472 BUSH-FBUITS 



ance; petioles pubescent; racemes upright, corymbose; pedi- 

 cels long filiform, the lower ones compound; flowers small; calyx- 

 tube flat; lobes ovate or oblong, rose colored, several times as 

 long as the tube; petals minute; stamens and 2-cleft style very 

 short; berry apparently smooth or leathery. 



Northern part of Lower California and islands of southwestern 

 California. 



36. R. LAXIFLORUM, Pursh. R. Hoivellii, Greene. R. acerifolium, 

 ■ Howell. 



Stems ascending, 3-8 feet (9-24 decimeters) long, unarmed; 

 leaves 2-3 inches (5-7.5 cm. ) in diameter, cordate, or sometimes 

 truncate, mostly 5-lobed; lobes doubly and somewhat finely and 

 sharply incised, bearing very minute resinous dots beneath; 

 petioles long and slender, dilated and ciliate with glandular- 

 tipped hairs at the base ; shoots subtended by prominent scarious 

 bracts ; racemes, ovary and calyx glandular pubescent ; bracts 

 slender, as long as the pedicels; petals minute, red, spatulate; 

 calyx-tube broad, saucer-shaped; lobes broadly obovate or spatu- 

 late; anthers very short and broad; filaments flattened; style 

 deeply 2-cleft; fruit purple or black, sparingly glandular bristly. 



Oregon and Washington. 



This is apparently a western ally of R. prostratiwi, differing 

 from that species chiefly in the longer bracts, larger calyx- lobes, 

 and the resinous dots on the under surface of the leaves. 



37. RiBES HuDSONiANUM, Rich. 



Upright shrub, 3-4 feet (9-12 decimeters) high; branches erect, 

 thick, the bark scaling off in thin, papery layers ; leaves large, 

 coarsely incised or serrate, nearly glabrous above, with minute 

 resinous dots beneath; petioles long, broadened toward the base, 

 minutely pubescent; racemes erect, long, narrow, many-flowered; 

 pedicels short; bracts minute, deciduous ; calyx -tube short ; lobes 

 lanceolate -oblong, pubescent, whitish, resinous dots extending 

 from the outer surface of the lobes to the peduncles, being 

 thickest on the ovary and pedicels; petals small, obovate, one- 

 fourth as long as the calyx-lobes; stamens as long as the petals; 

 style single or 2-parted; fruit round, black, glabrous. 



Hudson's Bay to the Rocky Mountains, Oregon and northward. 



In the mountains of Oregon the calyx becomes nearly gla- 

 brous and the racemes longer (var. B., Hook.). This species re- 

 sembles R. nigrum in its fruit and the odor of the plants, 



38. R. BRACTEOSUM, Dougl. 



Tall, upright shrvib, 4 10 feet (12-30 decimeters) high, almost 

 glabrous, at least with age, the smaller parts sprinkled with
