Yeah ... I can only guess ... tranlieanum x spicerianum ... the vendor was a little vague. However, it might not have any spicerianum at all and just be code for tranlieanum x barbigerum. Although some vendors here in Europe openly sell tranlieanum, coccineum, helenae and their hybrids some in the UK are still nervous about this.

I can agree with Eric.
In Europe only one hybrid with tranlienianum was known: Paph. Vinci the cross between Paph. helenae and Paph. tranlienianum
For most of the hybridizer Paph. tranlienianum looks not attractive enough. I think there would be a potential especially for compact growing slipperhybrids for the windowsill.
