 Fruticetum Vilmorinianum, Les Barres, Nogent-sur-Vernis- 

 son, Loiret, France. Purchased from M. Maurice Vilmorin.

Rubus giraldia,nus Focke. (Rosaceae . ) 40594. Plant of a 

 bramble from Elstree, Herts, England. Presented by the 

 Hon. Vicary Gibbs. "A vigorous, deciduous shrub up to 8 or 

 10 feet high. Inflorescence a terminal panicle, the flow- 

 ers small and of little beauty, purple, fruit black. Na- 

 tive of China, first found in the province of Shensi by 

 Giraldi, later in Szechuen by Wilson, who introduced it in 

 1907. Its claims to recognition in the garden are its re- 

 markably white stems, which are as striking in this re- 

 spect as those of R. bifloi*us , and its pendulous branches, 

 which give a remarkable fountain-like aspect to the shrub."

 p. 458.) 



Ulmus pumila L. (Ulmaceae . ) 40507. Cuttings of an elm 

 from the Botanical Garden at Pekin. "A weeping variety of 

 the very drought-resistant north Chinese elm, not growing 

 apparently to very large dimensions. Of value as a char- 

 acteristic ornamental tree, especially fit for cemeteries 

 and for parks In cold and semi-arid sections. Shows up 

 particularly well when planted along embankments alongside 

 water expanses. Chinese name Lung chao yu shu, meaning 

 'Dragon's claw elm tree. 1 " (Meyer's introduction and de- 

 scription. ) 



Ziziphus Jujuba Miller . (Rhamnaceae .) 40506. Cuttings of 

 a jujube from near Pinchow, Shensi, China. "A local vari- 

 ety of jujube, having large and heavy fruits of elongated 

 form; considered to be the second best jujube in China, the 

 Pai lisiang chen variety coming first. Color of fruits reddish- 

 brown, meat quite solid and very sweet, size of ten as large 

 as small hens' eggs. Trees of thrifty growth, attaining 

 remarkable dimensions for jujubes, trunks being seen of 1|- 

 foot in diameter. The trees are almost spineless when old 

 and sucker but very little. Apparently not attacked by 

 'bunch disease 1 , although infected wild bushes were seen 

 in close proximity. Propagated by suckers exclusively. 

 The wood of this jujube is extensively used in the manufac- 

 ture of combs and in all sorts of turnery work, this indus- 

 try having its seat in and around the village of Ta fu tze. 

 Chinese name, Chin tsao and Fei tsao , meaning 'Golden jujube,' 

 and 'Fat jujube .'" (Meyer ' s introduction and description.)
