This is the general problem.......
Botanically every plant has its very own name. This plant - and ONLY this plant - can rightfully carry a given, botanical name. The name is given to the plant based on specifications, usually focused on flower (flowers are much less prone to change because of environment, than leaves are - therefore much safer for ID).
HOWEVER..... when we start using 'x' and "x" and the like of signs, there are very little restrictions (if any!). I am often quoted fore saying "we can call it Donald if we wish to. As long as we use these signs ' x ' ".
FURTHERMORE we are talking hybrid in this case - and finally there is usually some variation in the "lines"(especially when intense, commercial cultivation, often including TC propagation, is carried out) of a given species/hybrid/cultivar or what have we here. Botanists will decide if variation in a given plant is enough to give a new plant, a variation or just an acceptable variation within species (when and if they find the time). Kasselmann is doing a lot of this, within the plants we use for our aquaria (be thankfull for her interest!).
- my best guess is, they are all variations of the C. x willissii in the end.
