In no. 2 of this volume I have published, together with Dr. CHRISTENSEN, 

 a list of the ferns reported from Easter Island. While reading the proofs I 

 received from Professor B. L. ROBLNSON of Harvard University, Cambridge, 

 Mass., a complete set of the collection made by AGASSIZ and his comrades 

 during the Albatross Expedition [1904). It was then impossible to take into 

 due consideration the ferns contained in this collection. It does not extend 

 our knowledge of the fern flora; still I find it better to enumerate the species 

 found by AGASSIZ with the remarks written on his labels as an appendix to 

 this paper, especially as his collection was made before that of FUENTES. 



The latest and most complete enumeration of the flowering plants is to 

 be found in FuEXTES' >-Resena botanica sobre la Isla de Pascua (Inst. Centr. 

 Meteor, y Geofis. de Chile no. 4, 1913 and Bol. Mus. Xac. de Chile V: 2, 

 191 3). The earliest collection seems to have been made by G. FORSTER du- 

 ring Cook's second voyage: most of the plants found by FORSTER were 

 enumerated in his "Florulae insularum australium prodromus>., Gottingen 1786. 

 Some species mentioned by FORSTER in his narrative (A voyage round the 

 world, London 1771 vol. Ij do not figure in the Prodromus, as for example 

 such an important plant as Sophora (the Mimosa of FORSTER). A. v. CHAM1SSO, 

 during the voyage of KoTZEBUE (see >.Reise um die Welt. 4. Aufl., Berlin 

 1856) also collected plants on Easter Island, and has been quoted as collector 

 in a few cases. In 1836, S. ExDLICHER included all statements related to 

 Easter Island plants in his Bemerkungen tiber die Flora der Siidseeinseln 

 (Ann. des Wiener Museums der Xaturgeschichte I). HEMSLEY's list in sReport 

 on the present state of knowledge of various Insular Floras* (Report Chall- 

 enger, Bot. I p. 15, 1885) is based on Exdlicher, but Sophora tetraptaa and 

 Scsiivhivi porhtlacastnim are added. 



FuEXTES confined himself to an enumeration of what he had collected 

 on the island in 191 1; his list contains 40 indigenous or naturalized species. 

 Many of these had been found by the Albatross expedition seven years earlier,
