HERBARIUM RESEARCH AND FIELD WorK 
By Henry K. SvENSON 
Much of the time spent in research during the past year has 
been devoted toward preparation of a report on the relationship 
of the vegetation of the Galapagos Islands and that of the adjacent 
coast of South America. Opportunities for visiting this area were 
provided by the John Simon Guggenheim Memorial Foundation 
in 1941 and the detailed report will be accompanied by illustra- 
tions drawn by Miss Purdy. The United States National Her- 
barium and the Gray Herbarium of Harvard University have 
large collections from areas adjacent to those which I investigated, 
and their cooperation with me during visits and in the loan of 
herbarium material has been greatly appreciated. Part of the 
area in which I collected 1s now the site of the United States 
military base. It was most fortunate that this area could have 
been collected over botanically previous to the changes, which theo- 
retically at least would involve the destruction of part of the 
vegetation and the influx of many species from the outside. Some 
of the plants which were obtained, such as Zinnia peruviana, have 
probably not been seen since the middle of the eighteenth century 
The coast in the vicinity of Guayaquil, Ecuador, has been open 
to exploration for centuries. The early Spanish explorers came 
before 1800. Since that time plants have been collected by 
various nationalities, including such interesting expeditions as the 
trench Voyage of the Bonite, during which Gaudichaud-Beaupreé 
collected; the seme of Humboldt and Bonpland (about 
1800) ; explorations of the Voyage of the Sulphur (1836-1839), 
during which plants were extensively collected . Hinds and later 
described by Bentham; the ‘round-the-world Voyage of the Swed- 
ish Frigate Eugenie (1852), during which Andersson made ex- 
tensive collections on the island of Puna in the Gulf of Guayaquil
