composition and distribution of leaf flavonoids in Hebe and leonoHebe plantaginaceae in new zealand 2 apertae occlusae and grandiflorae
New Zealand Journal of Botany, 2007Co-Authors: Kevin A. Mitchell, Kenneth R. Markham, Michael J. Bayly, Alison V. Kellow, Patrick J. Brownsey, P J GarnockjonesAbstract: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.

Composition and taxonomic distribution of leaf flavonoids in Hebe and LeonoHebe (Plantaginaceae) in New Zealand — 1. “Buxifoliatae”, “Flagriformes”, and LeonoHebe
New Zealand Journal of Botany, 2005Co-Authors: Kenneth R. Markham, Kevin A. Mitchell, Michael J. Bayly, Alison V. Kellow, Patrick J. Brownsey, Phil J. Garnock-jonesAbstract: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.

Variation in morphology and flavonoid chemistry in Hebe pimeleoides (Scrophulariaceae), including a revised subspecific classification
New Zealand Journal of Botany, 2003Co-Authors: Alison V. Kellow, Kevin A. Mitchell, Kenneth R. Markham, Michael J. Bayly, Phil J. Garnock-jonesAbstract:Abstract Variation in morphology and flavonoid chemistry is appraised in populations of Hebe pimeleoides. An infraspecific classification is proposed for H. pimeleoides, wherein two subspecies are recognised. Subspecies pimeleoides occurs from south‐east Nelson to central Otago, and is a subshrub of open places near lakes and streams, and of grassy slopes. Subspecies faucicola occurs in central Otago, and is a small, erect shrub growing on rocky outcrops in river valleys. There is some morphological overlap between the two subspecies, and two chromosome numbers (n = 20, n = 40) have been recorded in each. Subspecies faucicola is recognised on the basis of its distinctive habit and habitat, as well as correlated trends in other morphological characters (particularly flower colour) and leaf flavonoid content. A key to the subspecies of Hebe pimeleoides is provided.

iridoid glucosides in the genus veronica plantaginaceae from new zealand
Phytochemistry, 2017Co-Authors: Phillip Krollmoller, Katja Desiree Pedersen, Dirk C. Albach, Chrysoula Gousiadou, Charlotte Held Gotfredsen, Rilka Mladenova Taskova, Tetsuo Kokubun, P J Garnockjones, Soren Rosendal JensenAbstract:Abstract Four simple iridoid glucosides, three known esters of catalpol, seven esters of aucubin, and two phenylethanoids were isolated from Veronica hookeri (syn. Hebe ciliolata ; Plantaginaceae). Of these, none of four aromatic ( p -methoxybenzoyl, isovanilloyl, veratroyl, caffeoyl) 6- O -esters of aucubin and 6″- O -benzoyl mussaenosidic acid, had been reported from nature before. Similarly, three simple iridoid glucosides, two esters of 6- O -rhamnopyranosylcatapol, and two phenylethanoid glucosides, as well as 1- O -benzoyl-3-α-glucuronosylglycerol, and 1- O -β-benzoyl rutinoside were isolated from Veronica pinguifolia (syn. Hebe pinguifolia ). The compound 3″- O -benzoyl-2″- O -caffeoyl 6- O -rhamnopyranosylcatalpol had not been reported previously. The pattern of the structural features of the iridoid glucosides is overlaid onto the latest molecular phylogenetic framework of Veronica sects. Hebe and Labiatoides , and discussed in the context of evolutionary trends.

flavonoid profiles in the helioHebe group of new zealand veronica plantaginaceae
Biochemical Systematics and Ecology, 2008Co-Authors: Rilka Mladenova Taskova, Renee J Grayer, Tetsuo Kokubun, Ken G Ryan, P J GarnockjonesAbstract:Abstract The HelioHebe group of Veronica (sect. Hebe ) consists of five species occurring in the South Island of New Zealand. These species and a hybrid were analysed for their flavonoids. Five flavone glycosides were isolated and identified by NMR spectroscopy and three additional glycosides were detected by LC–UV–MS. Luteolin 7- O -, 3′- O - and 4′- O -glucosides and apigenin 7- O -glucoside were present in all six taxa investigated, 6-hydroxyluteolin glycosides were found in five and a luteolin caffeoylglycoside in four taxa, while a hypolaetin 7- O -glycoside was detected only in Veronica pentasepala . The 3′- O - and 4′- O -glucosides of luteolin are also common in other species of Veronica sect. Hebe (restricted to the Southern Hemisphere), but are rare in Northern Hemisphere species of Veronica and thus act as good chemotaxonomic markers for the section. The relatively simple flavonoid profiles found in the HelioHebe group are plesiomorphic and consistent with the group's status as sister to the Hebe clade. Based on the detected flavonoids, two groups could be distinguished within the HelioHebe clade: (1) Veronica hulkeana , Veronica lavaudiana and Veronica raoulii , characterised by luteolin caffeoylglycoside, and (2) V. pentasepala and Veronica scrupea , where this compound is replaced by a 6-hydroxyluteolin dihexoside.

botanical names in southern hemisphere veronica plantaginaceae sect detzneria sect Hebe and sect labiatoides
Taxon, 2007Co-Authors: P J Garnockjones, Dirk C. Albach, Barbara G BriggsAbstract:The classification of the Southern Hemisphere Veronica complex is discussed in the light of recent findings that these segregate genera are nested within the hitherto northern Veronica clade. In order to render Veronica monophyletic, we transfer Chionohehe, Derwentia, Detzneria, Hebe, Hebejeebie, HelioHebe, LeonoHebe, and ParaHebe to Veronica subgen. Pseudoveronica. Correct names are listed for all species in Veronica subgen. Pseudoveronica, according to the International Code of Botanical Nomenclature. Those species previously included in Derwentia together with other Australian species of Veronica are now classified in Veronica sect. Labiatoides, that in Detzneria is now classified in Veronica sect. Detzneria, and those in ChionoHebe, Hebe, HelioHebe, Leonohehe, and ParaHebe are now classified in Veronica sect. Hebe. Seventy-nine nomenclatural changes are provided: 61 new combinations (1 at section rank, 37 at species rank, 23 below species rank) and 18 new names (including 1 new name for a northern Veronica from the Caucasus).

Hebe arganthera (Scrophulariaceae), a new species from calcareous outcrops in Fiordland, New Zealand
New Zealand Journal of Botany, 2000Co-Authors: Phil J. Garnock-jones, Michael J. Bayly, William G. Lee, B. D. RanceAbstract:Abstract Hebe arganthera is described and illustrated. The new species is a shrub with dull green leaves, prominent leaf‐base scars, a narrow sinus in the leaf bud, opposite flowers at least basally, white anthers, and small seeds. It is confined to well‐lit sites on limestone and marble outcrops in Fiordland, southern New Zealand. We compare it with H. cockayneana, H. rupicola, and H. subalpina. It is known from three sites only and is considered to be vulnerable. We provide a key to all the species of Hebe known from Fiordland National Park.
