RYDBERG: NOTES ON ROSACEAE 75 
thick and orange; sepals lanceolate, caudate-attenuate, about 1.5 
cm. long, glabrous or nearly so on the back, tomentose on the 
margins and within, in fruit erect and persistent; styles distinct, 
persistent, not exserted; achenes inserted both in the bottom and 
on the inside of the hypanthium. 
This species is related to R. Woodsii, but differs in the yellowish 
green leaflets, sharply serrate with teeth directed forward, the 
orange fruit and usually many-flowered corymbs. The following 
belong here: 
Urau: Allen Cafion, 1911, Rydberg & Garrett 9302 (type, in 
the herbarium of the New York Botanical Garden); Logan, Miss 
Mulford 189. 
Ipano: Castford, 1912, Nelson & Macbride 1749; Rock Creek, 
1911, Macbride 1375; King Hill, 1912, Nelson & Macbride 1109. 
Nevapa: Franktown, Kennedy 1935; Kings Cafion, Baker 
1221. ;

15. ROSA MOHAVENSIS Parish, Bull. So. Calif. Acad. 1: 87. 1902 
This was originally described as R. californica glabrata Parish. 
Parish overlooked the fact that there was an older R. californica 
glabrata Crépin. The present species is not related to R. californica 
but to R. Woodsii, from which it differs in the shining, elliptic 
instead of obovate, leaflets.

16. ROSA MYRIANTHA Carr. Rev. Hort. 1865: 448. 1865 
This species, not uncommon in California, has generally been 
overlooked. Crépin, apparently not knowing it very well, admitted 
it asa variety glabra of R. californica, notwithstanding the fact 
that it has straight prickles. Regel described it under the name R. 
californica. From his treatment it is not evident that he even 
knew of the existence of R. californica Cham. & Schlecht., but itis 
evident that he was not familiar with it. The following specimens 
belong to R. myriantha: 
Catirornta: Eel River, Heller 6044; Red Reef Cajfion,
