36 ELEMENTS OF BOTANY. 
Division III. 
GAMOPETALOUS PLANTS. FLOWERS WITH THE PETALS MORE 
OR LESS UNITED TO EACH OTHER. (IN A FEW THE 
PETALS ARE SEPARATE.) 
ERICACEZ, HEATH FAMILY. 
Usually shrubs or shghtly shrubby plants. Leaves simple, 
generally alternate. Corolla commonly regular, 4-5-cleft, 
sometimes polypetalous. Stamens hypogynous, distinct, as 
many or twice as many as the petals, the anthers mostly 
opening by a hole at the end (Fig. 138, III). Ovary usually 
with as many cells as there are corolla-lobes; style 1. Seeds 
small, with albumen. The family is divided into several sub- 
families, of which two are here described. 
I. WHORTLEBERRY SUB-FAMILY. 
Shrubs. Calyx-tube adnate to the ovary, on which the 
gamopetalous corolla and the stamens are borne. Fruit a 
true berry, or resembling one. 
I. GAYLUSSACIA, HUCKLEBERRY. 
Calyx 5-toothed. Corolla urn-shaped or bell-shaped, 6- 
cleft or 5-toothed. Stamens 10, the anthers opening by holes 
in the blunt or tapered ends of the cells. Ovary 10-celled, 
each cell containing a single ovule, the whole forming a berry- 
like, 10-seeded stone-fruit. Flowers small, white or pinkish, 
in lateral bracted racemes. Leaves and little twigs generally 
dotted over with resinous particles. 
a. (G. RESINOSA), Common HuvcKLEBERRY. A _ small, stiff- 
branched shrub, 1-3 ft. high, with oval leaves, and short, one-sided 
racemes of somewhat cylindrical flowers ; fruit black with no bloom, 
sweet, commonly gathered for sale. 
b. (G. FRONDOSA), DANGLEBERRY. A slender-branched shrub, 
3 ft. or more in height, with oblong-obovate leaves, very pale beneath,
