A nice miniature (ish) Philodendron from the Sira Mountains, Peru.  This is the habitat where Ranitomeya sirensis occurs, so if you’re looking to do a biotope this would be a good one to use! It resembles one that the Ecua companies are selling as aff. undulata, but the leaves are thicker, the petioles a bit more winged, and it tends to flush pink on the petioles when in high light.

Available plants are well rooted in 4″ pots.  The last photo is representative of the size plants available.
