Discussion

Forsstroemia producta is known from only five sites in the flora area. Recent efforts to recollect it in Ohio were unsuccessful. The interval of fertilization is in late summer and autumn; growth intervals are usually defined by vegetative branches. The secondary stems are erect or somewhat curved; the leaves are imbricate; and the exostome teeth have well-defined plates and occasionally additional external depositions.
