It is hard for an old timer like me to adjust to all of these changes, but I just heard that Hoya pubicalyx has now been renamed Hoya pubicorolla.  So I guess I will have to roll with it.  Here is a photo taken this morning of the former Hoya pubicalyx Royal Hawaian Purple.  The colors on these can range from almost black to washed out red depending upon the conditions under which it is grown.  The top photo is of a pencil sketch feature done in photo processing software, which I think makes a nice effect.
