468 RUBUS 



a grey felt beneath. Flowers white, f in. across, produced in the leaf-axils 

 and at the end of the short side shoots on bristly slender stalks. Fruit 

 red, conical. 



Native of N. America from Labrador south to the Carolinas, and westward 

 to British Columbia and New Mexico. It fills in the New World the place 

 of R. Idasus in the Old. The two species are closely allied, but this American 

 one is easily distinguished by its bristly stems and flower-stalks. It is the 

 parent species of garden races grown largely in N. America, such as the 

 " Cuthbert " and " Hansall " raspberries. This is its chief interest ;- it is not 

 worth cultivation except where collections are maintained. 



R. SWINHOEI, Hance. 



(R. hupehensls, Oliver.} 



A prostrate or climbing evergreen shrub, with round, slender, dark- 

 coloured stems, thinly furnished with a cobweb-like down when young, and 

 armed with a few small decurved spines. Leaves simple, oblong-lanceolate ; 

 3 to 4-^ ins. long, by about i^ ins. wide ; the base rounded, the apex long- 

 pointed, margins finely toothed ; veins in nine to twelve pairs ; upper surface 

 smooth except for tiny bristles along the veins, lower one covered with a 

 close grey felt ; leaf-stalk j to ^ in. long. Flowers usually three to seven in 

 short, terminal, very glandular racemes, of little or no beauty ; calyx covered 

 with grey felt like the leaves ; petals soon falling. Fruit described as at 

 first red, then black-purple, austere. 



Native of Central China and Formosa; originally described in 1866, but 

 introduced to gardens by Wilson from Hupeh in 1907. The foliage is 

 handsome, and distinct from that of any other cultivated species except 

 R. malifolius; the inflorescence also is conspicuous in its glandular hairiness. 



R. THIBETANUS Franchet. 



(R. Veitchii, Rolfe^ 



An erect deciduous shrub, 6 ft. or more high ; stems biennial, smooth, 

 round, covered with a purplish bloom, and set irregularly with straight, 

 slender prickles. Leaves pinnate, 4 to 9 ins. long, composed of seven to 

 thirteen leaflets, the main-stalk prickly ; leaflets oval or ovate, more or 

 less oblique, stalkless, coarsely and angularly toothed, dark lustrous green, 

 and with minutely silky hairs above, whitish felted beneath; the lowest leaflets 

 are i to 2 ins. long, each successive pair diminishing in size towards the 

 apex of the leaf which is terminated by a long, deep-lobed leaflet. Flowers ^ 

 in. across, slender-stalked, solitary in the leaf-axils, or a few together in 

 terminal flattish panicles ; x the calyx very downy, with triangular lobes; petals 

 purple. Fruit roundish, in. across, black with a bluish bloom. 



Native of W. China ; discovered and introduced by Wilson for Messrs 

 Veitch, with whom it flowered in August, 1908. Mr Wilson informs me he 

 found it in the Min River Valley at elevations of 4000 to 6000 ft., where it is 

 rare. Of the newer Chinese Rubi it is one of the most distinct and attractive- 

 looking, both for its blue-purple stems and very handsomely cut foliage. 



R. THYRSOIDEUS, Wimmer. 



A strong-growing shrub, with arching, ribbed stems becoming nearly or 

 quite free from down, but armed with straight or slightly hooked prickles. 

 Leaves composed of five leaflets, the terminal one of which is ovate, often
