STUDIES OF TREES IN WINTER 



from Pennsylvania south and west. There are 

 thornless varieties of this tree which are often 

 cultivated. 



Yellowwood A small tree, 20 to 50 feet high, 

 ciadrastis lutea with a smooth dark gray bark, 

 The stems are smooth and brown, with light 

 colored conspicuous leaf-scars in a circle around 

 the subpetiolar buds. The buds are brown and 

 very hairy, each scale being covered with soft 

 brown hairs. Pod-like fruit, about two inches 

 long. 



The clean, smooth bark of the yellowwood, 

 its delicate branches and rich brown stems 

 make this tree attractive in winter, in spite of 

 the fact that, like the locust, its greatest beauty 

 is in its sweet pendulous flowers and bright 

 green leaves. The yellowwood is one of the 

 few trees which have subpetiolar buds, and the 

 prominent leaf-scars encircling the bud show 

 that the base of the leafstalk covered it until 

 the leaf fell off in the autumn. 



The wood is used for making gunstocks and 

 for fuel, and it also yields a yellow dye, from 

 which it takes its specific name, lutea, yellow. 

 The generic name, Ciadrastis, comes from two 

 Greek words meaning brittle branches, and 

 was given to the tree on account of its fragile 

 branches, which are easily broken by the
