This is kind of a big mess. Our Lampranthus and Oscularia entries are all mixed up, listing accepted names as synonyms and vice-versa. I'll fix those as soon as I get back from an appointment. In the meantime, I hope Tarev can weigh in and tell us how the plant was identified as two different plants.
I'm also having trouble finding the posts numbered 365406 and 356704. Can you tell me the name or number of the thread instead?
