This is Wild Coffee (Psychotria nervosa).

This plant is native to Florida. The pics show a small specimen but it can grow to ten feet or more. It's utilized by birds and butterflies, but according to the University of Florida "wild coffee is not recommended for human consumption." It has been used as a coffee substitute, but apparently it's not very palatable. And it doesn't contain caffeine. One source said that it was used by Native Americans for medicinal and ceremonial purposes.
