anthers stuck together, and the manner of their 

 opening, which is always by a pore or round 

 hole, in the upper extremity of each cell. The 

 filaments, also, in all the genera, except Vaccinum 

 and Oxycoccus, grow from beneath the seed- 

 vessel, being generally slightly attached to the 

 base of the corolla. There is always a single 

 style with an undivided stigma, though the cap- 

 sule has generally four ceils, each containing 

 several of the seeds, which are small and nume- 

 rous. The calyx is four or five cleft, and the 

 corolla is tubular, with a larger or smaller limb, 

 which is also four or five cleft. The order has 

 been divided into four tribes, which I shall 

 describe in this chapter, though some of these 

 are considered as separate orders by Dr. Lind- 

 ley and other botanists. 



TRIBE I.— ERICE^. 



This tribe, which comprehends all the heath- 

 like plants, has 

 been re-divided 

 into two sub - 

 tribes, one con- 

 taining the ge-

 allied to the 

 heaths, and the 

 other those be-
