30 THE SMALL FRUITS OF NEW YORK 



Most of the species of this subgenus are North American, two are 

 natives of Japan. They are perhaps of more ornamental value than they 

 will ever be as fruit plants.

Flowering Raspberry. — Erect shrub, with perennial stems, 1-3 m high, bushy. Stems 

 with pale brown flaky peeling bark, in the young parts more or less villous and densely 

 glandular-hispid. Leaves large, simple, maple-like on long stalks, cordate at base, roundish 

 in outline, 5- to 7-lobed, rather firm, green and sparingly hairy on both sides, lobes acute, 

 lobulate, fine and sharply doubly toothed, the middle lobe the largest, 10-30 cm wide. 

 Petioles roundish, glandular-hispid, about as long as the blades, stipules acute. Flower.'; 

 numerous, subcorymbose, fragrant, 4-5 cm across; pedicels and calyxes densely beset witli 

 stalked brownish glands; caljoc-lobes ovate, caudate or suddenly contracted into a long 

 narrow point; petals roundish, deep rose colored; stamens very numerous, shorter than the 

 petals, pistils numerous, tomentose. Fruits red, flat, round, tasteless. 



Eastern North America; from Nova Scotia to the Saskatchewan River, 

 south to Michigan and in the mountains as far as Tennessee and Georgia, 

 chiefly in half shady places, in glens, on wet rocks, woods, and roadsides. 

 Not much of a fruit plant, but a very ornamental shrub; introduced into 

 Europe as early as 1770 and now commonly cultivated. It flowers from 

 June to September. 



A rather constant species. The following varieties are worth noting: 



Var. columbianus. Millspaugh W. Va. Sta. Bui. 24:355. 1892. Rubus columbianus, 

 Rydberg in Britton Man. 495. 1901; Rubacer columbianus, Rydberg N. Am. Fl. 22:426. 



1913- 



Leaves deeper cut and the lobes lanceolate, acuminate, incised, dentate or doubly 



toothed. ' 



Western Virginia. 



Var. albidus. Bailey Stand. Cyc. Hort. 5:3024. 1916. 



Flowers whitish and bark lighter colored. 



R. odoratus hsLS been crossed with R. idaeus, and the hybrid is named:
