Hakea Groups/Sections etc.

@tonyrebelo asked me to list the species of Hakea and their Groups.

Introduction
George Bentham in 1870 (Bentham 1870) created 4 Sections and a number of Series for Hakea - but most of these are regarded as not Monophyletic. Robyn Barker and colleagues (Barker et al. 1999) in the Flora of Australia, developed a number of informal Groups to conveniently break the genus up into smaller chunks. These have some phylogenetic base and they discuss this in the Flora. They suggest that a formal infrageneric classification will be created once a phylogenetic study has been carried out. Since then there has been one phylogenetic study (Cardillo et al. 2017), but they created no formal Sections, etc. So, at the moment, there is no formal taxonomic infrageneric classification that can be added to iNaturalist.

Classification
The informal classification includes the following groups with their included species. Note there are lot of species - and only few have become invasive (NB Species not in Italics and with an * have been known to be invasive).

Thanks: The last reference states:
"Of the 24 non-monotypic informal taxonomic groupings within Hakea proposed by Barker et al. (1999), 9 are supported as monophyletic, but there is no support for the monophyly of the remaining groups. "
(there are 6 monotypic informal groups - i.e. with only one species).
