Flowering cactus

There is a minuture cactus in a pot in the garden and two days ago when I went out it had this huge flower on it. I thought that when I got home from work I would take some photographs of it, then changed my mind and decided to do it immediately.
Just as well because by the time I got home, the flower had died. I did not know that some of them only last for a day.

The plant itself is only about 2 inches in height and the flower must have been 7 or 8 inches. I was happy you have got some pictures of its beauty.
