ric rac or fishbone cactus
 

this is an epiphyllum of some sort known as the fishbone or ric rac cactus,...a friend gave me a cutting and i have propagated it....it looks neat kept at low light but it wont bloom....in order to get it to bloom you have to give it very hi light to the point of burning the plant....but i did get a bloom....unfortunately, i didnt get the photo till it was fading....duh....but here is what it looked like for those who are curious....nice red...with white center....
