Hedysarum triquetrum Linnaeus, Species Plantarum 2: 746. 1753.

"Habitat in India." RCN: 5504.

Lectotype (Fawcett & Rendle, Fl. Jamaica 4: 39. 1920; Pedley in Turland & Jarvis in Taxon 46: 472. 1997): Herb. Hermann 4: 18, No. 286, left specimen (BM-000628081).

Current name: Desmodium triquetrum (L.) DC. (Fabaceae: Faboideae).

Note: Fawcett & Rendle (Fl. Jamaica 4: 39. 1920) indicated Herb. Hermann material (BM) as type. Although there is material in more than one volume, it appears to have been part of a single gathering. Consequently, theirs is accepted as the first typification (Art. 9.15), with the choice subsequently restricted by Pedley. The choice of Herb. Linn. 921.20 (LINN) by Dy Phon (in Morat, Fl. Cambodge Laos Viêtnam 27: 52. 1994) post-dates that of Fawcett & Rendle.
