MONOECIA MONADELPHIA. 
Mich. 2. p. v 213. Sp. pi. 4. p. 588. Pursh/2. p. 60S. Nutt. 2. p. 22 6. 
A shrub 6 — *12 feet high, diffusely branching, the branches and leaves 
glabrous. Leaves scarcely an inch in length, lanceolate and oval-lanceolate, 
very acute; on petioles 2 — 3 lines long. Flowers in terminal spikes. Ste- 
rile florets towards the summit numerous. Fertile florets few at base. Ste- 
rile florets, Scale or Bractea, short, ovate, 1 — 2-flowered. Corolla 3- 
cleft. Stamen $ generally three. Filaments very short. Fertile florets. 
Scale small. Corolla 3-cleft, persistent. Styles 3, united at base, reflexed. 
Stigmas simple. Capsule 3-celled, 1 seed in each cell. 
In all of the specimens I have seen of this species, there are as usual in 
this genus 2 or 3 fertile florets at the base of each spike. 
In this genus I think the scale that surrounds each group of sterile florets 
can only be considered as a bracteal leaf, and the corolla a real calyx. 
Grows along the margin of creeks and swamps in the middle districts of 
Carolina and Georgia. 
Flowers May — July.
