Didymelaceae
Encyclopedia
Didymelaceae is a family
of flowering plants. The family has been recognised by a fair number of taxonomists, at least over the past few decades.
The APG II system
of 2003 does not recognise the family as such, the plants involved being included in the family Buxaceae
. However, APG II does allow the option of segregating this family, as an optional segregate; it is then unplaced as to order and left among the basal lineages of the eudicots
.
This represents a slight change from the APG system
, of 1998, which firmly did recognised the family, with the same placement.
The family consists of a single genus only, Didymeles
, with probably two species of evergreen trees, restricted to Madagascar
and the Comoro Islands

Family (biology)
In biological classification, family is* a taxonomic rank. Other well-known ranks are life, domain, kingdom, phylum, class, order, genus, and species, with family fitting between order and genus. As for the other well-known ranks, there is the option of an immediately lower rank, indicated by the...

APG II system
The APG II system of plant classification is the second, now obsolete, version of a modern, mostly molecular-based, system of plant taxonomy that was published in April 2003 by the Angiosperm Phylogeny Group. It was a revision of the first APG system, published in 1998, and was superseded in 2009...
