Notes.

This is a new, monospecific genus. The basionym name “ horrida ” is an adjective in the plural. There are examples of adjectives used as nouns in the names of genera. However, according to the recommendations in the Code (20 A. 1. [f, g]; Turland et al. (2018)), one should avoid adjectives as nouns and one must not use the epithet or derived form of the epithet of one of the species of the genus in question. The present synonym, Papaver horridum , is based on anthropogenically induced material from Australia ( Kadereit 1988 c) and would have priority in case Australian material is lifted to the species level by future studies. Therefore, a replacement name is a preferred alternative. Papaver sect. Horrida was monographed by Kadereit (1988 c), including synonyms and types.

Etymology.

Afropapaver refers to its relationship to Papaver and its strongly isolated occurrence in southernmost Africa ( Kadereit 1988 c).

Distribution.

Its distribution, as shown here in Fig. 4 , is based on Kadereit (1988 c), who concluded that the species is an early human introduction to Australia and is also synanthropic in Namibia.
