rdf:langString Genera and Subclades

rdf:langString * Bossiaeeae ( Hutch 1964) * Genisteae subtribe Bossiaeinae (Benth. 1865) * Mirbelieae ( Polhill & Crisp 1982) * Podalyrieae subtribe Mirbeliinae (Benth. 1837)

rdf:langString 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. The Mirbelioids arose 48.4 ± 1.3 million years ago (in the early Eocene). 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. 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. 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. There has been a shift from bee pollination to bird pollination several times in this clade. Mirbelioids produce quinolizidine alkaloids, but unlike most papilionoids, they do not produce isoflavones. Many of the Mirbelioids have pseudoraceme inflorescences.
