Hevea as yet untried, any of which may also have its ‘‘ Ledger- 
ianas.’’ Besides, itis worth while to find out whether other 
advantageous qualities, such as qualities of the rubber, geogra- 
phical adaptability, etc., are present in the sorts which might 
give good results either by themselves or by crossin 
The establishment of a standard garden, containing every type 
of the genus Hevea, would place inexhaustible material at the 
disposal of the plant breeder, and steps in this direction have been 
taken by Dr. Cramer in the establishment of the selection station 
at Buitenzorg.

TREES AND SHRUBS.

Cladrastis Wiisonii, 7akeda | Leguminosae. | 
Two of the most interesting trees introduced by Mr. Wilson 
from China are two species of Cladrastis, viz., C. sinensis Hemsley 
(see Kew Bulletin, 1913, p. 164) and C. Wils soni. Both belong to 
the true Cladrastis distinct from M aackia, which by Bentham 
and Hooker was united with it. Pr revious to the comparatively 
recent discovery of these two species and another Japanese one, 
Cladrastis was only known by a as ‘aie renee in the Eastern 
United States, the well-known ‘ Yellow wood,” C. tinctoria. 
C. Walsonw is fairly common in the moi set “baal of Western 
Hupeh, but rare in Kiangsi. Farther west it is replaced by C. 
sinensis. In cultivation C. Wilsoniz is extremely rare, and we 
have but one plant at Kew; this was obtained from the Arnold 
Arboretum in 1910. It is possible that it may be in cultivation 
elsewhere under Wilson’s number 1102. 
C. Wilsonii is a tree 15 to 50 ft. high, the trunk up to 1} ft. in 
diameter. Its leaves are deciduous, 9 to 13 in. long, pinnate, 
with nine to fifteen leaflets on each leaf. Leaflets ovate to 
elliptic, 14 to Fy in. long, } to 11 in. wide, the terminal one the 
largest. (On the wild specimens collected in China and preserved 
in the Kew Herbarium the leaflets are fewer on each leaf but indi- 
vidually larger, often 4 in. long and 2 to 2} in. wide.) They are 
dark green above, este eucons beneath, and at maturity paren 
and Maackia.
