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.
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.
2003) and sister to four magnoliid
groups (Canellales, Piperales, Magnoliales, Laurales) (Davis et al.
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).
, Hamamelid and Caryophyllid families.
Flowering plants, dicotyledons: Magnoliid
, hamamelid, and caryophyllid families.
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
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.
, 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.
