I don't get into it that much. Just not my jam.When I got my first Beallara I researched just enough to be dangerous and took the first couple of bits as gospel.
Travaldo's blog site: Beallara orchid also called as Aliceara, the nothogenus for intergeneric hybrids between the orchid genera Brassia, Cochlioda, Miltonia and Odontoglossum. To achieve this cross breeders usually cross Miltassia (Miltonia x Brassia) with Odontodia (Odontoglossum x Cochlioda).
AOS: Beallara (bee-ul-AH-rah) A former hybrid genus derived from Brassia, Cochlioda, Miltonia and Odontoglossum, it was created in 1970 and named after Beall's Nursery. With the reorganization of the Onciidinae, this hybrid genus now becomes Aliceara.
I think Beallara, now Aliceara, are synonymous. And I don't have the patience to keep up with all the naming, renaming those silly taxonomists run around doing. It messes up my labels and spreadsheet. I have little patience for it.
