Such is this taxonomic mess that I've seen vendors using Grande to refer to longifolium x humboldtii and longifolium x caudatum crosses. Then there are people still using caudatum as a synonym for humboldtii. So the answer is make a new tag if you want or leave as.
The likely accurate description is a Wossner Super Grande.
