Rodgersia aesculifolia, Bat. By Baccarini Pasquale {BnlL 

 B. Soc. Tosc. Ort. 6, June, 1901, p. 172).— Genus founded by Asa Gray 

 at the expense of the older Asiilbe of Hamilton, thus separating the forms 

 having carpels fused below, and with digitate and not tripartite leaves. 

 This species was first discovered by P. David, in Mu-pin in Japan, in the 

 year 1869, but was not described until 1893, and by Batalin. It has 

 since been found in various regions of China, amongst others in Si-Ku- 

 Tzui, at an altitude of 800 to 1,200 metres above sea-level. 



It flowers in its native habitats from May to July, and fruits in 

 August. The leaves resemble those of the Indian Chestnut, being broad, 

 peltate, palmatifid, with cylindric petiole ; the leaflets are obovate, 

 acute or rounded at the apex, glabrous ; the principal veins of the lower 

 surface are rough with patent hairs, the margin is either simply dentate 

 or doubly serrate. The inflorescence consists of an elegant panicle, 

 conical in sliape and about a foot in length. 



The flowers are minute and not excessively densely packed ; the calyx 

 is shortly turbinate, five-lobed, the sepals white, flushed with rose towards the 

 tip, and covered on the lower surface with minute hairs. The ten stamens 

 are as long as tlie calyx-lobes, witli yellow globular anthers ; the two 

 carpels are also wliite at the time of flowering. 



After fertilisation the calyx turns green and the stamens become 

 erect Avithout falHng apart, the filaments only turning brown. 



The whole plant has both a bizarre and elegant appearance, and as it 

 is hardy and easy of cultivation, it is certainly wortliy a place in the 

 ornamental garden. — W. C. TI'.

Rose Border, An Ideal [Gard. Mcuj. 2,814, p. 353,8/6/1901).— 

 The writer advocates the planting of Roses in masses of distinct colours, 

 and enumerates a selection of varieties that harmonise or contrast in 

 colour. If the suggestions are carried out, a beautiful Rose border would 

 doubtless result. — TT'. G.
