Hoya pubicorolla ssp. anthracina is well-known in the past years as Hoya pubicalyx 'Black Dragon'. The latter is just a coined 'variety' in commerce to describe its blackish color. The collector is from here in the country, but sold his collection first as export to the western countries but not locally. In effect, the foreign collectors already have it growing beautifully and all of us here in the country are in awe where we can get it. I was just lucky to have connection with some people and was able to get a plant from the collector. Later, when my plant flowered i was so surprised as it is not as black as the photos circling in the net.
I just learned lately that there are two forms of this as collected here. One was real black and the second is the more maroon one just like mine, as presented in the photos below. A friend from Europe offered to give me a cutting of the black form, know someone who might come here for the holidays. I hope there will be a person to bring that from Europe to Manila. I am almost close to praying!
The newer name, Hoya pubicorolla ssp. anthracina, is given by RD Kloppenburg, a former collector who gave names to most of the Philippine hoyas. He was also responsible for the controversial names of many species, as he sometimes give a new name to already identified ones. Lack of knowledge on the characteristics of hoyas to change forms, colors, and leaves shapes through time and growing conditions predisposed the Philippine hoyas to have chaotic names, others actually said "naming of Philippine hoyas is a mess". Nobody seems to be entering the mess to correct it.

Sometimes the form is like above, but sometimes it is like below. They seem to be different, but they are in the same plant. That is true with the corolla, but the corona of above and below are the same.
I love its characteristics of producing continuous umbels for many months. They seem to be always there every month, however there are not as many umbels in one plant as compared to Hoya carnosa.
Above is the typical plant, shiny green leaves without very prominent venations. The internodes are a bit longer than the other Hoya pubicalyx, but the shape and size of the umbels are just like it. Leaves vary in sizes too, there are leaves which are sometimes longer than the average, as you will see in the above photo. There also a few umbels at the back.
One of my pot has stems that climbed the lanzones tree. I was not able to see that until i saw an umbel of open flowers as above. I did not remove it anymore, let it climb some more, and this umbel has been flowering for maybe already 6 times. A previous flowering was included in the Hoya Telegrafen, a publication of Sweden, as the editor requested my photo.
