Any idea what plant it could be? My first guess was Selenicereus sp. found in north-east, Mexico (close to Santiago, Nuevo Leon). Grows like a creeping vine, up a tree trunk and then dangles down, aerial roots are abundant, fruit seems to be green in color (haven’t seen one turn a different color yet), weak and slightly flexible thorns that do not dislodge from the plant easily, pentagonical stem. If identifying the actual species is possible I’d appreciate that.
