Discussion | Subspecies 4 (3 in the flora). Honckenya peploides is polymorphic. A number of species and infraspecific taxa have been described from various parts of its geographical range. Recently, four subspecies of H. peploides have been recognized (A. Kurtto 2001b; V. V. Petrovsky 1971, 2000), as here; subsp. peploides occurs along European coasts. Honckenya is subdioecious (Petrovsky 1971, 2000; T. Tsukui and T. Sugawara 1992), and is pollinated largely by small bees, hover-flies, flies, and ants (Tsukui and Sugawara). The report of Honckenya (as Ammodenia) in Chile is an error based on G. Macloskie (1903–1914, vol. 1) (C. Marticorena, pers. comm.).
