Allium senescens L., Sp. Pl. 1: 299 (1753) Fig. 1U-Y

Allium pseudosenescens H.J.Choi & B.U.Oh, Brittonia 62(3): 200 (2010). Type: China. Heilongjiang, Tahe, Talin Linchang, H.J.Choi 080119 (Holotype: KH!; Isotypes: KH!).

Type.

Russia. From Siberia (forebaical region), LINN 419.25 (Lectotype: LINN photo!).

Notes.

Allium senescens , originally described from the Baikal area of Russia, is certainly one of the most popular ornamental Allium species of the world, and is naturally distributed in southern Russia, Mongolia and north-eastern China ( Sinitsyna et al. 2016; Sinitsyna and Friesen 2018). The existing records of this species in South Korea ( Choi and Oh 2010; Choi and Oh 2011) are all the result of misidentification of herbarium materials, the identity of which we have verified to be A. dumebuchum . Allium pseudosenescens is newly proposed as an additional synonym of A. senescens in this study.
