Myrica. Bayberry. Wax Myrtle. 

 (Family Myricaceae). 



Shrubs or very small trees, aro- 

 matic: deciduous in the North. 

 Twigs rounded or angular, slen- 

 der, resinous-dotted when young: 

 pith small, somewhat angled, con- 

 tinuous, green. Buds small, soli- 

 tary, sessile, subglobose or ovoid, 

 with 2 or about 4 exposed scales, 

 the end-bud absent. Leaf-scars al- 

 ternate, half-elliptical or some- 

 what 3-sided, more or less raised:

The sweetfern is considered 

 sometimes to represent a distinct 

 genus (Comptonia), of which it 

 is the only representative. A 

 readable account of its ancestry 

 is given by Berry in volume 40 of 

 The American Naturalist. The 

 sweet-gale also has been held 

 ipart under the generic name Gale.
