7 STYRACACEAE. 
HatesiA. 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 mod- 
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. 
Winter-character references:—Halesia carolina (H. te- 
traptera). Schneider, f. 87. H. corymbosa. Shirasawa, 233, 
pl. 1. H. hispida. Shirasawa, 233, pl. 1. 
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.
