There is nothing 'lowly' about Maudiae type hybrids. I know there is not much of a following on the forum, but I for one love them and recognise the value that they represent as a very attractive pot plant. For the pot plant industry they are fantastic. Fast to mature (flower about 14-18 months from flask, and faster), attractive foliage, ease of culture and happy in the general home environment, large bloom relative to size of plant, and very importantly the blooms last in a perfect state for a long time.
As a group they have been extensively hybridised and 'inter-crossed', which makes them difficult to tell apart. Supersuk x Raisin Pie is called Hsinying Alien. It has the species sukhakulii on both sides of its family tree, which in most cases would lead us to expect heavy spotting of the petals, as well as quite acute petal tips. That is not to say that other forms do not occur, but my suspicion is that the label may be incorrect (may be). My initial impression was that purpuratum features in its parentage.
It does have lovely colour and appealing shape, and I am sure it will give you months of pleasure on its current blooming, and then grow well as an indoor plant and rebloom again next year! Nice purchase.
