COMMENT

Pottia apoda Durieu ex Besch. nom. nud. was reported by Bescherelle (1882) based on a sample of Durieu’s herbarium, indicating that it looks like an impoverished form of Pterygoneurum cavifolium . Its identity has not been revised since. Pterygoneurum ovatum var. perraldieri (Besch.) Wijk & Margad. was described from Algeria as Pottia cavifolia var. perraldieri Besch. (Bescherelle 1882) . It was reported by Bescherelle (1882), Corbière (1905), andJelenc (1955a) from Constantine, Djebel Mansourah, and by Corbière (1905) from environs de Constantine, Chettabah. Its identity has not been reassessed since its description (Ros et al. 2013).
