to be published in Chronica Botanica, Vol. 6 (1941) PLANT SCIENCE in LATIN AMERICA A timely series of articles and lists compiled by the Editors of Chronica Botanica with the aid of many Authorities in the U.S.A. and Latin American countries. AT THE present time there is a world-wide interest in the Vegetation and Natural Resources of Latin America. An extensive and up-to-date account concerning the plant sciences in Latin America seems to the Editors of Chronica Botanica to be the most appropri- ate contribution which they can make at pres- ent to the improvement of international rela- tions and cooperation in t …

-15- or (2) the periphery of the areas of cultivation, in regions nearer to the United States. I chose the second alternative for the following reasons: having little knowledge of the plants themselves, it seemed undesirable to spend time in the area of greatest diversity until techniques for studying the plants had been firmly established; another reason was, of course, financial. Brazil is more than twice as distant from the United States than the West Indies and Central America. In addition, it was necessary to have the cooperation of institutions interested in these studies to help maintain growing collection …

In Amazonia proper, we will be able to rely on the cooperation of Dr. Stéfano Varese who, as Director of the Centro de Investigaciones de Selva del Instituto Raúl Porras Barrenechea, is also conducting research among the Aguaruna. The results of our project should contribute in a complementary way to Dr. Varese's who is interested in the effects of the Peruvian Government's recent colonization plans for the jungle on its aboriginal inhabitants. Dr. Varese's aid in procuring permission from Peruvia …

… ent each other, the former being more or less indispensable for the success of the latter. Experienced collectors who have been for some years working in Peru under my direction would carry on the proposed plant exploration according to a specific plan of operation which I would prepare and which would be based on my rather long contact with the Peruvian vegetation. With its arid, semi-arid and subtropical to tropical subdivisions Peru is a quite remarkable republic vegetationally and has been the source of a number of the most commercially valuable plants and plant products. Needless to say, it would be a source …

work have been selected on the basis of long experience in South American exploration. The enclosed reprint may have some interest for you. The map on page 81 shows routes of members of the five previous botanical expeditions and indicates how extensive our South American collecting has been. Should you, at this time, feel that you would care to support my project I would appreciate it very much. From past experience I have learned that when an expedition is in the field in the highlands of South America unanticipated financial problems arise. Any addition to the estimated budget total for my work would, therefor …

… Mr. Richard S. Rheem 801 Chesley Avenue Richmond, California Dear Mr. Rheem: Last April Mr. Marshall P. Madison wrote you concerning his interest in and proposed support of a projected continuation of the South American plant exploration carried on, under my direction, during the past twenty years by this Botanical Garden. At that time you indicated to Mr. Madison that should the project materialize you might care to aid in its financing. Therefore, he has suggested that I report to you on its present status. As a result of Mr. Madison's generosity and that of certain of his friends and of grants-in-aid made by …

2. Extensive collecting of other Euphorbiaceae, especially members of subfamily Crotonoideae Pax, for systematic studies. 3. The obtaining of propagules of Cnidoscolus for dispersal to botanical gardens or to other cultural institutions and specialists concerned with possible economic uses. 4. The training with field experience in tropical and subtropical vegetation for graduate students. TRAVEL South American field work will involve two trips, one of a two-month and one of a four-month duration by the principal investigator and a graduate student research assistant. The areas to be visited will be primarily type …

… 1954 Mr. Stanley Powell California Packing Corp. 215 Fremont San Francisco, California Dear Stanley: Referring to our recent conversation, I am anxious to determine whether my knowledge of and contacts in South America over the past almost twenty years may not be put to some use in connection with projects of international import and particularly those emphasizing increase of mutual understanding and goodwill between the two Americas. I have gone to South America six times since 1935 to direct botanical expeditions from U.C. (Berkeley) which have surveyed the character and distribution of the vegetation, princip …

to give large sums of money with no strings of any sort attached. I might say that I have directed four successful plant explorations primarily on the West Coast of South America and have personally worked down there for a total of over four years in the last twelve years. Much of this time has been spent in Peru which our expeditions have covered quite thoroughly. Continuation of Woytkowski's collecting, therefore, will be based upon a large accumulation of information as to the most potentially important areas to be worked. It would seem to me that the American Orchid Society might care to support a project whi …

Project -- Evaluation and clarification of phytogeographic problems in temperate South America, 1957-59, T. H. Goodspeed The following specific research projects are derived from long contact with the floras of temperate South America, their character and distribution (cf. p. 1). The particular areas involved in each case appear to be critical, in terms of geologic history, for evaluation of postulates concerning trans- and inter-Andean plant distribution and the origin and evolution of the vegetation they now exhibit. I. Factors influencing trans- and inter-Andean plant distribution Peru (1) In 1942-43 some coll …

a Director of the Botanical Garden and someone to handle my courses. We are off to South America for the 7th time in September. I have gotten hold of some money and the Guggenheim Foundation has given me another Fellowship and so there will be another plant hunting expedition in the "other America." We will be away, with a party of collectors, until March 1958 and then put in a year here working on the collections. My very best to you and the Senora. As ever yours, THG:T

… Dear Walter: I am sorry that your letter of April 15 has so long remained unanswered. Your account of your recent year's collection sounds as though you certainly have kept up your enthusiasm for acquiring plants. I hope that you keep in touch with this Herbarium so far as exchanges are concerned because I am sure that they have material that would interest you. Of recent years our Herbarium has developed a good deal and has acquired a fine collection of duplicates for exchange. I have finally brought to a close the formal South American collecting after nearly twenty years of it and five trips down there. The la …

Identification of Gaps in Major Collections Support for foreign and domestic plant explorations comes from various sources, i.e. state, federal, and private funds. One account administered by the Agricultural Research Service, USDA, is used exclusively to support plant-collecting expeditions, about six per year. In 1976, for example, three foreign plant explorations and two domestic explorations were carried out. Germplasm of several species of cotton was collected in remote areas of Honduras, Nicaragua, and Mexico. Ecological data were also gathered on the boll weevil and other cotton insects. Primitive tomato v …

the three countries -- i.e., visit Argentina between January 15 and March 15. On the 1957-58 expedition the objective will be research on problems of plant distribution in the Andes rather than Nicotiana collecting. In Argentina I will be particularly interested in having collections made up to the limits of vegetation in what was formerly called Prov. Los Andes, particularly near the passes over to Chile, to compare the species there with those on the Chilean side in Provs. Tarapaca and Antofagasta. This would probably mean that for a time I and my collectors would make Tucuman our headquarters. Perhaps your Ins …

The past season I had a most successful time of it in Guatemala, and brought back some 19,000 numbers of plants. With the collections planned for the coming year we should have sufficient material for a creditable account of the plants, and I hope we may begin publication by the end of next year. Already we have a good quantity of manuscript. Work in the Museum has been delayed lately because all our WPA employees were taken away July 1. In the course of time we may become accustomed to getting along without them, …
