Abstract A taxonomic revision of Hebe and Leonohebe
in New Zealand has involved studies of both plant morphology and
flavonoid chemistry. This paper is the first in a series that
summarises the composition and taxonomic distribution of leaf
flavonoids in the two genera. It describes the flavonoid glycosides
encountered in a survey of c. 700 samples (from throughout the two
genera), and outlines the distribution of flavonoids in species of
“Buxifoliatae” and “Flagriformes” (informal infrageneric groups of Hebe)
and in Leonohebe. The structures of 83 of the most commonly
occurring flavonoids are identified (or tentatively identified); also
recorded are 32 unidentified or partly identified flavonoids that are
generally less common. Twenty-eight of the flavonoid glycosides have
not previously been reported in other plant genera. Most species, in
each of “Buxifoliatae”, “Flagriformes”, and Leonohebe, can be
distinguished by their flavonoid profiles, generally through possession
of unique combinations of compounds.
