I have several questions about taxonomy and first an example: If i say that I grow Phragm. sp. what does that mean? Do you understand it like I'm growing one specific Phragm. species with no name or only that I grow several Phragm. species? Wouldn't it be more correct if I said that I grow Phragm. spp. (spp.= species pluralis)? In this way you'll understand that a grow 2 or more different species. If I buy a plant that is named Phragm. sp. I understand this like it's a Phragm. but it's unknown or hasn't been registrered (it's a little difficult to explain this with Phragm. as example but try to think in other genuses to). What does sspp. means?
