Where are you? Many years ago, it was reported that many of the so-called "barbatums" in the US were really callosum v. sublaeve (or its synonym, "thailandense"). Which your's definitely looks like. But I do admit that the floiage is closer to barbatum.....however, mottled leaf paphs have great variability in their patterns. My guess is callosum sublaeve....Take care, Eric
