I'm always a little confused when trying to know exactly what each different anubias is in terms of scientific classification. I know that coffeefolia, nana, petite, and broad leaf are all part of the Anubias barteri complex, and that there are a few others that I believe also fall under this species, such as micro (and I'm assuming snow white and variegated and stardust as well).
I'm just wondering what variations belong to this species and are not a different species from barteri.
"coffeefolia" is not a valid, published species. It is, according to Kasselmann, a growth form (natural?) of A. barteri var barteri. Most all of those cultivars you mention are derived from A. barteri. See: http://www.theplantlist.org/tpl/search?q=anubias
Definitely. We need to stop using trade names and use only genus, species and if no species, then a region name...not junk like "butterfly" or really outdated names like ammania bonsai and ludwigia peruensis. It really grinds my gears.
Generally speaking, if a species name isn't given like congensis or hastifolia, it's a barteri cultivar.
Wait, I thought Ammania sp. Bonsai WAS the proper name for that plant (I've seen it called Rotala Indica 'True' which makes less sense to me tbh). What is that plant supposed to be called then?
And yah, I feel with anubias though, you can find things online claiming congensis to be Anubias congensis, as if its a different species. Doesn't help either that some barteri cultivations look like different species of anubias that are legitimately different species.
