Stems tall, arching ; prickles uniform, robust, hooked, often in infrastipular 
pairs. Leaflets 7-9, oblong, obtuse, green, middle-sized, simply openly serrated, 
glabrous on the upper surface, often pubescent beneath ; petioles pubescent and 
aciculate ; stipules broad, adnate, gland-edged, with small, ovate, free tips. Flowers 
many, arranged in a corymbose panicle ; bracts oblong-lanceolate, gland-edged ; 
pedicels short, naked. Calyx-tube small, globose, naked ; lobes ovate-acuminate, 
i-f in. long, naked on the back. Petals small, pink. Styles free, villous. Fruit 
globose, bright red, naked ; sepals deciduous. 
Rosa californica is distinguished from the other American Cinna- 
momeae by its robust prickles, almost as hooked as in Rosa canina L., 
and by its small pale pink flowers produced in clusters, often as many 
as thirty or forty in a panicle. It varies much in habit. As we know 
it in England, it is distinguished by its tall growth, the bushes frequently 
attaining a height of five or six feet, but from the description of this 
Rose in its native habitat it would seem to vary r in stature from quite 
dwarf bushes. It is common in California, ascending to 6,000 feet 
above sea-level in the Sierra Nevada, and it extends to British Columbia, 
Oregon, Nevada and Washington. 
Rosa californica is extremely polymorphous. When Crepin first 
examined the specimens sent him, he was inclined to make varieties of
