of Korea, Manchuria, and Japan. The tree is interesting and very dis- 

 tinct among cherries because of the conspicuous bracts on the inflores- 

 cence, which remain until the fruit is ripe; but neither in flower nor 

 fruit is it particularly attractive as cherries go. For its autumn color- 

 ing it may prove valuable, as it turns a brilliant scarlet both in Japan 

 and North America. It is very hardy." (IF. J. Bean, Trees and Shrubs 

 Hardy in the British Isles, vol. 2, p. 2J t 3.)

42585. Rubus coreanus Miquel. Rosaceae. Bramble. 

 "A deciduous shrub, 8 to 10 feet high (it has been found 15 feet high in 



a wild state), with erect or arching, stout, biennial stems, branching 

 toward the top, and armed with stiff, broad-based spines. Leaves com- 

 posed usually of seven dark lustrous-green leaflets. Flowers borne in 

 flattish clusters, terminating short shoots from the wood of the previous 

 year. Fruit of various colors from red to nearly black, edible but small, 

 and of poor flavor. Native of Korea and China ; introduced from the latter 

 country in 1907 by Wilson, who found it at altitudes up to 6,000 feet. It 

 is one of the handsomest of all Rubi in its vigorous blue-white stems and 

 beautiful pinnate foliage, and may prove a valuable acquisition in gardens 

 should it be quite hardy." (IF. J. Bean, Trees and Shrubs Hardy in the 

 British Isles, vol. 2, p. Ji56.)

42586. Rubus biflorus quinqueflorus Focke. Rosaceae. Bramble. 

 "A deciduous shrub, with erect stems up to 10 feet high and 1 inch 



thick at base, covered with a thick, white, waxy coating and armed with 

 straight, broad-based spines. Toward the top the stems branch freely, 

 the branches also being white, and, like the leafstalks and often the midrib, 

 spiny. Leaves 4 to 10 inches long, composed of three to five leaflets, 

 which are dark green above, covered beneath with a close white felt. 

 Flowers terminal and axillary, white, three-fourths of an inch across; 

 fruits edible. Native of the Himalayas up to 10,000 feet; introduced in 

 1818. Among the longer cultivated, white-stemmed raspberries this is by 

 far the most effective, although it is no doubt equaled by some of the 

 newer Chinese species. Its flowers are of little consequence, being small 

 and of little beauty. It should be raised from seed (which ripens here), 

 and planted in groups of not less than half a dozen. The soil should be 

 a good loam, the aim being to produce stout thick stems, for the stouter 

 they are the whiter and more persistent is their waxy covering. After 

 the previous year's stems have flowered and borne fruit, they should be 

 cut away (usually about August), leaving only the virgin growths of the 

 year. During autumn and winter a group of this Rubus makes one of 

 the most striking plant pictures in the open air. Var. quinqueflorus. — A 

 vigorous Chinese form introduced by Wilson in 1907, with the terminal in- 

 florescence composed most frequently of five (sometimes up to eight) 

 flowers. In the type they are usually two or three." (IF. J. Bean, Trees 

 and Shrubs Hardy in the British Isles, vol. 2, p. h^h)

42587. Rubus lasiostylus dizygos Focke. Rosaceae. Bramble. 

 "An erect-growing deciduous shrub with biennial stems 4 to 6 feet 



high, covered with a blue-white, waxy bloom, and closely set with bristle-
