I learned from a knowledgeable source a few years ago that
Cat Palm (Chamaedorea cataractarum) is a clump forming palm; new plants will sprout from the base of the mother plant. It requires high indoor light conditions and high humidity whereas the
Parlor Palm (Chamaedorea elegans) has a single trunk, prefers bright indirect light and some humidity but will do okay with lower light and humidity conditions. The Parlor Palm (C. elegans) is often sold with a few to many small plants potted together.
