Type : "4*. Najas affinis, sp. nov. [...] Closely allied to N. Welwitschii, Rendle, from which it is distinguished by a less lax habit, the tuft-like densely leaved terminal branchlets, the more regularly toothed spreading firmer leaves, fimbriate leaf-sheath, and the pair of terminal outgrowths on the female spathe. Described from a plant in Herb. Cosson (Paris), collected by Leprieur; no locality is given, but it is doubtless from Senegal." [protologue].
