This new subspecies has been named for Professor 
Richard Evans Schultes of Harvard University, co- 
collector of the type and long-time student of the Ama- 
zonian flora. His protound interest in hallucinogenic 
plants is appropriately commemorated by this beautiful 
shrub which is now known to be employed extensively by 
tribes of the upper Amazon to prepare vision-producing 
drinks. 
Brunfelsia grandiflora subsp. Schultesu has long been 
recognized in the literature under a variety of misapphed 
names, including B. bonodora (Vell.) Macbride, 2B. lati 
folia (Pohl) Benth., and B. maritima Benth. It is now 
clear that these epithets all apply to other species which 
occur only as local endemics in southeastern Brazil. ‘This 
new concept is very closely related to B. grandiflora 
I). Don. and must be considered its subspecies. 
Subspecies Schu/test/ is wide-ranging and polymorphic, 
occurring in western South America from Venezuela 
south to Bolivia. In addition, an anomalous population 
is known from ‘Territory of Amapa in northern Brazil. 
It grows commonly as an understory shrub in primary 
and secondary forests between 100 and 900 m. elevation. 
Since this subspecies is widely cultivated for medicinal 
and ornamental purposes, some activity of man has un- 
doubtedly influenced its present distribution.
