Type.

“Brasilien”, Glaziou 8004 (B†; lectotype, designated here: P! [P00753734]; isolectotypes: NY! [NY00246945], BR [BR000000694356, scan!], P! [P00753735]).

= Xyris augusto-coburgii Szyszyl. ex G.Beck., Itin. Princ. S. Coburgii 2: 94. 1888.

This name is a synonym of Xyris augusto-coburgii Szyszyl. ex G.Beck. Although cited in the protologue as deposited in B, the type material of X. glaziowii is no longer to be found there. Dr. Robert Vogt, curator of B, has confirmed that the type material of Xyris glaziowii probably disappeared as a result of World War II damage to the B herbarium. Duplicates of Glaziou 8004 at P, BR, NY, and a photograph at F were therefore examined with a view to selection of a lectotype. Smith and Downs (1968) indicated material deposited at P as the type. However, there are two sheets of Glaziou 8004 in this herbarium, and the sheet numbered P00753734 was chosen and designated here as the lectotype, because of its more complete label data, stating that the material is from São Paulo, Fazenda da Bocaina, near Cascatinha do rio Mambucabo, collected on February 11, 1876. The isolectotypes are: P00753735, NY00246945 and BR000000694356, which although from the same collection (Glaziou 8004), have incomplete label information. The BR sheet indicates that it originated from Rio de Janeiro, while the label data of the NY sheet indicates its origin as São Paulo, Bocaina, as in the lectotype.
