Oscularia vredenburgensis is an accepted species name, according to the Catalogue of Life. You're misspelling the name as "vredenbugensis," Leslie.

You probably didn't "goof on the synonym." I've already corrected some of these entries. Oscularia caulescens and Oscularia deltoides are separate and distinct species, so they never should have been combined as synonyms of Lampranthus deltoides, which is itself a synonym of Oscularia deltoides. Some fun, eh?
All of the photos ended up on the Oscularia caulescens page, but
@Calif_Sue and
@jojoe should check their photos to make sure they aren't supposed to be in the new entry for Oscularia deltoides (previously listed as a synonym, along with Lampranthus deltoides, in the O. caulescens entry). Also,
@Valleylynn also says she owns this plant, so she should check to make sure she has O. caulescens rather than O. deltoides.
