This is another NOID Marcgravia out of Ecuador, that resembles M. umbellata. It is one of the most strikingly patterned aff. umbellatas that I have seen, and it seems to be an easy keeper so far. The new grown comes out more yellow and darkens with age.
This Ecuador native is an excellent easier Marcgravia with lots of color. New growth and somewhat new growth has bright silvery-white leaf venation and pink-red underlying foliage. More mature growth retains the red tint but is overwhelmingly that minty-green as shown below.
This distinctively marked Marcgravia (no pun intended) is from Ecuador and seems to be one of the easier species to grow, and is rather quick once established. The intense white leaf venation gets more dramatic as the plant matures, with new foliage looking rather bland in comparison. The maroon stem offers a nice contrast.
