AbstractEight epithets ofRigodium (R. araucarietiC. Müll.,R. argentinicumC. Müll.,R. brachypodium(C. Müll.) Par.,R. nano-fasciculatumC. Müll.exThér.,R. pendulumHerz.&Thér.,R. pseudo-thuidiumDus.,R. solutum(Tayl.) Par., andR. tamarixC. Müll), lectotypified here, are listed with their nomenclature and pertinent details involving the careful identification of type specimens and original material. ForRigodium solutum(Tayl.) Par., a specimen from Taylor's original herbarium may likely be the holotype but had not been indicated as such by Taylor, the original author. A conservative approach for this situation is taken here by designating this specimen as a lectotype.
