Certain material of Stachytarpheta Vahl (Verbenaceae), mostly from the Caribbean coast of Central America (from Honduras to Panama), apparently related to S. calderonii Moldenke and S. indica (L.) Vahl, but consistently misidentified as S. jamaicensis (L.) Vahl, has been identified as S. friedrichsthalii Hayek. Examination of both syntypes of the latter name (Fendler 219, MO; Friedrichsthal 466, W) confirms that the calyx is more or less bilobed, versus 4-toothed in S. jamaicensis, under which S. friedrichsthalii has erroneously been placed in synonymy. One of the two sheets of Friedrichsthal 466 (W)—the one corresponding to Field Museum negative 34320—is chosen as the lectotype. Contrary to recent suggestion, the latest lectotypification of Verbena indica L. (on a portion of LINN 35.1) is found to be consistent with its protologue, and the consequent synonymy of S. angustifolia (Mill.) Vahl under S. indica is here accepted. Furthermore, it is suggested that S. friedrichsthalii may also be the correct name for some African material that has been included in S. indica (in much the same way S. friedrichsthalii has been found among Central American material of S. jamaicensis).
