Family 3. MYRICACEAE Dumort. Anal. Fam. 95. 1829. 

 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 longitudi- 

 nally dehiscent. Pistillate flowers with a solitary i-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. 



i. MYRICA L. Sp. PI. 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 before 

 or with the leaves. Stamens 4-8. Pistillate aments ovoid or subglobose; ovary subtended 

 by 2-4, mostly short, deciduous or persistent bractlets. Drupe globose or ovoid, its exocarp 

 waxy. [Ancient Greek name of the Tamarisk.] Type species, Myrica Gale L. 



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. M. Gale. 



Bractlets of pistillate aments deciduous, the ripe drupes separated. 



Leaves mostly acute, narrow ; drupe less than 1" in diameter. 2. M. cerifera. 



Leaves mostly obtuse, broader; drupe i"-iJ4" in diameter. 3. M.carolinensis. 



i. Myrica Gale L. Sweet Gale. Fig. 1435. 



Myrica Gale L. Sp. PI. 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, 1-2!' long, s"-io" 

 wide, unfolding after the aments; staminate aments 

 linear-oblong, 6"-io" long, crowded; pistillate 

 aments ovoid-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 and are adnate to its base. 



In swamps and along ponds and streams, Newfound- 

 land to Alaska, southern New York, Virginia, Michigan 

 and Washington. Also in Europe and Asia. Ascends 

 to 3000 ft. in the Adirondacks. Fern or scotch-gale.
