BAYBERRY FAMILY. 
Shrubs or trees with alternate, mostly coriaceous and aromatic simple leaves 
and small monoecious or dioecious flowers, in linear, oblong or globular bracted 
aments. Flowers solitary in the axils of the bracts. Perianth none. Staminate 
flower with 2-16 (usually 4-8) stamens inserted on the receptacle; filaments 
short, distinct or somewhat united; anthers ovate, 2-celled, the sacs longitudin- 
ally dehiscent. Pistillate flowers with a solitary 1-celled ovary, subtended by 
2-8 bractlets; ovule solitary, orthotropous; style very short; stigmas 2, linear. 
Fruit a small oblong or globose drupe or nut, the exocarp often waxy. Seed 
erect. Endosperm none. Cotyledons plano-convex. Radicle very short. 
Two genera and 35 species of wide geographic distribution. 
Ovary subtended by 2-4 bractlets; leaves serrate or entire, exstipulate. 1. Myrica. 
Ovary subtended by 8 linear persistent bractlets; leaves pinnatifid, stipulate. 2. Comptonia. 
1. MYRICA LI, Sp. Pl. 1024. 1753. 
Shrubs or small trees with entire, dentate or lobed, mostly resinous-dotted leaves, our 
species usually dioecious. Staminate aments oblong or narrowly cylindric, expanding be- 
fore or with the leaves. Stamens 4-8. Pistillate aments ovoid or subglobose; ovary sub- 
tended by 2-4, mostly short, deciduous or persistent bractlets. Drupe globose or ovoid, its 
exocarp waxy. [Ancient Greek name of the Tamarisk. ] 
Besides the following species, another occurs in the Southern States and 2 on the Pacific coast. 
Bractlets of pistillate aments persistent, clasping the drupes; low bog shrub. 1. JZ. Gale. 
Bractlets of pistillate aments deciduous, the ripe drupes separated. 
Slender tree; leaves mostly acute, narrow; drupe less than 1'' in diameter. 2. WZ. cerifera. 
Shrub; leaves mostly obtuse, broader; drupe 1'’-1's’' in diameter. 3. M. Carolinensis. 
1. Myrica Gale 1, Sweet Gale. (Fig.1159.) 
Myrica Gale ¥,. Sp. Pl. 1024. 1753. 
A shrub, usually strictly dioecious, the twigs dark 
brown. Leaves oblanceolate, obtuse and dentate at 
the apex, narrowed to a cuneate entire base, short- 
petioled, dark green and glabrous above, pale and 
puberulent or glabrous beneath, 1/-214’ long, 5//— 
1o’’ wide, unfolding after the aments; staminate 
aments linear-oblong, 6//-10’’ long, crowded; pis- 
tillate aments oyoid-oblong, obtuse, about 4’ long 
and 2’ in diameter in fruit, their bracts imbricated; 
drupe resinous-waxy, not longer than the 2 ovate 
persistent bractlets, which clasp it on each side and 
are adnate to its base. 
In swamps and along ponds and streams, Newfound- 
land to Alaska, southern New York, Virginia, Michigan 
and Washington. Alsoin Europe and Asia. Ascends 
to 3000 ft, in the Adirondacks. April-May.
