Abstract The distribution of flavonoid glycosides in five
species and three putative variants of
Phyllocladus is examined to
evaluate its taxonomic significance. The status of all five species is
supported by their respective accumulation of major constituents and the
regular presence/absence of quantitatively minor components. There are
reasonable grounds, based on flavonoid complement, for the recognition of the
North Cape variant of
P. trichomanoides,
and possibly also the
lowland variant of
P. alpinus, as distinct taxa. The chemical status of
the eastern North Island variant of
P. alpinus is less certain at this
stage and requires further study.
