Related to magnoliid: Magnoliidae


Any of various flowering plants that are neither eudicotyledons nor monocotyledons, having embryos with two cotyledons and usually long, broad leaves and large flowers, and including magnolias, the avocado tree, and the cinnamon tree.

[New Latin Magnoliidae, name of the subclass including magnoliid species in several taxonomic systems : Magnolia, type genus of the subclass; see magnolia + -idae, suff. forming taxonomic names (from pl. of Latin -idēs, masculine patronymic suff., from Greek).]

1994a) and Mauldinia (Drinnan et al., 1990) are near Calycanthaceae and Lauraceae plus Hernandiaceae, respectively, in the magnoliid order Laurales, and Doyle and Endress (2014) confirmed that Monetianthus (Friis et al., 2009) is nested within Nymphaeales.
Given that the species is sister to the remaining member of the family, its presence in San Andres Island provides a significant value to increase the phylogenetic diversity in the Island, as the Canellaceae is one of the few magnoliid families in San Andres Island, along with the Annonaceae (2 spp.), the Lauraceae (4 spp.) and the Piperaceae (2 spp.) (Gonzalez et al.
This family is assigned to the clade Magnoliid according to the APG III system (2009) and according to Cronquist (1981) it was in subclass Magnoliidae, and order Magnoliales.
However, recent molecular and morphological analyses suggest that the family belongs to the magnoliid clade sensu APG II (2003), which includes several lineages that traditionally formed the sub-class Magnoliidae sensu Cronquist (1981).

Apart from magnoliid fossils having inner and outer staminodes, there is an abundance of eudicots having one whorl of sterile stamens.
This view of the potential utility of angiosperm wood anatomical data arose out of the great body of comparative anatomical data that has been amassed by numerous wood anatomists, most recently Sherwin Carlquist, who has made numerous contributions, particularly for many small but systematically significant families of magnoliid dicotyledons (see Carlquist 1988b, 1996 for extensive bibliographies).
For phylogenetic clade four groups were considered following the AGP III system (2009): monocots (commelinids), eudicots, Fabaceae as a special case of eudicots, and magnoliids.
Most of the major clades within angiosperms (e.g., monocots, magnoliids, eudicots) appear to have also small ancestral genomes, showing many possible instances of genome size increase and decrease in clades that occupy derived positions of the trees (Soltis et al., 2003; Leitch et al., 2005).
All large (informal) groups in angiosperms such as magnoliids, monocots, basal eudicots, rosids and asterids show a patchy image with both positive and negative observations.
