General Comments:

Grows well well north of its native range. Documented in very southern counties with an outlier in Martin County -- that outlier is also unique in that it was collected near a cypress dome. Closely related to corn, this species has been crossed with maize to produce a corn that is resistant to Helminthosporium turcicum, the fungus that causes northern leaf blight (Wikipedia). Listed as Threatened in Florida.
