Thanks for your help


Answer
Dear Maryann,

I think it may be Hylocereus minutiflorus. Please check out this website for more information. http://www.desert-tropicals.com/Plants/Cactaceae/Hylocereus_minutiflorus.html
Hopefully this is your plant, if not, I'm pretty sure it is a Hylocereus. Take care!

Sincerely,

Greg
