Stems tall, arching ; prickles uniform, robust, hooked, often in infrastipular

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,

Rosa californica is distinguished from the other American Cinna- 
mo 7 neae 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 m 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 m its native habitat it would seem to vary 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 ( 'oliimbia, 
(Oregon, Nevada and \\ ashmgton. 
Rosa californica is extremel)^ polymorphous. When ( repin lirst 
examined the specimens sent him, he was inclined to make varieties of
