Alocasia ID's needed, please

I have little experience with alocasias as they are generally less hardy here, but I have quite a few with somewhat ambiguous ID's and I can't tell them apart...I'll post individual pics of each

Clockwise from top left:
1-Labeled 'Cal'--from a friend--we couldn't figure out if it was 'Calidora' or 'California' (gageana)at the time
2-UnID alocasia from trade
3-Brian IDed this one as gageana last year, was a gift from a nursery owner in western NC that didn't know the name. It has pupped like crazy
3-a pup from the above plant, it just had the largest leaf I could find on these
4-new plant from trade labeled 'Odora'

I know that they are all smaller so that may make it hard

#1--the leaf--sorry about that

#1 backside of leaf

#1--the base

#2--leaf--new picture software, sorry about the rotation

#2--from the top

#1 is definitely Alocasia gageana; #2 could be A. odora. Did you grow these from seeds, or from corms?

#2--backside of leaf

Also, #2 could be a small A. x calidora. Be sure to look back to my first post.

from corms--gosh, where can I get seeds! lol--These aren't looking great, it's hard to keep my little GH warm enough for them.

#2--the base

#3's--plants--the one in the larger pot looks skimpy because I pulled most of the pups

#3--leaves

#3s are a little too young to be sure, but my first guess is that the larger one is the same as #2, and the smaller ones are A. gageana. But when they get larger, I may change my mind!

I have seeds at various times in the year but they have to be planted very fresh. Right now I have two pods of Alocasia berries waiting for me to clean and soak for planting. They are from my Alocasa 'Big Mac', which I think is a seedling selection of Borneo Giant.

#3--the base--this one tuber produced over a dozen pups since last summer

OK, the quantity of pups argues in favor of A. gageana, as that plant is extremely prolific with corms and pups. A. odora is not nearly as prolific. The only other Alocasia I know of that is as prolific is the very common A. macrorrhizos, which I am fairly certain you do not have there.

so I might just have all gageana then?..lol..that's what I was afraid of

#4--leaf--it just got here, and looks well traveled :)

Now #4 looks a lot more like A. odora or A. x calidora.

that's the only pic I took of the new 'odora',

but I did get the backsides of #'s 1, 2, 3 because they looked so alike

we seem to be cross posting a lot, you may already answer this, but how can you tell a difference?

one thing I've noticed is that #1 seems brighter green to me?? but that might just be different medium or something

I go by the overall look of the leaves, based on years of experience with these plants. Leaf edges, number of lateral veins, overall leaf shape, the sinus at the base of the leaves are some of the characteristics I look at. Mostly, though, I end up with a "feel" for the plant and most of the time it works out right.

I really appreciate the help and I recall my friend that gave me #1 (definitely gageana) saying the leaves were more heart-shaped and veins a little closer together on either the Calidora or gageana (sorry, that's how I learned it andhave a hard time re-training..lol) but can't remember which.

Both #s 1 and 3 are pupping well, but #2 doesn't show any signs,---maybe I am hoping I don't have so much of the same plant :)

Oh I am jealous!!! ☻

What is the purple stuff in the first picture?

It is oxalis 'mijke', does well under taros and is hardy here. In a lot of places oxalis is considered invasive but I haven't had a problem out of any of mine

I have plenty if you'd like to try, I can send some when it gets a little warmer

yeah, I'd like that.
