 long, J'-i' wide; racemes solitary or clustered; 

 flowers appearing with or before the leaves ; calyx 

 2-bracteolate at the base, the bractlets firm, per- 

 sistent; sepals much imbricated; pedicels about i" 

 long, jointed with the rachis; corolla nearly cylin- 

 dric, 3"-4" long; anther-sacs 2-awned; style 

 slender ; stigma capitate ; capsule slightly grooved, 

 ij" in diameter, about equalling the sepals or a 

 little longer ; seeds smooth, wingless^. 



In swamps and moist thickets, Massachusetts to 

 Pennsylvania, Tennessee, Florida and Louisiana, 

 mostly near the coast. White ozier or pepper-bush. 

 April-June. 



Leucothoe elongata Small, of the Southern States, 

 is of this genus, differing from the preceding species 

 in its relatively longer sepals ; it is recorded as far 

 north as Virginia.

 Corolla globose-urceolate, 5-toothed, the teeth recurved'. Stamens 10, included; filaments 

 bearded ; anthers attached to the filaments at about the middle, ovate, obtuse, the sacs opening 

 by large terminal pores, each with an ascending awn. Disk lO-lobed. Ovary s-celled ; style 

 columnar; stigma simple; ovules numerous. Capsule subglobose, S-angled, loculicidally
