134 The Ottawa Naturalist. [Oct. and Nov. 



A. dasycarpuni, Ehrh. — White or Silver Maple. Eastern 

 North America. Planted 1890. Hardy. This is a large rapid 

 growing native tree, but should not be planted for shade where 

 the sugar maple will succeed. 



A. glabnmi, Torn and Gray. — Smooth Maple. Western 

 North America. Planted 1891. Hardy. A very pretty shrub, 

 with glossy deep green foliage. It is a native of British 

 Columbia. 



A. Heldreichi, Orph. — Eastern Europe. Planted 1896. 

 Hardy. As yet there is nothing to recommend this as an orna- 

 mental tree, but it has made good growth and seems quite hardy. 



A. insigne, Boiss. and Buhse. — Northern Persia. Planted 

 1896. Tender. This tree has been killed to the ground during 

 each of the past two winters. 



A. japonicum, Thunb. — Japanese Maple. Planted 1897. 

 Hardy. It is too soon yet to say whether this will succeed here 

 or not. One specimen received from Tokio last year proved 

 quite hardy. It is a beautiful little maple with finely cut foliage. 



A. Myabei. — Japan. Planted 1896. Hardy. This maple 

 is not recorded in the Index Kewensis. The specimens at the 

 Experimental Farm were procured from the Arnold Arboretum, 

 Boston. It is not very ornamental at present, but is a strong 

 growing species. 



A. monspessulanum, L. — Montpellier Maple. Mediterranean 

 region. Planted 1896. Half hardy. A small tree with three- 

 lobed leaves, the lobes being equal and entire. Rather orna- 

 mental. Some specimens of this tree have proved quite hardy. 



A. Negundo, L. — Box Elder, Manitoba Maple. Canada, 

 United States. Planted 1890. Hardy. This is a very rapid 

 growing tree, and fairly ornamental, but it is seldom that sym- 

 metrical trees are formed and often they are disfigured by the 

 limbs being Broken off by the wind, as the wood is soft. This 

 tree should only be planted in the coldest parts of the country 

 where few trees will grow, as there are so many other trees of 

 greater merit that will succeed in climates as severe as that of 

 Ottawa.
