 on the southern Keys); West Indies and Mexico. 



Note on nomenclature. — Formerly designated as Trema micrantha Chap- 

 man (not Blume) and as Trema floridana Britton. The first record (1889) of 

 this plant's occurrence within our border characterizes it as a shrub, which is its 

 usual form. Under the name Trema floridana Britton it was first described in 

 1903 as a tree in Florida. According to J. K. Small (in letter of September 13, 

 1923) Trema lamarckiana (Roemer and Schultes) Blume, occurring naturally on 

 the Bahamas, Cuba, and Santo Domingo to Montserrat and Guadaloupe, has 

 been found in southern Florida.
