G'day guys...

Here's a plant I got some time ago from Collector's Corner. It seems to be relatively slow growing, and is maybe five inches tall.



Any ideas?

Isn't that what they use to call Opuntia tuna (or something along those lines)?

Yeah I certainly considered that... I must admit I'm not too flash when it comes to IDing this sort of plant. The opuntiads seem to have the most confused nomenclature of any cacti; I've seen so many different groupings - Opuntia, Cylindropuntia, Micropuntia, Puna, Tephrocactus, Mauhuenopsis, Pterocactus, Consolea, Corynopuntia... study

I thought I'd give IDing it a go neverthess... this is a plant that I've seen for sale reasonably often - including at weekend markets - so I'm tipping someone knows what the bloody thing is! Laughing

TasV, I don't think this is Opuntia tuna... I thought that was a larger species, more conventionally prickly pear-like in habit?

Also seen references to O. rufida f. dwarf

Well I reckon that photo is very interesting... my references give a totally different picture for O. tuna - however I reckon there's definitely something here. O. rufida... isn't that the "cow blinder", a big nasty plant with massive glochids?

This looks like it too but I've never heard it called this: http://www.thesucculentgarden.com.au/opunt.html but by the look of this it might be a legitimate name: http://www.google.com.au/images?hl=en&lr=&q=Opuntia%20microdasys%20var.%20rufida&um=1&ie=UTF-8&source=og&sa=N&tab=wi

So it's a mini-me rufida then... at least we're got something to go on now.

These miniature, clumping species are definitely a favourite of mine.

I hope you've got microdasys then... common but just so beautiful.
