Taxonomic Merge 66696 (Δημιουργήθηκε στις 24-12-2019)

Agave americana 'Marginata', Agave americana 'Picta' and many other plants created by humans are not real botanical varieties.

Both are just variegated cultivars of Agave americana without any taxonomic value.

There are hundreds of cultivars of Agave and tens of thousands of other plants, but iNaturalist is mainly about observing wildlife.

Some human made hybrid complexes have been described as species, for example Viola wittrockiana, Tulipa gesneriana, Chrysanthemum morifolium or Dahlia pinnata.
These names can be used for a wide range of cultivars but not all.

There is no such thing for Agave. Most Agave cultivars are either hybrids, selections or mutations that have been found.

Some cultivars like 'Marginata' can be identified to species level, this makes no sense for many other cultivars. I would recommend to ID these plants only to genus level.

Some examples:

While I tend to agree and don't really mind, I'm curious- are there any real drawbacks to having varieties in iNat? I mean, more information is always good, isn't it? in terms of public engagement, being able to identify something to a more specific level would increase engagement. In terms of research and biogeographical data, there is, without a doubt, gene flow (and often direct escapes/naturalization) between cultivated and wild populations. As such, having data about where different cultivars were at different times could be very valuable in the future. In terms of the platform, it seems like being able to label specific observations with more information would only help. After all, it makes it possible to do mass changes like taxon swaps and whatnot. If you merge all varieties into the species/genus level, you just lose data which would make it more difficult to separate potentially problematic observations. So... does including varieties create issues in the iNat platform or something?

As I said, i don't really care all that much, but it seems like there are more potential benefits to having the ability to label varieties than there are drawbacks.

The problem is that cultivars are often called varieties. Varieties are not the same as cultivars!

Agave americana 'Marginata' and Agave americana 'Picta' are only two from tens of thousands of human made cultivars. If we start adding cultivars as separate entries to iNaturalist we will end up with thousands of names for garden plants, potatoes and so on, but the main reason for iNaturalist are observations of wildlife!

Of course it is absolutely ok to add observations of cultivars (if you mark them as cultivated or if they have escaped into the wild), but we should have a scientific approach and identify to the real taxonomic rank.

If you know a certain cultivar name, if a plant is in reality a hybrid etc., you can also write it in a small text in your ID.
