Great shots. The plants are damp but I'm guessing they haven't had a lot of rain yet this year?

Great pics, Vladimir! And what lovely red spines! I'd be interested to know if they grow this strongly coloured in the UK.. anybody have one?

I wonder why they are red? Surely they don't need to tell the herbivores, "Don't eat me, I'm red and dangerous!"

Julie, spines are wet - that is why. I have posted some closeups of that spicies before - thay are dirty-gray-brown, not so colorful when dry.
Growing spines that large in UK - that would be a challange

Iann - it was September, the first may be rain that season. I was camping when it started - a lot of hissing sounds emerging from the soil (not sure soil is apliccable word?) and very dense smells of wet plants and rocks - like usual grass smell when it rains after drought, but multiplied by x100

Sounds like a beautiful camping experience, Vladimir. My camping has been confined to music and hippy festivals so far, which requires different survival skills, and... er... have different scents!

I'd like to go somewhere really wild (as in remote!) but I think I'd be terrified not to be surrounded by other tents.

Is there something in the soil there, which is needed for large spines? I always thought they were sort of plant keratin equivalent, but do they contain minerals such as calcium from alkaline soil?

Julie, it is hard to be along when you camo within 5 miles of a large city like Vegas :))

Speaking of spines.. Why you think calcium matters? Spines are not bones and plants are not animals :) Spines are made of wood - sort of, which is chemically almost sugar - carbo-hydrates..

There are svevral enviromental factors that add to growing large spines. These are:
- plants must be healthy and well, and well-fed :))
- A lot of sun helps, but not to much - plants must be healthy, remember;
- Large day-night temperature range seems to help, not sure about all plants - again may be it is just that healthy thing. There is some link between CAM efficiency and low night temperaures.
- it is known that spines grouth is stimulated by local concentranion of gibberelines in areole, not sure how use that knowledge for artifitial stimulation

Aaah I see. I wondered what they are made of!

Still a beautiful campsite... and less neighbours than here... I can't say where in the pic our camp was, as I lost my sense of direction. I think it might be off the left hand side. We were by an empty field, anyhow... being among the last to arrive.

Can someone please explain what CAM is? It has been mentioned twice recently and I think I have kind of heard of it but I can't think what it is
