Anthurium Rotundistigmatum is known for certain from tropical wet and premontane wet forest.
The species is a member of section Belolonchium and is best characterized by its thin, ovate-triangular leaves.
They grow best in bright, indirect light. Anthurium care also requires that the soil be free draining but hold some water. If you are growing this plant as a houseplant, a half and half mix of potting soil and orchid soil or perlite will provide the kind of soil anthuriums prefer.
The plant is over 40 cm tall and will be shipped in a 12 cm pot.
