Not sure what this is...

....it has a cacti kind of look, rather large and the flowers come up on a long stem, like a candalarbra.  It was starting to get dark with a little rain when I finallly got around to take a photo for my Blip.....stood at the front door and zoomed in on this flower. 
I had oldTimer here for much of the afternoon, she was wanting to order a canvas and needed some help to get it sorted, their website seemed rather complicated.  Anyhoo, job done, fingers crossed it will be OK.
