Notes.

Although authorship of Drymaria arenarioides is often given as “ Willd. ex Schult., ” the name and description occur in a single paragraph followed by “ Reliq. Willd. MS. ” This represents direct association of Willdenow with both the name and the description, and Willdenow should be cited as author (see Turland et al. (2018), art. 46.3 example 15). Because the holotype in B was destroyed (Duke 1961; Hiepko 1987), we here designate the P specimen as the lectotype.
