Initially, I considered this plant to be a dark form of B. caobangensis ("U555"). It is VERY like it in many ways. However, this plant does not at all bear the winged petiole that is a characteristic of B. caobangensis. It was recently suggested (not yet confirmed) that this might be a dark red form of B. hatacoa (pers. comm , 2015, Dr. Ching-I Peng).
This plant forma 5-7" lancelate and fairly leathery leaves. It's leaf color is a deep glossy purple-green while the underside is tinted an intense wine red. My plant originated from within a packet of seed of another Vietnamese species (U636). Out of that seed tray, about 4 of these plants grew; of them, this particular plant seemed to have the darkest leaf color.
Whatever this plant is, it seems to be an easy plant for warm, humid, well-drained conditions.
These are leaf-propagated plants - currently in 3" pots.
