Type: Boronia koniambiensis Däniker.

A monotypic series confined to the Koniambo Massif, north-eastern Grande Terre, New Caledonia.

Etymology

The series epithet is derived from the Latin glabrus alluding to the glabrous branches, which is one of the features that distinguishes this species from all other species in section Boronella .
