History of botanics in Samoa
Whistler, W. A. (1984). Annotated list of Samoan plant names. Economic Botany, 38(4), 464-487.

The first significant botanical work carried out in Samoa was done by the United States Exploring Expedition in 1839; although the expedition's naturalists made large plant collections, apparently no Samoan names were recorded. During the next half-century, several other large collections were made, mainly by 3 amateur European botanists--E. Graeffe, a Swiss physician, T. Powell, an English missionary, and J. Whitmee, also an English missionary. Of the three, apparently only Powell recorded Samoan names for the plants. In 1868, he published an extensive list which remains one of the best sources for Samoan plant names, not only because of its antiquity, but also because Powell was a meticulous naturalist who spoke Samoan.
A second phase of botany in Samoa was characterized by the activities of professional European botanists. In 1898, F. Reinecke published the first flora of Samoa, based upon his field work of a few years earlier. Reinecke's flora includes many vernacular names, apparently based primarily on his own work. Several years later, in his monumental book Die Samoa-Inseln, A. Kr~mer (1903), who was not a botanist, included an extensive list of Samoan plant names. These names were not, for the most part, obtained from original field work by the author, but were based primarily on the work of Reinecke, G. Pratt, and Powell. The botanical information in Pratt's Samoan dictionary (1911) was based in turn mostly upon Powell's list. Kr~imer's list is, however, valuable since new botanical identifications and clarifications were added. Four other professional botanists collected in Samoa shortly after Kr~imer and Reinecke's work--K. Rechinger, F. Vaupel, C. Lloyd, and B. Hochreutiner--but they recorded few Samoan names.
