I goofed on the synonym..
Spent way to much time in the Plant List/Catalogue of life. What was wrong with the original tag? Oscularia caulescens. I know I purchase many plants that I later find were miss-labeled. Which is maddening because I then pass along the miss-information during public tours. Nothings perfect! Now I cross check with ATP and the multiple photos from various sources is really key. Thats how I stumbled upon this. Oscularia vredenbugensis is an unresolved name in the PL and nonexistent in C of L. Hope your able to untangle this.
