80 FOREST TREES. 
tree would be produced much sooner than in any 
other way. It may also be grown from layers, but 
does not root very readily. The seeds should be sown 
in a cool, shaded situation. 
CLADRASTIS—YELLOW WOOD. 
Natural Order, Leguminosae. 
Calyx, five-toothed; standard large, roundish, 
reflexed; the keel petals and wings straight, oblong; 
stamens, ten, distinct; filaments slender, incurved 
above; pod, linear, flat, thin, marginless; four to six- 
seeded ; two-valved. Leaves, pinnate; leaflets, seven 
to eleven, oval or ovate; flowers in panicled racemes ; 
white, showy. 
Cladrastis tinctoria. Virgilia— Yellowwood. 
The Virgilia is a middle-sized tree, rarely exceeding 
forty feet in height, and one foot in diameter. It is 
found in Kentucky and Tennessee, but is hardy 
several degrees further north. It is highly esteemed 
as an ornamental tree. The foliageis handsome, and 
the flowers numerous and showy. They are white, 
and produced in long, pendulous racemes. The wood 
is said to possess valuable qualities, but the rarity of 
the tree precludes the idea of its cultivation for 
timber to any considerable extent. Its growth from 
seed is slow for the first three or four years, but is 
afterwards more rapid. The seed should be kept in 
moist sand through the winter. If sown dry in spring, 
it will not always vegetate till the next year.
