Boronia [section Boronella ] series Glabrae

Duretto & Heslewood, ser. nov.

Type: Boronia koniambiensis Däniker.

Differs from series Boronella by the glabrous branches ( v. pilose at nodes), opposite–decussate leave ( v. verticillate in whorls of 3), and petals being valvate in bud ( v. imbricate in bud).

Branches glabrous. Leaves opposite–decussate. Inflorescence a terminal cyme; bracts and bracteoles deciduous. Petals valvate in bud.

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 .
