Unknown plant found in Malaysia

This post is especially for the very special flowering plant i found in Malaysia. I specifically post it here so AutumnBelle or Jacq might be able to identify it. They are plant hobbyists from that country and if i am lucky enough, they might also have some friends who might help us identify it. According to my friend and generous host, Aminah, it is called 7 needles (Pereskia corrugata/bleo). It is obvious because of the 7 thick thorns arising from the same spot. She said it is a known medicinal plant there.

I've known Aminah since our CSIRO days in North Ryde, NSW, Australia. We stayed also in one flat during our last month in Chatswood.

We have lost touch for a while but after thorough internet search i was able to contact her. She gladly invited me and my travel buddy to stay in their big house for the whole duration of our KL vacation. They were so very busy in their academic works, but also very generous and accomodating that we were advised to feel at home, and we just cook and eat whenever we are left in the house. Their only daughter drove us around KL, Putrajaya and Genting Highlands. I was also asked to give a seminar on Intellectual Property Management at the University Kebangsaan Malaysia. It was attended by the university faculty, staff and graduate students.
