36 ELEMENTS OF BOTANY. 



Division III. 



GAMOPBTALOUS PLANTS. PLOWBBS WITH THE PETALS MOBT; 

 OE LESS UNITED TO BACH OTHER. (iN A PEW THE 



PETALS ARE SEPARATE.) 



ERICACEiE, HEATH FAMILY. 



Usually shrubs or slightly shrubby plants. Leaves simple, 

 generally alternate. Corolla commonly regular, 4-6-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. eesinosa), Common Huckleberry. 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. fuoxdosa), Dangleberry. A slender-branched shrub, 

 3 ft. or moi'e in height, with oblong-obovate leaves, very pale beneath,
