Anyone know these plants? The first must be a Parodia, but the species? And is the second also a Parodia? Or a Gymnocalycium?

#2 could be Parodia ottonis.

[sabotenmen]

Thank you, Greenknight. It would be nice if it's an ottonis. It's easy to make new plants with the offsets of ottonis ,that often already have some roots on them. This appeals to me.

#1 Could be Parodia scopa or Parodia eurubescens

[Shmuel]

#1 looks like a Mammillaria from the apex, but I can't tell if it has ribs or tuberculate spirals.

#2 looks more like a Melocactus or Echinopsis to me. The stout spines and distinct ribs whisper "not a Parodia" to me.

I think you are right about the plant being an erubescens Salazar. Close relative of the scopa. Thanks a lot.

Thanks for helping me with number two, Shmuel.

I agree with Spence, number 2 is one of the Parodia(Notocactus) ottonis group, probably ottonis. There are quite a few names in the group, particularly at variety level, but most look similar, ottonis, oxycostatus, linkii etc.

I've been fooled by their resemblance to Melocactus before, my first reaction to this one was "it's a Melo" - but those spines don't fit any Melocactus. When I looked closely at those, the light dawned - those are the spines of P. ottonis. Some have denser spines than this, some even have less, but their form is consistent. I can certainly understand the confusion, though.

[Shmuel]

Well, the pseudo- Melo spines sure gor me. Of course the old "wait till it flowers" is always the bottom line.
Thanks greenknight.

A sense of scale in photographs is often the problem Shmuel, since I once read where a lady identified her Rebutia as Echinocactus grusonii from a small picture in a book. Obviously if she had been able to compare sizes the mistake would not have happened.
