apparently the only way to tell the difference between Virginia and Carolina spring beauty is by the leaves. Virginia is very long and narrow - almost grass-like, while Carolina is more oval. Here are some sources

I did come across a source that said the little nibbet on the stem of Virginia will be fleshy, while on caroliniana it will be papery... but I seem to have lost that source.

There is also apparently a whole blog devoted to Claytonia - here is a helpful entry on distinguishing Miner's Lettuce from Claytonia Rubra. This also may be a source to reach out to for questions - they seem to encourage it.

Finally found eFloras entry - apparently they put the family as portulaca.

Claytonia in Arkansas
There's a neat species endemic to Arkansas that is relatively new (identified in 2013). Seems like most of the documentation of C. caroliniana is actually a misidentification of C. arkansana, a cliff-dwelling species of Claytonia.
Pretty amazing - apparently it has the ability to seek out dark crevices with its fruiting stalks, to redeposit seeds back into the cliff face.

Here is the technical report describing the species and documenting the confusion with C. caroliniana

Here is another general ID page for C. virginica from Arkansas. It briefly describes the differences at the bottom. I like the thorough description of virginica's growth habits, though.
