Have you heard of the relatively rare aroid known as Philodendron mayoi? Despite the fact that it grows a lot in the wild, the demand for it for commercial purposes greatly outweighs the availability! It is simple to understand why collectors are pleased to add this distinctive beauty to their indoor plant collection with its broad, scarlet underbelly that mimics palm fronds. The leaf blades of this tropical plant are around 18 cm (7 inches) long. Dr. Simon Mayo, an expert in aroid botany, was recognized with the name Philodendron mayoi. It was assumed that it had been found during a study trip to Manaus in the 1940s. Some adult specimens were discovered there. Although biodiversity information systems have not yet verified this.
