Ord. XLIIL VACCINIACE.E. — The Cranberry 

 Family 



Small shrubby plants, inhabiting temjjerate regions, especially 

 mountainous and marshy districts. Leaves scattered, simple, often 

 evergreen ; calyx superior, of 4 — 6 lobes, which are sometimes so 

 small as to be scarcely perceptible ; corolla 4 — 6-lobed, urceolate, 

 bell-shaped or rotate; stamens 8 — 12, free, epigynous ; anthers 

 opening by 2 terminal pores, and often furnished with 2 bristle- 

 like appendages which act as levers in the process of insect- 

 pollination ; ovary 4 — lo-chambered, surmounted by a flat disk; 

 style simple ; fruit a true berry, juicy ; seeds small, many in each 

 chamber of the ovary. By some botanists these plants are placed 

 in the same Order as the Heaths, from which they differ chiefly 

 in having an inferior ovary. The leaves and bark are astringent, 

 the berries slightly acid and agreeable to the taste. Cranberries, 

 the fruit of Schollera Oxycbccus and S. macrocdrpus, are largely 

 imported, the former from Russia, the latter from Chicago, for 

 making tarts. Several members of the Order are cultivated for 

 their j^retty flowers. 



I. Vaccinium (Whortleberry). — Low shrubs with scattered, 

 often evergreen, leaves; calyx superior, 4 — 5-lobed, sometimes 

 with the lobes so short as to be scarcely perceptible ; corolla cam- 

 panulate or urceolate, 4 — 5-fid; stamens 8 — 10; anther- chambers
