MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [ Vot. 8, No. 1 



for correlating the analyses of Cinchona barks with a series of field collections 

 of herbarium materials through the medium of chemist's reports. To avoid cleri- 

 cal errors in the Quito office, a special system of numbering was developed for 

 the various small exploring parties under my direction. 



It was almost certain that errors would creep into so large a series and also 

 that seeming inconsistencies would develop. A few may be noted which already 

 have come to light and are here appended. 



643. "Valley near Portovelo." This is the valley of the Rio Amarillo. 

 700-752; 1620-1644. "Chaparral and paramo E. of El Pan." This is theParamo 



del Castillo of later collections. 

 1392. Apparently there are two collections with this number. 

 1682-I710o This material, collected in May, 1944, in the Oriente in the region 



of the Rio Pastaza while in company with Dr. W. C. Steere, was not then 



given serial numbers. It is therefore chronologically out of place in the 



serieSo 



2296-2348o In an unfortunate transcription, these numbers were dated April 26; 

 they were collected March 26. 



NOTES ON OBSCURE LOCALITIES 



In general it was my aim to locate the collections while in the field so that 

 anyone wishing to find them on a map (or perhaps revisit the area) might do so 

 with ease. To this end the American Geographical Society made me a special fold- 

 ing field map, assembled from various sheets of their usually excellent map of 

 Hispanic America, 1 : 1,000,000 scale, the Provisional Edition, then current. This 

 was my constant field companion for a year and a half and is beside me as I write 

 these notes. This provisional edition doubtless soon will be revised. However, 

 its scale was such that, on occasion, it was necessary to use local maps with 

 more detail. Lacking these, as in our work in the Oriente, it was requested by the 

 office of the Mi si on de Cinchona that we prepare such reconnaissance maps as 

 would be needed for possible future worko These were necessarily sketchy, since 

 we had no proper instruments for traverse work. However, the map of this report, 

 split through the center, has been taken from a larger map prepared and delivered 

 to the Quito office on January 1, 1945. It is, so far as I am aware, the most de- 

 tailed chart of this part of the Oriente yet published. The major parts of this map 

 were put together from the notes and field sketches compiled by Mr» Jorgensen 

 and myself with, of course, such local information as we deemed reliable. Ade- 

 quate indications of latitude and longitude have been omitted; key points will 

 serve t3 orient any user of these charts when correlated with a standard map. 



The permanent labels for the specimens were printed on my return from Ecua- 

 dor. Where the numbers of specimens warranted, the localities were printed di- 

 rectly on the labels, leaving only the field data of each collection to be added. In 

 doing this every attempt was made to include such information as would serve to 

 locate some of the more obscure places not appearing on the American Geographi- 

 cal Society's maps, by reference to some well known and easily located place. 

 This was not always possible. Therefore for the sake of those desiring as nearly 

 exact localities as possible for mapping purposes, a list of those which I deemed 

 might give most trouble has been compiled. Where the Society's map is referred to 

 in the list, it is abbreviated as "the l/m map." 



In the Oriente, transliteration of Jivaro place names gave considerable trouble. 

 I am not a student of linguistics, and it was only after the printing of the labels 

 that I had opportunity to examine in any detail the work of Po Juan Ghinassi—
