New taxa and a key for Thryptomene (Myrtaceae: Chamelaucieae: Thryptomeninae)

Stapf (1924) published an infrageneric classification for Thryptomene, dividing the genus into five sections.Prior to his paper, only the typical section and sect.Paryphantha (Schauer) Kuntze had been recognised.A molecular framework and re-assessment of morphological characters are needed to determine how many of the previously named sections of Thryptomene should be recognised and whether any additional sections are needed.
