The first Hoya I have is given by my Hoya scientist-friend, who crossed the spirit world last December, after a long battle with the big C. Being the new authority on Hoya in the country, she found a nameless species in our Hoya-rich plant kingdom, and authorities in Hoya-world honored the species with her name, Hoya siariae Kloppenburg. Unfortunately, I still do not have her namesake in my Hoya kingdom. But it is already in my wish list.

Another hoya which I acquired long ago was nameless. I just put it in a driftwood near our house together with another self supporting orchid. Last year's severe dry season almost killed it, but produced stems again coming rainy season. Since it was exposed to full sun, i got a cutting from the mother plant last Feb and put it in partially shaded area to root, with coconut husks to maintain moisture. Maybe it wants to teach me a strong lesson! There was no apparent roots yet being less than two months from cutting, but it produced the peduncle where flowers arise.

Now i think i am hooked. When the flowers opened, the scent is citrusy sweet that is really lovely, not loud but just soft which you will smell repeatedly. This is the start of my quest for identifying it. I shortlisted all the names nearest in morphology to mine, including the leaves and other plant parts. My friend who got Siar's book also emailed me a shortlist and some descriptions. I got nine shortlisted names. Even with a stronger background on plants, i still found it very difficult. I realized Hoyas have different flower forms even within a single name. I eventually reached just 2, but the leaf shapes did not fit mine, so i change one to another, which turned out to have short internodes, opposite of mine. GRRR, i am almost at my limit!
After settling on the 2 shortlist among the shortlists, I still don't know its name, I am still lost and not convinced. I am so disappointed to be going home with something hanging in my mind! So the last resort is to search for the next hoya authority name whom I personally know and ask! After a long night of waiting, his reply is already in my inbox this morning. EUREKA! My now very very expensive plant, because of the difficulties it has given me, is now baptized Hoya crassicaulis. WHEW!
My gratitude to Mr Fernando Aurigue for ending my search.
