The Mirbelioids are an informal subdivision of the plant family Fabaceae that includes the former tribes Bossiaeeae and Mirbelieae. They are consistently recovered as a monophyletic clade in molecular phylogenies. [1] [3] [4] [5] [6] [7] [8] [9] The Mirbelioids arose 48.4 ± 1.3 million years ago (in the early Eocene). [10] Members of this clade are mostly ericoid ( sclerophyllous) shrubs with yellow and red ('egg and bacon') flowers found in Australia, Tasmania, and Papua-New Guinea. [11] [12] The name of this clade is informal and is not assumed to have any particular taxonomic rank like the names authorized by the ICBN or the ICPN. [2] Members of this clade exhibit unusual embryology compared to other legumes, either enlarged antipodal cells in the embryo sac or the production of multiple embryo sacs. [3] [4] [13] [14] There has been a shift from bee pollination to bird pollination several times in this clade. [15] Mirbelioids produce quinolizidine alkaloids, [16] but unlike most papilionoids, they do not produce isoflavones. [17] Many of the Mirbelioids have pseudoraceme inflorescences. [18]
The Mirbelioids have been circumscribed to include the following genera: [5] [19]
It has been proposed that many of these genera be subsumed into Pultenaea. [21] [22] [23]
