SPECIES DUBIA. 135 
Described by Pursh from specimens in Lyons’s her- 
barium. 
This is another plant evidently very like R. carolina, 
although perhaps sufficiently distinct on account of the 
scattered prickles. But when Pursh saw Mr. Sabine’s 
Roses at N. Mimms, he pointed out a plant growing 
there as his R. Lyonit. This I unfortunately have not 
seen with leaves on; but in its leafless state it differs 
in no respect from R. carolina except in having smooth 
fruit and some of the prickles falcate.

This species is related to R. sempervirens, which has 
white flowers; leaves simply serrated; petioles smooth; 
the divisions of the calyx entire. The present plant has 
a stem 4 to 6 feet high, covered with hooked prickles; 
the branches hispid, reddish, panicled, with three flowers 
or more; petioles very bristly and glandular; leaflets 
5-3, roundish oval, somewhat obtuse, green, shining 
above, paler beneath; the denticulations glandular and 
toothed; stipules ciliated, glandular; bractez amplexi- 
caul, reddish, lanceolate, pointed, glandular beneath, 
two often opposite with a third larger and lower down; 
peduncles reddish, hispid, glandular; divisions of the 
calyx pinnatifid; the flowers large, purple; petals oval, 
rounded, slightly scented; tube oval, hispid; styles 
distinct, twice as short as the stamens; fruit oval, globu- 
lar. Grows in hedges at the foot of Mount Baldo. 
Pollin. ex Poiret. 
A mere variety of rubiginosa?  Pollin probably 
means to compare it with the R. sempervirens of some 
German botanists, not. of Linnzus.
