Are they Notocactus ?

Notocactus ? or Parodia
or non of the above !

I think years ago we had flowering success with Notocactus and perhaps we should be looking to get some more.
So I did a trawl through my millions of digital photos
(! isnt it amazing how many pics you take with these new-fangled things compared to film !!)
and found these two candidates from 2008.

The yellow one looks possible, any guesses to ID ?
and whilst googling images found some that look like the red one, but maybe mistaken googles ?
Or perhaps both are Notocactus, what think ?

And then, wikipedia informs me that Notocactus are no more
and that they should all be Parodia, arghhh, a new genus to me but apparently been causing consternation since the '80s.

Notocactus submammulosus (Parodia submammulosa) and probably N. haselbergii (P. haselbergii)

[Phil_SK]

and probably N. haselbergii (P. haselbergii)

I think this one's P. penicillata.

Thank you.

The bottom one is definitely not Notocactus haselbergii, but is a Parodia (of the non-Notocactus kind).

[MalcolmP2]

Thanks y'alls

> "Parodia (of the non-Notocactus kind)"

Is there anywhere a dummies guide to the distinguishing of Notocactus kind from the not kind !?

https://en.wikipedia.org/wiki/Parodia#Species
I am slowly working my way through googling all those not in the Group notocactus, lots are yellow flowered but so far, in red, as well as P. penicillata :-
I have found P. nivosa which may be another possible ?

Interesting stuff.

You need Bradleya 2018 - a very comprehensive article on Parodia in the broad sense with photos of every species accepted by the authors. Interesting to read how threatened by agriculture some of them are.

Although we should all encourage everyone to support Bradleya it's also available as a download on the authors' website www.cactusinhabitat.org. A very interesting site if south american cacti are your thing.

Good find Nick, thank you.

There is also a new book by that well known author J Pilbeam entitled ‘ Parodia and Notocactus (the happy couple) ‘ giving his take on the two groups.
