ets ] ; rei t - 6. R. rubiginosa. 
Leaflets ovate or oval, acute or short-acuminate; hypan- 
thium in fruit narrowly elliptic, tapering at both ends; 
_ sepals rather early deciduous; styles glabrous or nearly 
so. 7. R. micrantha. 
Leaflets not glandular beneath, except sometimes on the 
midrib; teeth only occasionally double. 
Leaves pubescent, at least beneath, and on the rachis. 8. R. dumetorum. 
Leaves glabrous on both sides, shining above. 9. R. canina. 
6. ROSA RUBIGINOSA L. 
The Sweetbrier is often cultivated and has become thoroughly 
naturalized in many places. It is very variable in cultivation 
and the naturalized specimens show also such variation. All 
specimens labeled R. rubiginosa do not, however, belong to “ 
species. At least one-fourth of them belong to the next.
