I have this thorny, leafy plant which I do not know what it is. I am not sure if it is a palm or cactus. Once I was in a bookstore and saw the plant in a book but did not write the name down. The book I saw had the plant over 10 feet high. Any help would be appreciated. Sorry for the small picture but that is all I have right now. If I have time I will try to take better pictures and up load. Thanks Don
