Sorry for the delayed response! I think I expected to get an email notification about replies and so I forgot to log back in and actually check.
The full checklist was published online in September 2022, you can view it all for free at
https://tradescantia.uk/checkl.... There is a page for every single cultivar name I've found in use (about 460!). Each entry explains whether it's a unique name for a real cultivar, or a synonym/trade name that refers to another plant. And for each unique cultivar (about 260) there is information about its origins, description, and photos wherever possible.

Are you able to explain if these are actual cultivars, or just the common names being confused as cultivar names?
Purple Heart (Tradescantia pallida 'Purpurea')
They are a cultivar, but they're the *same* cultivar! The correct name is T. pallida 'Purpurea', but it's sold with various other trade names including purple heart, purple queen, purple passion, and others. Here's the cultivar checklist page:
https://tradescantia.uk/cultiv....
And how one identifies this cultivar, what is the distinguishing feature?:
Tradescantia pallida 'Kartuz Giant'
Unfortunately the picture on that page is wrong - it shows the more common 'Purpurea' cultivar from above. The distinguishing feature of true 'Kartuz Giant' is that it has extremely wide leaves - almost as wide as they are long, to the point that they become pleated where they meet the stem. Here's the checklist page which has some photos:

Is this just T. pallida species in lower light?:
Tradescantia pallida 'Blue Sue'
No, this is another cultivar too. Its appearance does change in different light levels (like pretty much all tradescantias), but in ideal conditions it is dusty blue with just a hint of purple - much paler than 'Purpurea'. Both 'Blue Sue' and 'Purpurea' originated as wild collections of the species, but they have their own unique distinguishable traits so they are different cultivars.

Is this a Callisia?:
Not a Callisia, another distinct cultivar of T. pallida. In this case the most unique feature is that its flowers are pure white, rather than pink like most others of the species. More photos on the checklist page again:

Hope that all helps!

I'm pretty sure I have one single donate link in the footer of the website, so that may be why you think I'm writing it after every article? 😅 Being ICRA is an official position, managed by the International Society for Horticultural Science (here's their page about ICRAs:
https://www.ishs.org/nomenclat...). But it's not a *paid* position, so I sell plants and accept donations to help fund my work and research.
