LXIV. ERICACEAE, HEATH FAMILY. 



A very large family, of shrubs, herbs, or even small trees, 

 difficult to define as a whole ; the leaves are simple and mostly 

 alternate (sometimes reduced to white or colored scales) ; the 

 flowers almost all regular, and with as many or twice as many 

 stamens as there are petals or lobes of the corolla; their 

 anthers 2-celled, each cell more commonly opening by a pore 

 or hole at the end ; ovary mostly with as many cells as there 

 are lobes to the corolla ; style only one, and seeds small. The 

 HEATH and HEATHEB (the former cult, in some greenhouses 

 in several species, and the latter sparingly wild E.) belong to 

 this family, and are distinguished by small or needle-like ever- 

 green leaves, the corolla becoming dry and persisting, its lobes, 

 and those of the calyx, 4 ; stamens 8. 



I. WHORTLEBEEEY SUBFAMILY, known by having 

 the tube of the calyx adherent to the ovary, on which the 

 monopetalous corolla and the stamens are therefore mounted. 

 All are shrubs, with scaly buds. Fruit a berry or berry-like. 



1. GAYLUSSACIA. Stamens 10 ; anthers with the cells opening by a chink at the blunt 



or tapering top. Ovary 10-celled with one ovule in each cell, forming a berry -like 

 fruit containing 10 apparent seeds, or properly little stones. Flowe.-s in lateral ra- 

 cemes ; branchlets and leaves beset with resinous or clammy dota. 



2. VACCINIUM. Stamens 10 or 8 ; anthers tapering up into a tube with a hole at the 



top. Ovary with several or many ovules in each cell, forming a pulpy many-seeded 

 (rarely rather few-seeded) berry.
