Excellent!
Glad the article helped.

Tunilla chilensis?

Here's what i have as E. taltalensis 'violaciflora'
Blooming about 2 weeks ago, although i find it can bloom sporadicaly almost any time of year.

I guess i'll accept the blame
Another possibility is Cyl. thurberi which grows in Sonora.

I'd be hard pressed to tell these apart!
Have a look here:

Right, Cyl. californica is bigger all around, stems, buds, flowers. The flowers are more of a bright lemon color.

The full view pic does reveal some questionability from the plants i've seen in Arizona, but they are variable. And all i have is my phone screen, so i might be missing something.

I think its Cyl. arbuscula.

These don't branch until several feet tall and they branch from the top or close to it. Branches at the base suggest damage as a young plant or right from the get go.

Is it unusual? Yes. But still makes for a nice plant!

Mammillaria deherdtiana?

I've collected about 75 packets of seed from our plants and got another 30+ from a friend. My 'busy' is about to tripple!
It's been so warm here lately i'm almost tempted to clear out the last sowing batch to make even more room. I might be going mad
