Perhaps Abelmoschus manihot called "pele" in Hawaii and "bele" in Fiji. Picture of leaves here: http://www.huffingtonpost.com/rob-kay/hawaii-eating-on-the-wild-side_b_4405431.html FataMorgana

It could be Sedum tetractinum 'Coral Reef'; but it is quite etiolated. Any succulent will do best in good light, most like quite a few hours of direct sunshine. If my plant, I would cut off all long stems, pull off few lowest leaves; let it callus for few hrs-a day; and finally pot into better mix (can't tell for sure what yours is like, but looks dense. Mixing in lots of sifted perlite - like 50% of total volume - would help). Existing plant needs more light and will continue growing leggy unless you change that. Best if grown outdoors...depending where you are located, it may be hardy...slowly acclimatize to better light, otherwise it will burn.

I was thinking that probably some greedy poor natives are digging up those beautiful plants and selling them on ebay. Just like the same kind of people that are collecting every last native ginseng plant in the south over here. Just like feathers in British hats nearly wiped out the most gorgeous birds in the world. It's such a shame that so many blind people have no reverence for nature at all. I'm sure Sudan would agree with me. He was the last living African male Northern White Rhino in the world. And he died in May. All attempts to bring back the species have failed. They are probably gone forever. While rich Chinese gloat to their friends about their rare horn potion that they use for an erection. ( myth) They will reap what they sow.https://youtu.be/ALPwujKU4bs

I did go out and try to crush some leaves and see if there was a little garlic smell, but no. And some of the stems have a slight red coloring. I am going to have to try digging some out to see what it is....thanks for extra photos Rouge. I'm not sure which one it looks more like.
