New cactus

I rescued a little cactus from being neglected in a local shop. It was labelled 'Echinopsis' but doesn't look like one to me.
I discovered it is actually Mammillaria oruga



Lots more flowers are opening on my red Epiphyllum (but it's a bit shapeless) ...

 

Unusual mamillaria there Michael, good find.

 

Ive not seen this one either but its intresting , Is the white parts the flowers ?

 

The white bits are tufty hairs, it's where the spines would be if it had them. The flowers would be in between the tubercles but it has not flowered yet.

 

Will be interesting to see when flowering.

 

When it flowers I will post a photo .

 

Thanks

Will look forward to seeing this in flower.

 

The white bits reminded me of little rosebuds
