I bought a cutting of this hoya from Ted Green in 2006. It flowers early and the campanualte flowers spread a nice scent of citrus in the evenings. Overall it looks like Hoya wallichii, but is smaller in all measures. It can be tricky to grow supported on a trellis as it does not twine and the stem breaks easily when trying to bend them. As this hoya has thin leaves I do not let it dry completely between waterings.

It was published by Blume as Cystidianthus laurifolius. In 1913 Engler moved the plants in the Cystidianthus genus to the Hoya

genus (Botanisch Jahrbücher für Systematik, Pflanzenengeschichte und Pflanzengeographie 50, p. 127) and then refered to a publication made by Schlechter stating that this plant shall be namned Hoya cystiantha. The problem is that Schlechter never made that publication and therefore that name is not valid. The common rule says that when a plant is moved from one genus to another it shall keep its species name, but in this case it is not possible as another plant already had been published as Hoya laurifolia. So until anyone makes a proper publication of this species it will remain in "naming limbo". Some claim that this is Hoya campanulata.
