Paphiopedilum subgenus Megastaminodium is a subgenus of the orchid genus Paphiopedilum.[1] It was erected to accommodate the single species Paphiopedilum canhii due to its distinct characteristics that made it unfit for the other subgenera. Its placement has since been backed by cytological, molecular and micromorphological evidence.[2]
