species, furnished with small, closely set leaves, 1 in. long by f in. broad, 

 and rigidly spinous. The berries are red and freely produced. For use 

 as a hedge or shelter plant this Holly is eminently suited, as from its 

 dense growth and rigid spines it positively defies penetration. 



The genus Vitis is represented by many species, several of which 

 promise to be of great horticultural value by reason of the elegant 

 outline of their leaves and the brilliant tints assumed in the autumn 

 months. 



Vitis mcijaphylla (the Wonderful-leaved Vine) is remarkable in having 

 bipinnate leaves, in this respect resembling the allied genus Leca. The leaf- 

 lets are petiolate, 2-4 in. in length, ovate, with dentate margins. (Fig. 16.) 



Vitis Romaneti is a handsome -leaved species with edible fruit, and 

 Vitis armata has branches curiously beset with prickles. (Fig. 17.) Vitis 

 Thomsoni has digitate leaves of a purple colour, and Vitis leeoides is also 

 interesting. Amongst the most promising results of Wilson's journey are 

 these Vines and several other valuable species at present unnamed. 



The natural order Sapindaceai is rich in shrubby plants belonging 

 to favourite garden genera. The genus Acer, as might have been anti- 

 cipated, contains the largest number of species. Dr. Henry states that 

 during an excursion that he made in 1898 into the mountains he found 

 sixteen distinct species, of which nine were new. 



Of several growing at Coombe Wood new to cultivation, Acer Henry i, 

 Acer oblong um, Acer Francheti are amongst the most striking. These 

 Maples formed the subject of several articles in the Gardeners' Chronicle 

 during January 1903 from the pen of Dr. Henry. 



Closely allied to Acer is the new genus Dipteronia, including two 

 species, one of which, Dipteronia sinensis, is in cultivation at Coombe 

 Wood, where it has withstood fifteen degrees of frost. In the mountain 

 forests of Hupeh it attains a height of from ten to twelve feet. The 

 leaves are impari-pinnate, with six to seven, pairs of ovate-lanceolate, 

 acute leaflets, glabrous or occasionally pubescent, with sharply serrated 

 margins. The flowers are small, polygamous, and are borne in dense 

 panicles terminating the branches. The fruits, freely produced, consist 

 of two divergent carpels, which are connate at the base and furnished 

 with a membranous wing all round the seed. A single carpel somewhat 

 resembles the samara of the Wych Elm or of Ptelea trifoliata. The 

 individual flowers are small, but, being produced in a dense panicle, 

 showy. (Figs. 1H and 19.) 



The order Rosacea? is the richest numerically in genera and species 

 of plants of horticultural interest, such genera as Rubas, Cotoneastcr, 

 I'm us, Sptra*a, Rosa, &e, being largely represented. 



Cotoneastt r species (No. 13H4) is possibly the most valuable of this 

 geQUfl received. It is a shrub with ovate-lanceolate leaves, 2-2 i in. long, 

 shortly petiolate, with entire margins, the upper surface strongly veined 

 and slightly pilose, the lower covered with a dense woolly tomentum 

 which gives it a white appearance. 



The flowers ire densely borne in corymbs terminating dwarf branches 

 ■Jong the whole Length of the shoot, and are followed by bright red 

 fruits ; altogether an unusually promising shrub.
