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

"Habitat in India." RCN: 5495.

Lectotype (Merrill in Philipp. J. Sci., C, 5: 92. 1910): [icon] " Onobrychis Madraspat. Nummulariae folio, Ornithopodii siliquis " in Petiver, Gazophyl. Nat.: 41, t. 26, f. 4. 1702-1709.

Current name: Indigofera nummulariifolia (L.) Alston ( Fabaceae: Faboideae).

Note: Specific epithet spelled “nummularifolium” in the protologue.

Although Fawcett & Rendle (Fl. Jamaica 4: 40. 1920), and many later authors, treated Herb. Hermann material (BM) as the type, this choice is pre-dated by Merrill’s 1910 designation of a Petiver illustration as type.
