﻿46 SEEDS AND PLANTS IMPORTED. 



40560. Swietenia mahagoni Jacq. Meliacese. Mahogany. 



From Elliotts Key, Fla. Presented by Dr. John Gifford, Cocoanut Grove, 

 Fla. Received April 19 ? 1915. 



" Seeds from a tree on Elliotts Key. I thought it of special interest, because 

 it is the seed of the true mahogany from a native tree of Florida. Just now the 

 seed is scarce, but at times a wagonload of the capsules could be obtained, since 

 the tree is quite common on the keys and lower mainland of this State. It is 

 called Madeira here, and many persist in the foolish belief that it is not the 

 true mahogany of commerce." (Gifford.)

From Elstree, Herts, England. Presented by Mr. Vicary Gibbs, Aldenham 

 House Gardens. Plants received April 22, 1915.

 (Sargent, Plantae Wilsonianae, vol. 1, p. 375.) 



40563. Berberis subcaulialata C. K. Schneider. 



" This species belongs to the same group as B. stapfiana ( S. P. I. 

 Nos. 37975 and 40150), but it has globose fruits ripe in November, 

 more distinctly angled branchlets, and larger leaves ; the general 

 aspect is otherwise very similar." (W. J. Bean, Trees and Shrubs 

 Hardy in the British Isles, vol. 1, p. 2^9.) 

 40564 and 40565. Bettjla spp. Betulaeese. Birch. 



40564. Bettjla japonica maxdshurica (Regel) Winkler. 



" AVilson No. 4088. A gray-barked tree 10 to 25 meters tall, in 

 girth 1.5 to 2.4 meters, from Chetoshan, west of Tachienlu, western 

 Szechwah, at altitudes of 2,800 to 3,700 meters, September, 1910." 

 (Sargent, Plantae Wilsonianae, vol. 2, p. Jf61.) 



40565. Betuea occidentalis Hooker. 



" There is a good deal of confusion in regard to this tree, and it 

 has been called B. occidentalis (Sargent) ; B. papyrifera var. lyal- 

 liana (Koehne) ; and B. papyracea var. occidentalis (Dippel). The 

 name occidentalis was founded by the elder Hooker in 1839 on 

 specimens of three distinct birches. As it might with equal pro- 

 priety be given to any one of them, it is better to drop it altogether. 

 B. lyalliana is one of the very finest of birches and reaches some- 

 times 120 feet in height; bark reddish brown to whitish, peeling. 

 Young shoots warted, downy, yellowish brown. Leaves ovate with 

 a rounded or heart-shaped base, ordinarily 3 to 4 inches long, but on 

 young trees often over 5 inches long ; hairy along the midrib and 

 veins beneath; veins in 7 to 10 pairs. The tree is no doubt closely 

 allied to the paper birch, but Sargent, who regards it as specifically 

 distinct, distinguishes it by its downy, fruiting scales, its brown
