Abstract A taxonomic revision of Hebe and
Leonohebe
in New Zealand has involved studies of plant morphology and flavonoid
chemistry. This paper is the second in a series that summarises the
composition and taxonomic distribution of leaf flavonoids in the two
genera. It outlines the distribution of flavonoids in species of
"Apertae", "Occlusae", and "Grandiflorae" (informal infrageneric groups
of Hebe). Presence/absence data are presented for 85 flavonoids
from 377 samples of 42 species (as well as some samples of uncertain
taxonomic placement). Flavonoid variation within and between species is
illustrated using a series of ordination analyses. Most species in each
of "Apertae" and "Grandiflorae" and many in "Occlusae" can be
distinguished by their flavonoid profiles, generally through possession
of unique combinations of compounds.
