Phryma leptostachya Linnaeus. American Lopseed. Phen: May-Aug; Jul-Oct. Hab: Bottomland forests, nutrient-rich slopes, mesic hammocks, in the Coastal Plain primarily in places underlain by coquina limestone (‘marl’) and essentially absent from the more acidic portions of the Coastal Plain. Dist: QC west to MB, south to ne. FL, Panhandle FL, and TX.

ID notes: The fruits "lopped down" against the stem are unmistakable.

Origin/Endemic status: Native

Taxonomy Comments: An e. Asian relative has been variously treated as a separate species (as here), subspecies, variety, or merely form; the treatment here of the American and Asian plants as separable at species plant makes the Asian plant P. asiatica (H. Hara) O. Degener & I. Degener.
