vided, and in Puerto la Cruz the facilities of the company's staff house, commis- 

 sary, and warehouse have been placed at our disposal. 



Through the generosity of Mr. Mack Lake, President of the Orinoco Wining 

 Company, Mr. G. G. Lancaster has in a similar manner placed the Company's 

 facilities in Ciudad Bolivar at our disposal for the duration of the program of 

 exploration. 



Special funds, supplies and equipment have been generously donated by 

 many friends of exploration and the New York Botanical Garden. Chief among 

 these should be acknowledged the financial assistance of the Garden Club of 

 America; the contributions of trade goods, miscellaneous supplies, hunting and 

 fishing equipment by Sears F,oebuck and Company, and by the Johnson Motor Com- 

 pany a 1951 Johnson "Seahorse" twenty-five horse-power outboard motor, so es- 

 sential to travel on the ' 'highways" of the interior, Venezuela's great rivers. New 

 drugs and medicines developed within recent years have made the work of tropi- 

 cal exploration comparatively safe; Parke, Davis and Company supplied us with 

 Chloromycetin and camoquin, Charles Pfizer and Company provided terramyacin 

 and penicillin, and Squibb and Company donated penicillin and sulfadiazine. 



The forerunners in this program, Dr. G. G. H. Tate, Dr. H. A. Gleason, Dr. 

 Tobias Lasser, and the many collaborators who have contributed their talent and 

 knowledge to the earlier reports on the explorations of Roraima, Duida, Auyan- 

 tepui, Kaieteur, Tafelberg, and Yavi; Dr. Henri Pittier and his associates, Dr. 

 Tobias Lasser, Dr. Francisco Tomayo, Dr. L. Schnee, Captain Felix Cardona; 

 and Dr. Julian A. Steyermark, who has conducted independent exploration, have 

 provided a background of immeasurable consequence. And, finally, in the present 

 assessment of collections, the experienced judgment of colleagues is being 

 sought to assure the most competent understanding and interpretation of the flora 

 of Guayana that is possible at this time. The report of each contributor will ap- 

 pear over his own name.
