Catclaw Blackbead - Pithecellobium unguis-catis
Ranging from northern South America throughout the West Indies, and north to southern Florida, including the Gulf Coast, this Blackbead can reach tree size in rich soils. It grows in sandy or coral substrates, on dunes, and sometimes alongside roads. The wood is hard, and the leaves are paired (two leaflets each), with short stalks. The branchlets are armed with spines at the leaf bases. The flowers have a bell-shaped calyx and tubular corolla and are borne in one-inch clusters. The pods are coiled, and the seeds are black and beadlike.
