Discussion

Bischofia javanica is invasive from southern Florida to Pinellas County; it is cultivated sporadically north to Alachua County.

Once promoted as a fast-growing ornamental and street tree, Bischofia javanica frequently colonizes cultivated ground, sprouting among shrubs and hedges; it also invades natural areas. In addition to its potential to displace native vegetation in Florida, B. javanica serves as host to a variety of destructive leaf spot diseases and insect pests, especially scales (J. F. Morton 1984). Pouchlike domatia inhabited by mites can sometimes be found in the angles of major veins on abaxial leaf surfaces (S. A. Rozario 1995). Bischofia javanica is also cultivated in southern California, where it has shown no invasive tendencies.
