Columnea minor

Also known as Trichantha minor, Columnea teuscheri and Trichantha teuscheri.

This is a variation of the species, with a very hairy corolla and a redder calyx. The corolla tube appears to be significantly shorter than in another specimen on this site. Note, however, that both have a very fimbriate (hairy) calyx.  A third version can be seen here and a fourth here.  A whole trailing plant, grown indoors, illustrates the wiry stems and lax trailing habit typical of the species.
