Colubrina asiatica is frequently found growing in coastal hammocks and beaches from Martin county to the southern peninsula of Florida. Latherleaf is native to the Old World but escaped from cultivation. It blooms all year (Wunderlin 2003).
Glabrous, evergreen, scrambling shrub with diffuse, slender branches to 5 m (16 ft) long; in older plants, stems to 15 m (49 ft) long.
Alternate, with slender petioles to 2 cm (0.75 in) long; blades oval, shiny dark green above, 4–9 cm (1.6–3.5 in) long and 2.5–5 cm (1–2 in) wide, with toothed margins and producing a thin lather when crushed and rubbed in water.
Small, greenish white, in short branched few-flowered clusters at leaf axils; each with a nectar disc, 5 sepals, 5 hooded petals, and 5 stamens.
A globose capsule, green and fleshy at first and turning brown upon drying, about 8 mm (0.33 in) wide, with 3 grayish seeds.
Forms a thick mat, growing over and shading out native vegetation. Invades marly coastal ridges, tropical hammocks, buttonwood and mangrove forests, tidal marshes and disturbed coastal roadsides. Threatens a number of rare, listed native plant species. FLEPPC Category I
