At the site of E. chihuahuensis subsp. chihuahuensis, I found a plant that someone had dug up. The photo shows a root tuber. I haven't actually read anywhere
that henricksonii makes such huge tubers. Does anyone have any additional information?

There's no close relation with which this taxon can be compared with its tuberous root, slender, columnar stems ..."

At the same time, I am attaching a photo of the plant E. chihuahuensis subsp. chihuahuensis with roots from my collection.

Hello,
henricksonii has massive tuberous roots, this is evident even in culture (even more so in nature). Chihuahuensis too, but I would say a bit smaller. With it, we can talk about swollen roots, with henricksonii it is really a tuber.

Hello,
the attached photo confirms Jarda's conclusions. A pot with a diameter of 10 cm was not enough for the roots of this plant.
