310 BUSH-FRUITS 



The eaneseent, dense tomentum of the ovaries is seen, even on the 

 mature drupelets. 



6. R. STELLATUS, Smith. 



Stem herbaceous, simple, 1 -flowered, leaves cordate, rugose, 

 deeply 3-lobed or 3-parted, often compound, serrate; stipules 

 ovate, acute or obtuse; peduncles short; segments of the calyx 

 linear-lanceolate or linear, sometimes slightly spatulate; petals 

 oblong, erect. 



Distribution. — Behring region, Wrangel Land, Aleutian Islands. 



7. R. NIVALIS, Dougl. 



Low, not more than 6 inches (1.5 decimeters) high, from a 

 long, trailing, frutescent stem; spines rather stout, recurved; 

 leaves cordate, 3-lobed, very rarely almost compound, very sharply 

 toothed, glabrous, the petioles and veins armed with recurved 

 prickles, stipules ovate, acute, prominent, often toothed; pe- 

 duncles short, 1- or 2-flowered; calyx lobes lanceolate, pubescent; 

 petals small, lanceolate, very acute; fruit red, sour; seeds few, 

 large and wrinkled. 



Distribution. — In the Bitter Root Mountains and northward on 

 high ridges of the Rocky Mountain system; also, in the Cascade 

 Mountains. 



This bears some resemblance to B. vitifolius, but may be dis- 

 tinguished from that species by the simple leaves, sharp petals, 

 lack of pubescence, and especially by the simple inflorescence. 

 Professor Piper writes that "In deep woods it never fruits, but on 

 open, rocky places bears an abundance of sour red berries. The 

 plant is prostrate, like B. vitifolius." 



8. R. CRAT^GiFOLius, Bunge. Chinese Raspberry. 



Stems shrubby, upright or drooping, 3-6 feet (1-2 meters) high, 

 armed with few straight prickles; leaves glabrate, cordate, ovate, 

 acute, 3-5 lobed, lower one smallest, middle lobe long, acuminate, 

 often narrower at base, lateral lobes oblique, all doubly serrate, 

 petioles and veins beneath armed with scattering, minute, re- 

 curved prickles; stipules linear, scarious, leafy shoots terminating 

 in a several-flowered, cymose cluster; flowers white, nearly half 

 an inch broad, inconspicuous; calyx slightly pubescent, lobes 

 triangular, acuminate, bearing glandular tipped hairs along the 

 margin; petals small; fruit orange -scarlet, nearly hemispherical 

 (Fig. 53). 



Original distribution. — Manchuria, Northern China and Japan,
