Did you know?
The top of the anthers open like the lid of the box to release the pollen and this character gives the plant its genus name composed of the Greek pyxis, little box, and anthera, Latin for anther (Fernald 1950).

State Ranking Justification [-]
There are two existing populations but one of them is very small. There are no other known historical populations.
