that has yet flowered is M. cuneifolia. Its panicles of small white 

 flowers are scented like Hawthorn (Fig. 50). 



The genus Sty rax, hitherto fairly well known by 5. japonica, 

 has been recruited by several new species. The two best are S. 

 Wilsonii, shown very prettily in flower by Miss Willmott before 

 this Society last year, and S. Hemsleyana, of which the flnest example 

 in the country grows in the grounds of Caerhays Castle. Its flowers 

 recall those of Styrax Ohassia. S. Veitchiorum with large pinnate 

 leaves like a hickory is very striking. 



A considerable number of Spiraeas have been sent to us from 

 China, but on the whole they do not add much that is new or of value 

 to our collections. The two best, I think, will prove to be Spiraea 

 Veitchii, the finest species of the canescens or flagelliformis group ; 

 and Spiraea arborea, which is a close ally of S. Lindleyana. It is, 

 however, said to assume a tree-like habit and become 30 feet high — 

 rather remarkable dimensions for a Spiraea (Fig. 51). 



Potentilla Veitchii (Fig. 52) is closely related to our old friend in 

 gardens, P. fruticosa. It has white flowers and foliage of a silvery 

 hue, and is one of the most striking of its group. 



Of Deutzias the finest, I think, is D. longifolia, which has several 

 times been shown in first-rate condition at the Society's meetings. 

 Some forms of Deutzia discolor are also very fine. (Fig. 53.) 



Another genus of shrubs much enriched by Wilson's discoveries 

 is CoTONEASTER. Previous to their introduction the majority of 

 cultivated Cotoneasters, and the best of them, were of Himalayan 

 origin. These new Chinese species have brought several quite fresh 

 types into gardens. There is the group of evergreen species, for instance, 

 with rugose leaves, represented by Henryana, hullata, and the forms 

 of salicifolia, all with handsome red fruits ; the prostrate C. Dammeri 

 or humifusa, and the very graceful C. Dielsiana {applanata). C. 

 divaricata is more in the way of C. Simonsii. Altogether Wilson 

 has added to our collections at least two dozen new Cotoneasters, 

 most of them quite distinct from anything we had before. Considering 

 how beautiful they are, how easily accommodated in gardens, this 

 number represents a very substantial contribution to the garden 

 flora. 



Diospyros Lotus is an ally of the Persimmon and Kaki (whose 

 fruits are often to be purchased in London shops). It has been culti- 

 vated in South Europe for centuries, and in a few places in England 

 since early in the seventeenth century. Wilson introduced it 

 abundantly from China, where it grows 80 feet high and has a trunk 

 12 feet in girth. 



Of climbers the two chief genera are Clematis and Vitis. The 

 various forms of Clematis montana, and especially the variety rubens, 

 in combining a great beauty with a hardy and accommodating nature, 

 make some of Wilson's choicest introductions. A very promising 

 species also is Clematis Armandii, especially for wall cultivation. It
