Except the "E" can mean anything. Either spell out the genus and note it as "sp." for a single unspecified species, or "spp." for multiple unspecified species. If you abbreviate the genus, you can't use "sp." or "spp." because you're pretty much saying "Any species within a genus that begins with E"What's cryptic about it...sp. stands for species. Done. That's not so hard to remember is it?
