 Anthers awned or awnless, upwardly prolonged into tubes, open- 

 ing by a terminal hole or slit of the tubular apex of each cell. 

 Ovary 4-5-celled, or 8-10-celled by false partitions ; ovules several 

 or numerous in each cell. 



§ 1 EuvACCiNiUM Gray. Leaves deciduous. Flowers on 

 drooping pedicels, solitary or 2-4 together, developing with or 

 soon after the leaves. Corolla from ovate to globular, and more 

 or less urn-shaped, 4-5-toothed. Filaments glabrous; anthers 

 2-awned on the' back, included. Ovary and berry 4-5-celled, with
