Note

The rather pedantic reasons for the controversy over the name of this species are as follows. All hinges on whether Thouars meant to cite Aublet or not. Aublet cites Plumier, “ Phaseolus maritimus fructu duro ”, as mentioned above. Lamarck based his name on Plumier, Plukenet's Phaseolus maritimus purgans also mentioned above and also on Rheede's Catu-Tsjandi, Hort. Malabar. 8:83, t.43 (1688). Thouars did not cite Aublet but cited Plukenet, Rheede and also Rumphius's “Cacara laut”, Herb. Amboin. 9:390 (1747), the latter being a different species. It may thus be argued that Thouars did not transfer Aublet's epithet but produced a new name which bars any later transfer of Aublet's epithet under the homonym rule. Plukenet cited Rheede, and Commelin's Phaseolus maritimus indicus, Hort. Med. Amstel.:276 (1689); Sloane cited both Plukenet's and Commelin's names as synonyms of his own Phaseolus maritimus rotundifolius, Cat. Pl. Jam. 1:69 (1696), and Sloane's name was cited by Browne as a synonym of his Dolichos maritimus repens, which as mentioned above is itself in turn partly the basis of Swartz's name accepted here. Obviously as Sauer points out all these names are linked together and I sympathize with his use of maritima but the editors of this Flora wish the rules to be followed and in any case rosea is in common use in Africa.
