RARE TREES AND SHRUBS IN THE ARNOLD ARBORETUM, U.S.A. 25 



to suit very well a beautiful Japanese and Chinese climber, Acti- 

 nidia polygama. In the vicinity of Boston a good many houses 

 have fine specimens of it on trellis work with a north exposure. 

 The drooping and fine foliaged shoots are very rich and effective. 

 Facing the south Clematis panicidata is sometimes planted. 

 This is a late bloomer, and the plentiful white flowers will not 

 open before late in August or September. Except for Southern 

 England this creeper will probably not be as interesting as it is 

 on the other side of the ocean. 



A good many Barberries are cultivated in the Arboretum. 

 One of the finest is Berberis Thunbcrgii. Some fine figures of 

 the plants were given in the Garden and Forest and other 

 horticultural papers. But the bush far surpasses even the 

 illustrations, and the specimen growing in the nook of Professor 

 Sargent's rock garden is indeed a marvel. 



Like Cercidiphyllums and Gordonias, the Stuartias (or 

 Stewartias) are difficult to manage. I am not acquainted with 

 any successful cultivator of Stuartias in France, and for my own 

 part I ultimately lost all my plants. Even in America I saw 

 few really good cultivated specimens of the native species, and 

 in the Arboretum they are not to be compared as to the symmetry 

 of branches, the abundance and healthy appearance of the foliage, 

 with a beautiful new species introduced there from Japan. The 

 plant was as yet without a specific name at the time of my visit ; 

 it was 10 feet high, in the best possible condition, and flower- 

 buds were already visible. 



A good many Maples are to be found in the Arboretum and 

 in the gardens of the Sargent family. Nearly all the East 

 American species have been long known in Europe, and I pass 

 them by ; but I was surprised to see so many forms of the 

 Japanese Acer polymorphum near Boston. Some of them are 

 very hardy. Another very fine small tree is Acer or Negundo 

 cissifolium, also a Japanese (see fig. 1, p. 26). The pointed 

 leaves make a very dense but graceful mass of foliage. The 

 colour is very good, the old leaves being green, and the new ones, 

 and the top of the shoots, brownish-red. Acer truncation, with 

 its fine slender shoots and loose five-lobed leaves, is also very 

 graceful, and of the same colour in early summer as the last. 



The use of the Ampelopsis Veitchii as an ornament for 

 city houses is so general that the plant has received in New
