Love these.

Nice one not often seen in collections. Probably considered by most non-Paph. growers to be one of the less attractive Paphs. but it has its charm.

I don't know if this is bullenianum or amabile. I have an amabile ' silver leaf '. Foliage is sort-of variegated. Is yours?

Here's a photo of mine. I've had 2 bloomings so far and each time the spikes we're around 12 inches tall. As per IOSPE for bullenianum. Your spike is much shorter. Foliage colour appears the same.
Irrespective of the correct name, mine grows well in my conditions.
