Actually, for A. cacatuoides is a bit low. A. cacatuoides is found from
Pucallpa, Peru throughout the Rio Ucayali, all the way up to Iquitos and,=

perhaps, as far north as the Rio Putumayo. The Ucayali is an alkaline riv=

with a pH of approximately 7.6. We collected A. cacatuoides along the

A. cacatuoides is probably the most high-pH tolerant species of the genus=
