Nomenclatural Remarks and Typifications in the Genus Olea L. (Oleaceae)

TL;DR

This paper clarifies the classification of five names within the olive genus by assigning type specimens based on original materials and literature.

Contribution

The paper provides new typifications for five infraspecific taxa within Olea europaea, resolving their nomenclatural status.

Findings

O. europaea subsp. cerasiformis is lectotypified from a specimen in FI.

O. europaea var. maderensis is lectotypified from a specimen in BM collected in Madeira.

O. sylvestris is lectotypified from a Miller specimen preserved at BM.

Abstract

The typification of five names in the genus Olea (Oleaceae), viz. O. europaea subsp. cerasiformis, O. europaea var. maderensis, O. cuspidata, O. laperrinei, and O. sylvestris is discussed. These taxa are currently classified within O. europaea at the infraspecific rank. The designation of the types is based on the consultation of original material conserved in several herbaria and the literature cited in the respective protologues. The name O. europaea subsp. cerasiformis is lectotypified from a specimen preserved at FI. The name O. europaea var. maderensis (also named O. europaea subsp. maderensis or O. maderensis, and currently treated as a synonym of O. europaea subsp. cerasiformis) is lectotypified from a specimen collected by Lowe in Madeira and preserved at BM. The name O. cuspidata (currently O. europaea subsp. cuspidata) is lectotypifed from a specimen collected in India and preserved at K. The name O. laperrinei (currently O. europaea subsp. laperrinei) is lectotypifed from a specimen preserved at MPU and collected in the Sahara Desert (Ahaggar Mountains, Algeria). Finally, the name O. sylvestris (currently O. europaea var. sylvestris), wild olive, also named oleaster or acebuche (Spanish language), a wild relative of the olive tree, is lectotypified on a Miller specimen preserved at BM.
