Bizarrely, the description is correct. Clusterspades do not have a scientific name. How about "Clustus innominatam" (unnamed) or "Clustus sinenomine" (nameless)?
The description is small. It can be approved as it is, but I think it would be improved if you added a little more detail. Can any herbivores get through its defenses? What are its sunlight requirements? Does it grow densely, or sparsely? What does its nectar taste like?
