like spines. Leaves composed of three or five leaflets, and on young 

 vigorous plants as much as 14 inches long, but usually some 6 or 8 inches 

 long. Flowers small, with reddish purple petals, which are shorter than 

 the calyx segments and soon fall. Fruit 1 inch across, roundish, red, 

 and downy, with an agreeable acid taste. Native of central China; 

 originally discovered in Hupeh by Henry, who sent seeds to Kewin 

 1889, from which plants were raised that flowered in 1894. This is one 

 of the most striking of the white-stemmed brambles. It has lately been 

 reintroduced in quantity by Wilson from Hupeh." (W. J. Bean, Trees 

 and Shrubs Hardy in the British Isles, vol. 2, p. J f 62.) 



42588. Rubus inopertus Focke. Rosacea?. Bramble. 

 A Chinese bramble, growing at altitudes of 600 to 2,200 meters, of 



which Focke says (Sargent, Plantae Wilsonianae, vol. 1, p. 54) : "This 

 Chinese plant seems to be rather constant and looks very different from 

 the tropical R. niveus Thunberg. It is therefore reasonable to separate 

 the two plants specifically, although there occur connecting links in the 

 Himalayas."

42589. Rubus mesogaeus Focke. Rosacea?. Bramble. 

 A slender climbing bramble with stems 4 to 5 meters long, rather small 



flowers, and small globose berries. Native of central China, especially 

 western Hupeh and Szechwan. (Adapted from Focke, Species Ruborum, 

 Bibliotheca Botanica, No. 72, p. 204-) 



42590. Rubus omeiensis Rolfe. Rosacea?. Bramble. 

 A large straggling shrub with round stems unarmed, but furnished 



with small stellate hairs. Leaves of maplelike form, five or obscurely 

 seven lobed, with a heart-shaped base; 3 to 7 inches long and as wide. 

 Stipules one-half to three-fourths of an inch long, cut up into deep 

 narrow segments. Panicles many flowered, terminal; flowers half an 

 inch across with downy stalks; calyx downy, the lobes pointed, trian- 

 gular ; petals purple. Fruit black, well flavored, ripening late. Native 

 of western China, and found on Mount Omi by Wilson, who introduced 

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

 up to 6,000 feet elevation and will probably be perfectly hardy. It 

 makes a growth 10 or 12 feet long in a season. The stipules are rather 

 remarkable. (Adapted from W. J. Bean, Trees and Shrubs Hardy in the 

 British Isles, vol. 2, p. ^65.) 

 For previous introduction, see S. P. I. No. 40195. 



42591. Rubus pubescens Weihe. Rosacea?. Bramble. 

 A very robust bramble, native of central and western Germany, Swit- 

 zerland, France, and England, with strong, thick canes which do not 

 ascend to any height without support. Spines very strong, reddish 

 brown, on broad compressed bases. Flowers appearing in July, conspicu- 

 ous, white, sometimes pale red. Fruit well developed, conspicuous, round, 

 with pleasant flavor. 



42592. Rubus thibetanus Franch. Rosacea?. Bramble. 

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



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