DescriptioTi,. 



!^:S^HE Cladrastis tinctoria, in 

 't~P 1^ favourable situations, at- 

 M, tains a height of thirty 

 ia to fifty feet, and a diame- 

 ter of ten to twelve inches. The trunk is covered 

 with a greenish bark, which is smooth, instead of 

 being furrowed, like that of most other trees. The 

 branches are brittle, and like the petioles and 

 nerves of the leaves, are of a yellowish hue. The 

 leaves on young and thrifty stocks are from a foot 

 to a foot and a half in length, and on old trees they 

 are not more than half of that size. They are 

 composed of two rows of leaflets, which are petio- 

 lulate, broadly oval, entire, smooth, the terminal 

 one rhomboid-ovate, acuminate, an inch and a 

 half to two inches broad, and from three to four 

 inches long. As in the Platanus occidentalis, (syca- 

 more,) the lower part of the common footstalk 

 contains an embryo bud, which becomes visible in removing the leaf. The flow- 

 ers, which appear in April and May, form elegant white, pendulous racemes, 

 from six to ten inches long, resembling those of the Robinia pseudacacia, 

 (locust,) but less odoriferous. The seeds are contained in flat, even pods, from 

 three to four inches long, and about one fourth of an inch wide, the margins of 

 which are often somewhat undulate by the abortion of a portion of the seeds. In 

 the United States the seeds mature in the month of August ; but in Britain, the 

 tree is seldom seen in flower, which is probably owing more to the age of thft 

 trees than to the effects of the climate. 



Geography and History. The Cladrastis tinctoria is a native of Kentucky, 

 western Tennessee, and northern Alabama, where it is sparingly produced. It 

 is successfully cultivated as an ornamental tree in many parts of the United 

 States, and is perfectly hardy as far north as Massachusetts.
