Ha, dont blame me for collecting wild hoyas, just very interested in this epiphytic and there are not too much choice I can buy from chinese flower market.
I live in YunNan province of china, know as the most South West province of China and border with Vietnam, Myanmar , Lao and very close to Nepal, Thailand, so no strange there's aslo many curious hoya species.

Lets come with these 4 speices the first time(I sure will need help in the future, since i've told these are very common hoyas by local people live in the mountain, and i presume there will be also some not so common :)

This is the first one, leaves about 10cm long and 5cm broad,with very nice and abvious lines, so i think it would be the most easy to recognize by you :)
