Bahama Mimosa, Mimosa bahamensis, is known in Maya as Sak-Catzin, catzin being a general name for certain acacias, and sak meaning white, probably referring to the tree's abundant white flower heads, so the Maya think of it as "White Acacia." The species is a small tree very common along roadsides and recently abandoned fields. In other words, it's an almost weedy species. It seldom grows more than 15 feet tall (4.5m). That's its flowers and fruits below.
Bahama Mimosa looks like several other acacia species, except for its fairly distinctive legumes with their brownish, papery, jagged "wings" along both sides of the flat pods' faces.
The local folks more or less ignore this plant, thinking that it's too small to cut for firewood and not knowing any particular medicinal value for it, though some I've spoken to have a vague notion about its once being used as baby medicine. Its abundant flowers do feed untold numbers of nectar- and pollen-seeking invertebrates, which in turn feed birds, which perform many services in the scrub. Also, it's among the first woody plants to invade abandoned fields, so, ecologically, it's a pioneer species, and Bahama Mimosa is a good citizen after all.
