I am not having a go at you for wanting to know which plant you have but I go to peoples gardens where every one has a lable. On checking them half will be wrongly named. Cacti are the worst because there are many which look similar even though they not only different species but different genera or more than likely a hybrid. We do a count of major and minor sines, of ribs and check the shape of areoles . Check the size, petal count and size of flowers before giving a definate yes or no to its specific name. Some cacti are very easily identified but others are almost impopssible for the amateur.
I recently saw a cactus in this forum identified as Disocactus ,( Rat tail cactus Shown in photo .) when it was more than likely a member of a differnt Genus as seen in the next photograph.
