I found this plant on the floor of a rainforest in southern Costa Rica in July. I would greatly appreciate any ideas on its id. Many thanks in anticipation
Gesneriaceae I believe. And most likely this one: http://www.genera-gesneriaceae.at/genera/gasteranthus.htm Welcome to the forum !
Thanks a lot Tyrlych! I am fairly certain that you are spot on with Gasteranthus delphinioides. That's a new genus for me. Thanks, also, for your welcome. Best wishes.
