INTRODUCTION
The present work brings together a catalog of the herbarium and seed collections of the green-fruited
species of Lycopersicon and the related Solanum pennellii. The latter is included because it behaves in all
biosystematic respects as a species of Lycopersicon. The authors have used the notes available from
herbarium sheets and collecting expeditions together with their personal experiences in the western part of
South America. The material is presented in two ways: first by species (Tables 1-4), and second, by
geographical locations (Tables 5-44). It is hoped that this will help workers to see how the available seed
represent the geographic distribution of the different species and also help future collectors to decide what
areas to explore.
Some of the more important observations and publications are mentioned, but no attempt has been
made to include reference to all the research on these species. Information about the useful characters of
the species may be obtained from North Central Plant Introduction Station, Ames, Iowa 50010, USA. The
following works have been cited:

In the second part of the catalog, the information for each watershed includes:
a. A discussion of the general characteristics of the watershed and/or specific observations of the species
found there. Special emphasis has been given to any unique features of the area or material.
b. A table with the species name, the site name, the altitude of the site (as recorded by collector), name of
the collector(s), date of collection, existence of herbarium specimen, availability of seed, population
size where original collection was taken, and identification number.
c. A map that includes several watersheds with symbols indicating the approximate location of the sites of
the species listed.
In Tables 1-4 (Part I), the following symbols denote:
PI - Plant Introduction Number of the United States Dept. of Agriculture
LA - accession number of C. M. Rick, Dept. of Vegetable Crops, Univ. of Calif., Davis
DHUNA - acc. number, Dept. de Horticultura, Universidad Nacional Agraria, Lima, Peru
H -acc. number of J. Hawkes, Dept. of Botany, Univ. of Birmingham, Birmingham, England
In Tables 5-44 (Part II) the symbols explained above are followed by the collector's number (e.g.
LA126); the other symbols designate the herbaria where specimens are housed, and in this case the
identifying number precedes the symbol (e.g. 9129 USM). With the exception of two private herbaria -- OCH
(Carlos Ochoa, International Potato Center, Apartado 5969, La Molina, Lima, Peru); R (C. M. Rick, Dept. of
Vegetable Crops, Univ. of Calif., Davis) - the symbols designate public herbaria of the world and are listed
in Index Herbariorum (see Lanjouw 1954). It should be noted that for most of the LA accessions of Rick,
unmounted herbarium species are available; also that a few of the Rick collections have SAL accession
numbers.
