"The peculiar character of the Vegetation on the Galapagos Islands was brought to scientific attention in 1847 by Sir Joseph Dalton Hooker. His flora of the archipelago, based chiefly upon the collections of Darwin, showed clearly that these islands, although small in extent, volcanic in character, and only five hundred to six hundred miles from Ecuador, possess a vegetation striking in individuality and variety very unlike that of the adjacent mainland. In 1852 Prof. N. J. Andersson, well known for his critical studies in Salix, visited the Galapagos Islands on a voyage of the Swedish frigate " Eugenie". He landed upon five of the islands, four of them being the same as those visited by Darwin, and the fifth (Indefatigable) until then entirely unknown botanically. The sailing schedule of his vessel permitted him to remain but a few hours upon some of the islands, and upon none more than two or three days. Nevertheless, he was able to secure an excellent collection of plants, including 338 numbers, many of which were represented by several specimens. These plants, critically determined by Andersson himself and distributed to the leading herbaria of various countries, have long furnished the chief reference specimens for the interesting vegetation they represent. In 1853 Andersson published a detailed flora of the islands, and in 1857 he republished the same work in revised form and well illustrated with 17 plates." (cit. B.L.
