Nomenclatural reappraisal of the Macroptilium gracile (Leguminosae) species complex

Abstract

The controversy regarding the status of the Macroptilium gracile species complex has been elucidated by the authors of this paper; nevertheless, some nomenclatural issues regarding the naming of the newly established variety have been found. In the present contribution, we discuss some nomenclatural aspects concerning the valid publication of the name Macroptilium gracile var. subcoriaceum (Benth.) Berlingeri, M.B.Crespo & Calles. After considering different nomenclatural evidence, the latter varietal name is to be considered superfluous and therefore, we establish a new combination (i.e., Macroptilium gracile var. longepedunculatum).
