Columnea moorei is a beautiful species, with small shiny red-backed leaves and interesting pinkish-orange and yellow flowers. The succulent stems branch and twist irregularly.
A 2017 publication by Smith and collaborators has demonstrated that this rarely collected species from Panama is of hybrid origin. One parent is from section Columnea, the group with large bilabiate corollas. The other parent is unclear and may not have yet been sampled in the molecular data, but may be close to C. minor.
The plant above was shown at the 2018 Gesneriad Society convention show, and was decorative without flowers. Other photos of the species, with flowers, can be seen in a slideshow by clicking one of the links below:
