Buttonwood - Conocarpus erectus
Subtropical, this tall tree is locally common in the wetlands of southern Florida, often close to mangrove swamps. Mature trees are most easily identified by the brownish, scaly bark; the leaves are elliptical and pointed at the tip with two glands at the base of the blade. They are untoothed and yellowish-green, although in some cases they are clothed with silvery hairs. Tiny, greenish flowers are borne in dense, rounded heads, and consist of sepals only. The fruit is berrylike, consisting of tightly-packed drupes, with a single seed.
