Abstract

The taxonomy of Polygonatum in Japan is revised. Nine species, four nothospecies, including P. ×desoulavyi (= P. desoulavyi var. yezoense = P. miserum), P. ×domonense and P. ×azegamii (= P. desoulavyi var. azegamii), and six varieties are recognized. Desoulavy 142 is superseded by Desoulavy 143 (both in LE) as a lectotype of P. ×desoulavyi. It is presumed that P. ×desoulavyi, P. ×domonense and P. ×azegamii are hybrid derivatives between P. humile and P. involucratum, between P. involucratum and P. lasianthum, and between P. falcatum and P. involucratum, respectively. Polygonatum amabile is considered to be a species distinct from P. lasianthum, as in Yatabe's original species concept. Polygonatum trichosanthum is reduced to var. trichosanthum under P. falcatum. A key to the species, nothospecies and varieties is provided.
