324 , WEEDS AND USEFUL PLANTS. 



Stamens 2-8, filaments somewhat united below, beneath a scale-like 

 bract with a pair of bractlets. PISTILLATE FL. in small ovoid aments, 

 Ovary with 3 scales at its base and 2 thread-like stigmas. Fruit a 

 small globular nut covered with wax-like grains. Leaves deciduous or 

 evergreen, more or less serrate. 



1. M. cerif era, L. Leaves oblong-lanceolate, toothed towards the apex 

 or entire, shining and resinous dotted on both sides ; sterile aments 

 loose, the bracts naked ; fruit spherical, distinct. 

 WAX-BEARING MYRICA. Bayberry. Wax-myrtle. 



Shrub 3-8 feet high, much branched. Leaves 2-4 inches long and from > an inch to 

 nearly an inch wide, pubescent underneath. Flowers appearing before the leaves arc 

 fully expanded. Sterile aments about * an inch long. Nuts about the size of a pepper-corn 

 encrusted with a whitish dry wax. 



Sandy soil : along the Sea-coast and Lake Erie. FL May. Fr. Aug. - Sept. 



Obs. The foliage of this shrub is, when bruised, pleasantly fragrant. 

 In New England the wax which invests the berries is collected in con- 

 siderable quantities ; it is obtained by boiling the berries in water, 

 when the wax melts and rises to the surface. Under the name of Bay- 

 berry Tallow it is often used, in the rural districts at the east, to make 

 candles either alone or mixed with tallow ; it is also employed in soap- 

 making, and great quantities are consumed for an apparently insignificant 

 use, the stiffening of the ends of circular or solar lamp wicks. An- 

 other species, the Sweet Gale (M. Gale, L.), is also found along the 

 borders of ponds, but is has no important uses. Compto'nia aspleni- 

 fo'lia, Ait., the Sweet Fern well known for its fern-like foliage and 

 aromatic odor, belongs to this order. An infusion of the leaves is of 

 reputed value in dysentery, and the dried leaves afford material for 

 juvenile cigars.
