The first one is a very small one. It is P. niveum ('Winter Sun' x 'Siam Snow'). It is a first flowering seedling NS is 4.5 cm, LS is 13 cm. Thanks a lot tpaphio! The next one is a sister of the first. It is bigger and VERY round. And here is a Paph. niveum from an other source. It is less round but bigger. NS is 8.5 cm I like them all just because they are P. niveum!
