September 2015, 'Perfect spines and spikes'

[Liz M]

So, here is September's title. I look forward to some picturesque sharp and spiky plants.

[John Dos]

Sharp and spiky if you are very little ...

[Tony R]

If it is spines, then it has to be 'small Opuntias'

Tephrocactus aoracanthus

Maihueniopsis hickenii P102

Maihueniopsis glomerata

[Jim_Mercer]

Not sure about "perfect" but there are plenty of spines on this mammillaria (for flowers see May's thread)

Mammillaria pseudoperbella

Also not sure if the pointed bits on this delosperma count as spines but perhaps they are spikes

Delosperma echinatum

If it is spines, then it has to be 'small Opuntias'

Not at all.

I think this is a Weingartia. NOT my plant I hasten to add. Always catches the eye at our branch show.

I like G. spegazzinii too. This is var punillense.

And spiny urchins

And Echinocactus polycephalus

[Ivan]

I too like Gymno. spegazzinii
From Dan and yours just adds to it. Like a little thorn shower. Thanks
It's time to put some serious effort and get some seeds growing.

Perfect spines? I would say "yes".
So - I will show you my favorit Echinocactus horizonthalonius from Generel Cepeda, Mexico:
