The plant that I have which has been identified as Hoya apoda, from a consensus of internet Hoya experts, is different than the plant that I received as Hoya evelinae in only a couple of ways. The leaves of H. evelinae are about 1/3 larger than on H. apoda, and H. apoda never has more than one flower emerge at a time from a peduncle, whereas H. evelinae many times has 2 or more.
