Japanese Wineberry. — Canes biennial, 1-3 m long, robust, arching, often rooting at 

 the tip, terete, villous and densely covered with stalked, red-brown glands of various length, 

 mixed with scattered, brown, straight prickles, as is the whole plant, the petioles, petiolules, 

 midveins and the inflorescence. Leaves of the canes 3-foliolate, some lower ones often 

 5 -foliolate, dark green and sparingly pilose or glabrate above, densely white tomentose 

 beneath, simply or doubly toothed; teeth broad, obtuse, mucronate; stipules filiform; 

 petiole about as long as the lower leaflets; these obliquely ovate, with a short point, almost 

 sessile, terminal leaflet stalked, large, cordate-ovate or somewhat 3-lobed, suddenly con- 

 tracted into a short narrow point, from the middle lobately toothed. Flowering shoots 

 often rather long with similar leaves; flowers near the top of the branches, the lower ones 

 in stalked, few-flowered axillary clusters, the upper ones in a short raceme, the whole 

 inflorescence extremely glandular; bracts linear; calyx-lobes long acuminate, tomentosa 

 above, spreading at first ; petals short, obovate, pink. Fruit roundish, bright red, acidulous, 

 easily detaching from the yellow receptacle and disc.
