RypBERG: NOTES ON ROSACEAE 71 
called it R. californica Petersiana.* Crépin changed the varietal 
name to glandulosa.t_ He also gave R. Aschersoniana Crépin as a 
synonym. Rosa Aldersonii was described from a specimen, not 
quite of the usual form, having small, more rounded leaflets, short 
prickles and congested inflorescence. Rosa Breweri Greene} is, 
in my opinion, only a stunted and somewhat abnormal form of 
this species, with densely glandular pedicels and more hairy 
leaves. R. Aldersonii is, besides, very variable, usually with a 
subglobose hypanthium, with a distinct neck, but sometimes with 
a somewhat ellipsoid hypanthium. It also varies in having larger 
or smaller leaflets and with numerous or few flowers. Sometimes 
the styles are more or less exserted. It is fully as common as the 
preceding throughout California. 
7. Rosa Greenei Rydberg, sp. nov. 
Stem rather slender, 1 m. orso high, purplish, glabrous, armed 
with curved infrastipular prickles, which are more or less flattened, 
3-6 mm. long; leaves five- to seven-foliolate; stipules narrow, I-1.5 
cm. long, densely glandular-puberulent; petiole and rachis glandu- 
lar-puberulent and somewhat prickly; leaflets elliptic, acute at both 
ends, 2-4 cm. long, glandular-double-toothed, puberulent above, 
glandular-puberulent and _ slightly pilose beneath; inflorescence 
corymbiform or paniculate; pedicels 1-2 cm. long, glandular- 
puberulent; hypanthium elongate-ellipsoid, with a distinct neck, 
in fruit 2 cm. long and 1 cm. in diameter; sepals lanceolate, caudate- 
acuminate, about 2 cm. long, glandular-hispid on the back, to- 
mentose within, in fruit persistent and erect; petals about 15 mm. 
long, rose-colored; styles distinct, persistent, not exserted. 
This is related to R. Aldersonii, but differs in the narrower 
leaflets and the decidedly ellipsoid hypanthium, with a Jong neck.

8. Rosa brachycarpa Rydberg, sp. nov.
