spontaneously produces prodigious amounts of seed. Seeds of 
the original “Kew Plant” were sent out to conservatories and 
botanical gardens throughout the world, and it is likely that 
some of them found their way to the New York Botanical 
Garden. 
In short, the specimen which Rusby collected in cultivation 
must be excluded as a type of Erythroxylum truxillense. It was 
misconstrued by Rusby as being identical with the Trujillo 
leaves of commerce. In spite of his extensive field experience 
with coca in South America dating from 1885, Rusby never 
visited Trujillo and never saw or collected Trujillo coca in the 
field. Since this plant is grown only in a limited area in South 
-America and is not cultivated in other countries, it is under- 
standable that Rusby failed to recognize the subtle differences 
between the dried leaves of commerce and the living specimen 
of E. novogranatense in the greenhouse. 
Most botanists since the time of Rusby have agreed that the 
cultivated coca plants belong to two closely related species of E. 
Coca and E. novogranatense (Schulz, 1907; Payens, 1958; Towle, 
1961; Gentner, 1972; Machado, 1972; Plowman, 1979a). Until 
recently Trujillo coca was generally included within E. novogra- 
natense. But no botanists had ever studied Trujillo coca in the 
field or had examined herbarium specimens collected in Peru. 
The only exception to this were studies of archeological coca 
leaves from coastal Peru, which certainly represent Trujillo coca 
(Harms, 1922: Griffiths, 1930; Towle, 1961; Plowman, 1979a). 
The first documented herbarium specimens of Trujillo coca 
which I have found in major herbaria are those collected by 
Augusto Weberbauer in 1914 in the Province of Pataz in Peru, 
along the upper Rio Maranon. These were originally identified 
as Erythroxylum Coca. No further specimens of Trujillo coca 
were made until the 1960’s when interested botanists began to 
sample the local varieties of coca. From these recent collections, 
it is finally possible to assess intelligently the taxonomic status of 
Trujillo coca. 
From herbarium studies, transplant experiments, chemical 
analyses and anatomical studies, it may be affirmed that Trujillo 
coca is in fact best placed in the species FE. novogranatense. 
However, it differs from the typical form of this species suffi-
