72 Rydberg: Notes on Rosaceae 



glandular-ciliate on the margins and glandular-puberulent on the 

 back; petioles and rachis glandular-puberulent and slightly 

 prickly; leaflets elliptic or narrowly oval, mostly acute at both 

 ends, rather evenly serrate, with broad, occasionally double, and 

 gland-tipped teeth, conspicuously glandular-puberulent and 

 slightly pilose beneath, 2-4 cm. long; inflorescence rather many- 

 flowered, corymbiform; pedicels about i cm. long, glabrous or 

 nearly so; hypanthium depressed-globose, without a neck; sepals 

 ovate, caudate-acuminate, about 1.5 cm. long, glabrous on the 

 back, villous on the margins and tomentose within; in fruit erect 

 and persistent; petals about 15 mm. long; styles distinct, persistent, 

 decidedly exserted. 



This species is also related to R. Alder sonii, but differs from 

 all the other relatives of R. californica in the hypanthium lacking 

 the neck, and in the decidedly exserted styles. 



California: Temescal Canon, near Elsinore, May 23, 1892, 

 McClatchie (type, in the herbarium of the New York Botanical 

 Garden). 



9. Rosa pinetorum Heller, Muhlenbergia i : 53. 1904 



This species has been collected only in the neighborhood of the 

 type station, that is around Monterey Bay. The following speci- 

 mens have been seen. 



California: Pacific Grove, Heller 6817; 1907, Patterson & 

 Wiltz; 1908, L. E. Cox; Point Pinos, Heller 8413; Monterey, Parry. 



10. Rosa calavera Greene, Leaflets 2: 257. 1912 



This was included in the R. gymnocarpa group by Dr. Greene, 

 perhaps on account of the shape of the leaflets and the small 

 flowers, but the sepals and style are persistent and it is more nearly 

 related to R. pinetorum, differing in the small flowers and the leaflets 

 which are pale beneath. While R. pinetorum is confined to the 

 coast, this species belongs to the Sierra Nevada. 



California: Calveras Big Tree Grove, E. L. Greene; Tulare 

 County, Dudley, at the following localities: Second Dry Meadow 

 Creek, Kern River, 1895; Board Camp, 1902; Keweath River
