14. Amaranthus hypochondriacus L., Sp. Pl.: 991. 1753 ≡ Amaranthus hybridus subsp. hypochondriacus ( L.) Thell. in Mém. Soc. Natl. Sci. Nat. Math. Cherbourg 38: 204. 1912. – Lectotype (designated by Townsend 1985: 25): Herb. Linn. No. 1117.24 ( LINN).

Remarks — This species evolved by domestication in SW North America within the native range of its presumed wild progenitor Amaranthus powellii . It is widely cultivated as an ornamental plant, pseudocereal and fod- der crop in tropical to warm-temperate regions worldwide ( Bayón 2015: 289). In most parts of continental and insular Greece it is observed as a casual escape near its places of cultivation; although it was given as naturalized by Arianoutsou & al. (2010), there is no reliable evidence for this. It is also known to occur in Albania ( Pils 2016: 21, P11) and Bulgaria ( Assyov & al. 2012: 66). Records taken from floristic literature with determinations based on the taxonomic concept of Greuter & al. (1984: 47) are considered doubtful unless corroborated by revised herbarium specimens, in order to exclude confusion with A. cruentus , A. hybridus , A. powellii or A. quitensis . Rejection of the name A. hybridus as ambiguous in favour of A. hypochondriacus ( Greuter 1981; Greuter & al. 1984) is not advisable because both names are clearly typified ( Townsend 1974; 1985) and have been used in the correct sense in recent basic floras and monographs ( Raus 1997; Bayón 2015; Iamonico 2015a, 2015b).
