Alnus 951 



A specimen is growing at Milford House, near Godalming, which was planted 

 by the famous botanist and traveller, Phillip Barker Webb. The present owner, 

 R. W. Webb, Esq., informed us in 1905 that it was very healthy, measuring 8 feet 

 in girth, and estimated to be about 50 feet in height. 



There is a fine tree growing near the pond in front of the palm-house in Kew 

 Gardens, which is 7 1 feet high by 5 feet 8 inches in girth. At Tortworth, a tree 

 measures 60 feet high by 6 feet in girth ; and at Waterer's Nursery, Knaphill, 

 Woking, another is 50 feet by 5 feet 10 inches. 



At Nuneham Park, Oxford, a tree, growing on hilly dry ground, on the green- 

 sand formation, measures 51 feet by 5 feet 5 inches, and is very thriving. Elwes 

 has seen a tree at Bicton, measuring 65 feet by 5 feet 10 inches, and another at 

 Melbury, where it grows vigorously and fruits. 



In the playing fields at Eton, on the banks of the Thames, there are two trees, 

 the larger of which is 40 feet high by 6 feet 4 inches in girth. These were in full 

 foliage on 17th November 1907, having scarcely lost a leaf, and were bearing fruit. 

 They have not developed tall straight stems, as in the other places where the tree is 

 thriving ; and this is probably owing to their position being exposed to easterly and 

 north-easterly winds. At Ponfield, Herts, a young tree 35 feet by 2 feet 4 inches 

 in 1906 is doing well on dry soil ; and there is a good specimen in the Cambridge 

 Botanic Garden. Another at Yattendon Court, Berks, is 50 feet by 3 feet 8 inches. 



In Scotland it also grows well at the Botanic Gardens, Edinburgh, where there 

 is a tree 60 feet by 5 feet 10 inches ; and in the west at Castle Kennedy, and at 

 Monreith, where Elwes saw a tree 30 feet high, bearing cones in September 1906. 



There is a fine specimen in the Glasnevin Botanic Garden, which is 64 feet 

 high by 5 feet 4 inches in girth. (A. H.)
