This region is very poorly known and is rich in endemic 
or restricted species, as is indicated by the classic collec- 
tions of Von Martius from La Pedrera. 
Mayna integrifolia has since been collected by Dr. 
Ducke on the Upper Amazon River (Solimées) at Sao 
Paulo Olivenga, near the Colombian border. I have ex- 
amined three excellent collections (Ducke 387, 405, 
24013) which are unquestionably referable to this con- 
cept.
