STYRACACEAE. 



HALESIA. Silver Bell. 

 (Family Styracaceae). 



Shrubs or small trees, or in the 

 mountains of Tennessee large 

 trees, with shredding bark: de- 

 ciduous. Wood brownish, dif- 

 fused- porous with very fine 

 medullary rays. Twigs m o d- 

 erate, at first stellate-scurfy, te- 

 rete: pith rather small, round, 

 finally chambered, white. Buds 

 moderate, superposed, ovoid, with 

 about 4 fleshy red scales. Leaf- 

 scars alternate, somewhat raised, 

 moderate, half-round, notched: 

 bundle-trace 1, crescent-shaped, 

 compound: stipule-scars lacking. 

 (Mohrodendron) . 



The woody fruits are frequent- 

 ly persistent well into the winter. 

 When present they are character- 

 istic of the species, 4-winged in 

 H. Carolina, and 2-winged in H. 

 diptera, which is not easily differentiated otherwise.

The scaly trunk of a very large tree of Halesia Carolina 

 or Mohrodendron carolinum is pictured in connection with an 

 account of the silver bells as timber trees (p. 601) in an in- 

 structive book on American Forest Trees, which consists sub- 

 stantially of articles published between 1905 and 1913 in the 

 journal Hardwood Record, by Henry H. Gibson. 

 Glabrate: buds acute, slightly stalked. (1). H. Carolina. 



Puberulent: buds obtuse: pith less chambered. (2). H. diptera.
