Nomenclatural notes
Note: Docidium crenulatum Ralfs (1848: 219), the earliest supposed, post-starting point date, basionym is a nomen nudum; and in any case Ralfs says 'Professor Bailey informs me that this plant is identical with Docidium nodulosum' and it cannot thus serve a basionym on two counts. The binomial should thus be ascribed solely to Rabenhorst. - (26 Feb 2010) - M.D. Guiry
