I got this from a widow and the plant - according to her at the time - is at least 50 years old. ( btw, this was 4 years ago )
This may be a red herring but she told me her husband got it in China, sold to him by someone on the side of the road when they were missionaries.
It looks as if it may be a sequential paph too. Flower is smallish. I had a look on paphs.net and didn't find anything that resembles this.
Stem is clipped as not strong enough to hold the bloom upright.
Any ideas ?
