I have yet to flower Hoya yuennanensis, but it differs from Hoya lyi in habitat and flower characteristics. H. yuennanensis is a rampant climber that is found in exposed locations where as Hoya lyi is found in the deep shade. Hoya lyi has a different shaped corona that is broadened and flatter with smaller pollen masses then those found on Hoya yuennanensis.
