74 RYDBERG: NOTES ON ROSACEAE 
County, October 16, 1900, Dudley 3388 (in the Dudley her- 
barium, Leland Stanford University). 
13. ROSA RIVALIS Eastw. Bull. Torrey Club 32: 198. 1905 
This species is related to R. Woodsii and R. pisocarpa, but its 
leaflets are much larger, broader and thinner, broadly oval, 
sometimes almost orbicular and perfectly glabrous beneath. 
They resemble somewhat those of R. myriantha, which, however, 
has pubescent leaves. I have not seen the type of this species 
but showed Kellogg & Harford’s No. 226 to Miss Eastwood, and 
she said that she regarded the same as typical R. rivalis. In the 
Missouri Botanical Garden herbarium, the locality of this number 
is given as San Francisco. This is probably wrong. In the her- 
barium of the New York Botanical Garden, Kellogg’s field label 
is present, which reads: ‘‘Rosa. Long Valley, June 11, 1869, red, 
7 or 8 feet high—along shady rivulet—Kellogg.” According to 
Miss Eastwood, Long Valley is not very far from the type locality 
of R. rivalis. A form with leaves somewhat pubescent beneath 
and somewhat glandular petioles was collected by Mrs. Austin (No. 
400) at Mill Creek, California. The following belong to R. rivalis: 
CaLiFoRNIA: Long’ Valley, Kellogg & Harford 226; Placer 
County, 1893, Mrs. Hardy (on this sheet Crépin has written: 
“N’est pas le R. spithamaea Wats., ou le californica, etc.’’). 
OREGON: Cold Spring, Crook County, 1898, Coville & A pplegate 
rit. 
14. Rosa chrysocarpa Rydberg, sp. nov. 
Stem tall, 1-3 m. high, terete, at first light yellowish green, 
later grayish brown, armed with straight prickles, somewhat re- 
trorse, terete, 3-7 mm. long, usually more or less flattened at the 
very base, some of them infrastipular, others scattered, of various 
lengths; young shoots copiously armed with bristle-like prickles; 
floral branches 1-2 dm. long, armed with mostly infrastipular 
prickles; stipules adnate, glabrous, 1-2 cm. long, the lower narrow, 
the upper dilated, glandular-dentate or ciliate on the margins; 
petiole and rachis glabrous, sometimes with a few prickles; leaflets 
five to seven, elliptic or oval, thin, glabrous on both sides, yellowish 
green, coarsely serrate throughout, petioluled, 1-4 cm. long; flowers 
corymbose, leafy-bracted; pedicels 1-2 cm. long, glabrous; hypan- 
thium globose, glabrous, at first light-green, in fruit about 1 cm.
