RUBUS 465 



Native of Eastern N. America, and the parent species of several races of 

 garden raspberries largely grown in America, the best known of which are the 

 " Gregg," " Hillborn," and "Ohio." In this country it is only worth growing 

 for the long, arching, blue-white stems, and even in this respect it is not 

 equal to R. biflorus or R. lasiostylus. The tips of the arching shoots often 

 reach the ground and there take root. Allied to R. strigosus, it differs in its 

 black fruits and glaucous stems. 



Intermediate between occidentalis and strigosus is R. NEGLECTUS, Peck. 

 It is thought to be a natural hybrid from them, having dark red fruits and 

 prickly blue- white stems. Introduced to Kew in 1893. 



R. ODORATUS, Lmnceus. 



(Bot. Mag., t. 323.) 



A vigorous, deciduous shrub, with stout, erect, very pale brown stems up 

 to 8 ft. high, bark peeling ; young stems covered with glandular hairs. 

 Leaves simple, amongst the largest of hardy Rubi, five-lobed, vine- 

 like, 4 to 10 (or even 12) ins. across ; lobes pointed, sharply and irregularly 

 toothed, hairy on both sides, but especially beneath, soft and velvety to the 

 touch. Flowers fragrant, bright purple, i^ to 2 ins. across, borne in large, 

 branching, corymbose clusters at the ends of the shoots ; the stalks con- 

 spicuously furnished with dense glandular hairs, the calyx similarly covered, 

 eacri of its five divisions narrowed to a tail-like point. Fruits flat and broad, 

 red when ripe, but rarely seen in this country. 



Native of Eastern N.America ; introduced in 1770. Next to R. deliciosus, 

 this is perhaps the most ornamental of Rubi in regard to blossom. It 

 flowers from July to September, and few shrubs at that time equal it in 

 beauty and fragrance. It loves a semi-shaded spot, where its flowers are 

 protected from the fierce mid-day and early afternoon sun ; in such a place 

 the blossoms last longer. It is a rampant grower, and soon forms a thicket ; 

 good soil should be provided and the plants are all the better if pulled apart 

 every few years, and planted more thinly. The old stems should be removed 

 every winter. It is very similar in growth to R. nutkanus (q.v.\ but commences 

 to flower a month later. 



R. OMEIENSIS, Rolfe. 



A large straggling shrub, with round stems, unarmed, but furnished with 

 small, stellate hairs. Leaves of maple-like form, five-, or obscurely seven-lobed, 

 with a heart-shaped base ; 3 to 7 ins. long and as much wide ; irregularly 

 toothed, stellately downy beneath, less so above ; stalk 2 to 3 ins. long ; 

 stipules i to | in. long, cut up into deep, narrow segments. Panicles many- 

 flowered, terminal ; flowers \ in. across, with downy stalks ; calyx downy, the 

 lobes pointed, triangular ; petals purple. Fruit black, well-flavoured, 

 ripening late. 



Native of W. China, and found on Mt. Omi by Wilson, who introduced 

 it for Messrs Veitch, with whom it flowered in August 1908. It grows up to 

 6000 ft. elevation, and will probably be perfectly hardy. It makes growths 

 10 or 12 ft. long in a season. The stipules are rather remarkable. 



R. PALMATUS, Thunberg. 



(Bot. Mag., t. 7801.) 



A deciduous shrub, 5 or 6 ft. high in the open (thrice as much in a cool 

 greenhouse) , stems not downy, but armed with small, flattened prickles.
