Herrania Camargoana is named in honor of Dr. 
Felisberto Camargo, founder and director of the Insti- 
tuto Agronomico do Norte in Belém do Para, Brazil. 
Possessed of a deep patriotism and a fervent desire to 
take the benefits of agronomical science to the poor and 
forgotten caboclo of the Amazon valley, Camargo has, at 
times almost single-handedly, carried out an energetic 
crusade to improve the lot of the Amazon through better 
agriculture. In spite of discouraging odds in the form 
of tremendous distances, primitive transportation and 
actual lack of geographical knowledge of large areas; 
and of poverty, sickness, apathy and lack of education 
amongst the people themselves, the efforts of Camargo 
and his small but loyal group of scientists are beginning 
to bear real fruit. To the best of my knowledge, this 
program, embracing many phases of fundamental biolo- 
logical research (from plant exploration and introduction 
to forest tree breeding and phytopathology) and the es- 
tablishment of nurseries and plantations, constitutes the 
only sustained agricultural work of a truly scientific na- 
ture which the Amazon has seen in the four centuries 
since its discovery by Europeans. 
Restricted apparently to the uppermost Rio Negro 
basin, Herrania Camargoana seems to have as its closest
