Hello...Its a very nice paph, but I am not sure its insigne "sanderae" it looks more likely that it could be a hybrid with it...The insigne sanderae has more narrow leaves and longer and flower has not this big broad dorsal...I have visited the Island Madeira in the Atlantic ocean since 1988 where they have a large flower market where the flower ladies has various tropical plants and Orchids available, among them Paphiopedilum insigne, both regular and the sanderae variety that they grow in large beds up in the mountains where it is a bit cooler and more moist, and they are quite often seen around in the gardens here and in houses as the climate is very suitable, so I have seen many of them and had a few myself through the years, and they do not look like this one here, it is a nice one and definitely has the insigne sanderae in it but I am certain its not the species...I Will try and find photos of it from travels down there and plant of my own to post
