thanks for all the responses, unfortunately when reducing the image to post i didn't save the original so i cant repost.
Welcome flegmatik, it's hard to tell 'cos so many Ephedra sp look so similar and also the pics are not the best (size-wise) but I think the middle 1 may be E viridis...
The brown 1 looks a little bit like Casuarina sp...
germinator, viridis was my guess also, as for the one on the left it had dried out completely before the pic was taken (stuck in my scanner and scanned actually) which is why the colour is so different to the others, but I think you may be right in that it isnt ephedra as it didnt break apart at the joints like the ephedra I have played around with do.
the one on the right hand side is fragilis (as far as the person who owns the plant told me anyway) and the pic shows two different cuts off the same plant. the middle one is growing next to a railway station somewhere in vic, so anyone that catches trains in vic keep your eyes peeled lol.
the friend with the fragilis said when he has been cleaning up his garden he has sometimes pulled out stray bits with roots on it and if it wont kill his plant (which is the last thing i want to be responsible for) hes happy to give me a decent cutting (still cutting if its got roots?) but before he does that i thought i would check if i could get a plant going with this method, i am aware that you cant grow it from cuttings as such but is it different if you have a decent amount of root attached? like i said last thing i want to do is make him kill his pride and joy.. especially if its a pointless excercise from the start..
thanks again for the replies, and if anyone has experience with the cutting thing would appreciate the feedback
