Columnea filifera

Growing in nature in Ecuador

This species has the large leaves with the "stained glass" panes of some members of the Dalbergaria group, but the fimbriate calyces of members of the Trichantha group.   However, I can find no reference as to taxonomic location.  A closeup  of the flowers shows the unusual form of the  calyx and corolla.
