Nomenclatural notes
There is some uncertainty as to the nature of the specific epithet. According to Cassell's Latin Dictionary "morum" is a neuter noun, meaning a mulberry or blackberry fruit, whilst "morus", a feminine noun, is a blackberry tree. The adjective "morus, mora, morum" means silly or foolish. Accordingly, it seems clear that O.F. Müller found this mulberry- or, more likely, blackberry-like "Volvox" and called it Volvox morum using "morum" as a noun in apposition [otherwise he would have used morus if it were an adjective as Volvox is masculine], but Bory, when he transferred the entity to Pandorina, erroneously altered this to Pandorina mora, and the epithet should therefore be corrected to Pandorina morum. O.F.Müller would not be likely to name his "Volvox" after a tree (and would have used "morus"), and certainly would not have used the adjectival "morus" thinking his lovely microscopic "animal" was silly or foolish. - (31 Mar 2011) - M.D. Guiry
