Amazon, Andes, Croton abonari, C. chimboracensis, Euphorbiaceae.


Two rarely collected species of Croton from South America are des cribed and illustrated. Croton chimboracensis P.E. Berry & Riina is localized in western Andean Ecuador and is sister to Croton sect. Adenophyllum Griseb. Croton abonari Riina & P.E. Berry is known from a single location in Amazonian Brazil; it resembles both C. sampatik Müll. Arg. and members of Croton sect. Cuneati (G.L. Webster) Riina & P.E. Berry, but C. abonari can be easily distinguished from both groups by distinctive morphological characters
