14. LEUCOTHOE D. Don, Edinb. New Phil. Journ. 17: 159. 1834. 

 Shrubs, mostly tall, with alternate petioled entire or serrulate, in our species persistent 

 leaves, and small usually white bracted flowers in axillary racemes, the bracts persistent. 

 Sepals S, distinct, imbricated, at least in the bud. Corolla cylindric or ovoid-urceolate, 

 5-toothed. Stamens 10, included; filaments subulate; anthers attached to the filaments near 

 their bases, oblong, the sacs opening by terminal pores, obtuse, 2-mucronate, awnless. Disk 

 lo-lobed. Ovary S-cellcd; style slender ; stigma 5-lobed ; ovules niimerous. Capsule depressed-
