Seedling material taken from Hacienda Amalia, Ecuador to Marper Estate by Pound in 1937. According to Pound (Bartley, pers.comm.) the most outstanding trees encountered [LOC79A].

Pound, 1943b [POU43B]. Progeny collected from two trees Amalia No.1 and Amalia No. 2.

Bartley, 1997d [BAR97D] There is a great deal of confusion in the interpretation of the numerical part of the name as given by Pound. In a report by Pound on the establishment of this material at Marper Farm in Trinidad he gives the numbers of progenies "observed" (although not necessarily all those that were planted) as Amalia 1 - 69 progenies observed, Amalia 2 - 67 progeny observed.
