fornia, where it is made to include at least three other species in the coast region 

 alone, and none of the forms credited to it from the Sierras belong with it, for it 

 does not occur there at all. It extends into Oregon, and perhaps into Washing- 

 ton on the north.

Slirub several feet high, v,dth light brov\-n, tortuous branches, 

 minutely pubescent and thickly beset with stout, rigid, horizon- 

 tal, yellow prickles, some gland-tipped, generally small on the 

 new growth, and increasing in size with age; axillary thorns 

 triple, stout, distinct at base, middle one longest, becoming 

 15mm. long, lower part pubescent, upper glabrous. Leaves 

 thin, three-lobed or somie five-lobed, with the basal lobes small, 

 2-4cm. wide, orbicular reniform, incisely dentate, minutely pu- 

 bescent and dotted with sessile glands on the lower surface, 

 almost glabrous on the upper; petioles about as long as the 

 blade, totnentose and slightly glandular. Peduncles one- to 

 three-flowered, i-2cm. long, ascending, slender, sparingly pilose 

 and clothed with gland-tipped hairs; pedicels less than half as 

 long, occasionally longer; bracts orbicular or lobed, clasping, 

 acuminate to obtuse. Calyx pubescent and glandular; tube a 

 little longer than the ovary; divisions icm. long, surpassing the 

 rest of the flower Vv-hen reflexed, 3mm. wide, lov/er part purple, 

 near the apex greenish, obtuse. Petals white, broadly obovate 

 when spread out, acute, narrowed to a short claw, involute, 4mm. 

 long. Stamens with broad filaments dilated at base, as broad 

 and long as the anthers; these about 3mm. long, sagittate at 

 base, tipped with a blunt mucro. Styles surpassing the sepals 

 in the opening flower, divided about half; stigmas small, capi- 

 tate; ovary globular, tomentose, and densely clothed with pur- 

 plish bristles, some near the calyx gland-tipped. Fruit purple, 

 more or less densely clothed with sti:5, spreading prickles, 

 2-5mm. long. 



This species is nearest to R. Me7zziesii Pursh but differs in 

 the glandular pubescence, the shape and texture of the leaves, 

 the size of the flower, and shape of the parts.
