Hello, I´m a new in this forum and I have a cuestion. I think this plant does not belong to Selenicereus testudo. Someone could tell me what is the origin of this beautiful plant and if you have photos of the open flower.
Thanks in advance.

Chuck.

Hello, Chuck. I just replied to the dmail that you sent me. I had this plant for several years. It started out as a small plant (see picture below). I believe it was labeled "rat's tail" or something like that. Eventually, it grew quite large and sent up three-side thorny stalks in addition to the many four-sided ones. I did miss the opening of this flower, but this was the picture of the flower bud. This plant was covered in painful spines so I did not take it with me when I moved.

I too am interested in protecting the identification of all plants in general. I think I verified it's identity before I posted it. I'll see if I can find a link to another site which has a similar plant to my former plant.

Well, I can't verify that this flower is actually on the selenicereus testudo plant, and I have since moved. I had some hylocereus in the same area so maybe it was a hylocereus flower, and I put the wrong name to it. Dave's administration can delete this picture and this thread if they wish. The other pictures of mine of Selenicereus testudo are the correct identification.

Thanks for your answer Clare. I think too that the plant is an Hylocereus sp., but it´s very interesting for the red scales of the flower bud.
I guess the plant comes from Mexico or Central America. I know some species of southeastern Mexico, but I had never seen a Hylocereus flower´s with red scales. I suppose also the open flowers must be white or yellow. It's a shame that you miss the opening of this flower.
