Could be a lot, most Buce in the trade have Fantasy names anyway and are yet not scientifically determined and have no officially documented botanical name. Some nurseries e.g. Dennerle are cultivating their own line now from several collected species and do no longer randomly import this plant sp. for conservational reasons.
From a lot of other sellers, taking advantage of the growing popularity, the plants are actually snatched from nature by amateur (poachers). And then it gets the name from the region it is taken from or simply a name reflecting growth characteristics.
Thus pick any name you like, that's anyway how they go in the trade. One seller might name this plant B. Sp. Pinky Curly and the next one names the same plant after the region it is found where ever that might be.
The name says all, really.
BUCEPHALANDRA....... yep, it is a Bucephalandra
SP. ......... we do not know the exact species
RED ........... it probaply is more red-ish, than anotherone, that is less red
So any species of Bucephalandra can be presented by such name .......... and actually should be, if you can't give a definite ID.
Or - like Marcel already said - you can present it by fantasy-names or origin. Such name must be surrounded by ' x '.
In this case it would be presented: Bucephalandra sp. 'red'
If you read Tropica's description of Bucephalandra sp. 'red', you will see that it actually cover several more or less different types. This is because most of the tissue culture material comes with the "fantasy names" as described, and can't really be botanically identified.
If this is the Tropica product (and it looks like it is) , you can be sure it is a comercially produced plant and not a wild collected, though.
