THANK YOU, antisepp, you never fail.
I have not been able to thank you before. Regards

It will be difficult because they are still very small
1 looks like Rebutia.
2 and 3 look like Echinopsis
GRACIAS

¿1 REBUTIA?
¿2 ECHINOCACTUS?
3 NO IDEA, WITH THOSE THORNS SO WHITE

las espinas rojas son pintadas

pue si ANTISEPP,PARECE QUE SON ESOS
MUCHAS GRACIAS

la 1 me parece Echinopsis ferox, PERO NO ESTOY MUY CONVENCIDO
La 2 parece Rebutia,no lo se
la 2 parece Turbinicarpus,quizas pseudomacrochele, pero tambien podria ser un hibrido,no se.
gracias

It looks a lot like Echinopsis cardenasiana, ancient Lobivia, I don't know...
perhaps also Acanthoplegma, Colorubra or Maximiliana... but I am not an eminence

I'll look quietly in my books, maybe it's M. karwinskiana or as Tom says
http://www.llifle.com/Encyclopedia/CACT ... nejapensis
although I see the very long spines.
Well, we'll see when he grows up.
Anyway thank you very much

2 looks like Mammillaria
EL 1 reminds me of Parodia leninghausii cv. longispina.but it doesn't fit me because it doesn't have hooked spines like mine
look at the longispina and compare https://cactosbonitos.wordpress.com/200 ... ongispina/

COMPRESSA.GRACIAS

at first I thought it was pseudocrucigera, but the spination is different
what will it be?

the thorns as black as his are not observed

mira a ver Stenocactus Skrynkelkaktus crispatus

I have put s.angelis because it seemed more like me. In any case, in other forums they dismiss them as haageana, I don't know what they are based on, maybe because they don't have so many basal shoots. On what basis do you consider it Haagean and not other species such as http://www.llifle.com/Encyc...

it is the same in different states.
I have doubts between Mammillaria haageana ssp. san-angelensis or Mammillaria albilanata ssp. Oaxacan
OR None of the above.
THANK YOU
