Paphiopedilum platyphyllum was originally thought to be a variety of Paphiopedilum stonei. It was later separated and described as a separate species. According to Dr. Koopowitz there is still some discussion among taxonomists as to its status (Orchid Digest, Oct/Nov/Dec 2019).
Regardless of its status, the plant produces magnificent spikes with up to 6 impressive flowers. It is still fairly uncommon in the hobby as it was originally known from a very small collection of plants.
This species is slow to establish when small but becomes a robust grower once it gets close to blooming size. It is easy to grow and flower. Just follow our guidelines here and you will be very successful.
