I have about 100 seedlings up from sowings of Pterocactus seeds from bought from Elisabeth and Norbert Sarnes (thank you) at the TSG meeting a couple of weeks ago. Of all of those, two of the three of P skottsbergii SAR 2971 which have germinated have three cotyledons (the 'fourth' is actually the stem at an oblique angle). I'll obviously keep an eye on them; there's presumably a bit of genetic mutation going on, so it will be interesting to see how they develop. Or will it? Anyone else has this from these seeds?

Most of mine have three cotyledons must be a trait of the species.
I was quiet surprised by the quick germination for these and the Tephrocactus I bought at TSG.

Thee is an article in the latest (Summer 2023) CSSA Journal about Pterocacti doing this, by Root Groelick.

Thanks for that Ralph.
