The flowers seem to resemble most Hoya macgillivrayii. There are 2 others that are somewhat similar, H. onychoides and H. megalaster. Although it is hard to tell without seeing the corona and no leaves.... I would still say H. macgillivrayii.

I'm new at this so forgive me if I'm way off. I found pictures at http://www.asiaticanursery.com/index.cfm/fuseaction/plants.viewCategory/catID/54/index.htm #1 could be H. incrassata 'Eclipse' #2 could be H. australis 'Variegata'

I had 2 obscura plants before. One is the typical smaller leaved one, and the other had large leaves (like the hoya above). I ended up trading the large-leaved version to make room for more hoyas (STUPID!!). Anyway, there could be another type of obscura. I recently saw that Rob's Violet Barn sells a hoya called "Hoya obscura v longipedunculata" (I guess the "v" stands for "var"). Maybe that is what you have? I really don't know...it could be the same as regular obscura though. Gabi

I have celata (aka White Dragon" it's a super crazy strong grower :D I'm just hoping it lives through Winter here. I couldn't really find much on what temps it likes? It's Autumn now (I'm in Aus) and it's getting down to around 10c overnight sometimes now so I brought it indoors. We can get to around -3,4 over Winter. It was only a baby plant 4 months ago!
