Four Australian species of Veronica sens. lat. are newly described and illustrated; lectotypes are selected for other species and synonyms. In V. 'sect. Derwentia' (Raf.) B.G.Briggs (in Garnock-Jones et al. submitted) we informally recognise three clades: the Derwentia clade, the V. formosa clade and the V. calycina clade. A second species of the V...

The taxonomic status of 3 species of the genus Limnophila viz., L. micrantha (Benth.) Benth., L. glandulifera Philcox and L. repens (Benth.) Benth. were examined. L. micrantha and L. glandulifera is found to be conspecific with L. repens. Hence, these 2 names are reduced here into the synonymy of the earlier name, L. repens (Benth.) Benth.
New information has extended the known range of Callitriche pulchra Schotsm. (Plantaginaceae) to Cyprus. This, combined with a survey of populations on the island of Gavdos off the S coast of Crete, shows that it is less threatened than previously thought. Updated information is presented here on the distribution, status and ecology of this species...
A new species Veronica hongii , from western Hubei Province, Central China is described and illustrated. The species is morphologically similar to V. henryi Yamazaki, but mainly differs in the glabrous plant, except pedicels, broadly ovate leaf blades, glandular-pubescent pedicels, obovate calyx lobes, smaller corolla, broadly ovate capsule and muc...

... Albach & Chase (2001), , , Mabberley (2008), Albach (2008) and Albach & Meudt (2010) also presented arguments for including all the southern genera in a wide and monophyletic circumscription of Veronica. Briggs & Ehrendorfer (2006a), Jensen et al. (2008), Mabberley (2008, Meudt (2008), Taskova et al. (2008Taskova et al. ( , 2012, Humphries & Linder (2009), Hughes et al. (2010, Pufal et al. (2010), Lee et al. (2011), Heenan (2012, Lord et al. (2013), and the Landcare Research herbarium and databases (see Breitwieser et al. 2012) have followed this wider circumscription. Nevertheless, other New Zealand botanists have explicitly rejected an inclusive monophyletic circumscription of Veronica (Gardner 2007;Thorsen 2007;Norton & Molloy 2009;de Lange 2011a;Mark 2012;de Lange et al. 2013;Wilson 2013). ...
The nature, value and relative importance of different lines of evidence for deciding the circumscription and rank of genera are examined and discussed. First, I argue that the circumscriptions of genera (and higher taxa) should always be monophyletic, preferably with strong support from independent evidence. Second, the rank of genus is decided on more subjective grounds, but several criteria are helpful: phylogeny should be recoverable from the classification hierarchy, genera should be distinctive, ranks should not be redundant and familiar names should be retained if other criteria are met. I then apply these criteria to an evaluation of the circumscription and rank of 59 New Zealand endemic genera of seed plants accepted in two recent checklists. Fifteen genera (25.4%) were rejected and 16 (27.1%) are considered equivocal. However, my lower estimate almost certainly underestimates endemism at genus rank because the circumscriptions of several genera not evaluated here, such as Pachycladon, could change in the future to become endemic. One new combination is made: Sonchus novae-zelandiae (Hook.f.) Garn.-Jones, although work in progress by others is likely to lead to several more.
... Although no formal intrasectional classification has been published so far, several authors have delimited groups within the Australian Veronica species either by assigning species to different sections (Römpp 1928;Bentham 1846) or genera (e.g. Briggs and Ehrendorfer 1992;Heads 1994), which are all now completely subsumed under the name Veronica, or by giving informal names (Briggs and Ehrendorfer 2006). The latter authors designated all somewhat woody species to the Derwentia clade, the herbaceous species to the Calycina clade and V. continua and V. formosa to the Formosa clade. ...
... The next branches in the ITS tree lead to V. notabilis and to the Formosa clade of Briggs and Ehrendorfer (2006), together with V. lithophila and V. nivea. The coherence of the Formosa clade has been questioned above; however, V. formosa and V. nivea also associate in the plastid tree. ...
... The base number x = 19 appears either homoplasious (Fig. 2) or transitional to x = 18 (Fig. 3). Briggs and Ehrendorfer (1992) originally considered that V. lithophila shared with Parahebe the distinctive corolla-lobe folds shown in a photograph purported to be of newly opened flowers of that species; however, later (Briggs and Ehrendorfer 2006) they reported that the photographed plant had been misidentified and that V. lithophila has flat lateral corolla lobes. ...
Phylogenetic analyses of DNA-sequence data have revealed that the southern hemisphere species of Veronica are derived from within the northern hemisphere Veronica clade. Previous analyses focussed on the species in New Zealand and included at maximum 7 of 23 species of section Labiatoides from Australia. In the present study, we used nuclear ribosomal-ITS and plastid ndhF-rpl32-spacer sequence data of all species currently recognised in Australia to analyse phylogenetic patterns. Most importantly, herbaceous species from coastal calcareous sands or limestone habitats do not form a clade with those from shady, moist forest habitats, as formerly believed, but seem to be independently derived from woody species. Incongruence between results from nuclear- and plastid-DNA markers suggest hybridisation to be an important factor in the evolution of the group. Our sample of V. parnkalliana included alleles similar to V. decorosa and V. novae-hollandiae at both loci, which suggests a hybrid origin.
... The species and infraspecific names are listed under their sectional names below. In making new names and new combinations, we have provided only basionyms; additional synonymy and typification is provided by Bayly & Kellow (2004, 2006 for names previously treated under Hebe and Leonohebe; Briggs & Ehrendorfer (1968, 1992, 2006b for Australian species previously treated under Parahebe and Derwentia; Garnock-Jones (1993b) for names previously treated under Heliohebe; Garnock-Jones & Lloyd (2004) for New Zealand species previously treated under Parahebe; and van Royen (1972Royen ( , 1983 and van Royen & Ehrendorfer (1970) both for New Guinea species previously treated under Parahebe and Detzneria. Typification of the names of species previously treated under Chionohebe (Briggs & Ehrendorfer, 1976) is provided herein. ...
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 Chionohebe, 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, Leonohebe, 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).
... Information on the New Zealand taxa is given by Dawson (2000) while Bayly and Kellow (2006) provide a revised and updated list of chromosome numbers for species formerly included in Hebe or Leonohebe. New taxa and taxonomic notes on these Australian taxa are presented by Briggs and Ehrendorfer (2006) in this issue of Telopea. Chromosome numbers for most of the Australian species formerly included in Derwentia or Parahebe have been reported already by Briggs and Ehrendorfer (1992); references to these reports are included here, giving the names and authorities (as in Garnock-Jones et al. submitted), now that they will be included in an enlarged Veronica. ...
New records of chromosome numbers are presented for eleven Australian species of Veronica sens. lat. Reference is also given to records previously published for ten species that have been referred to Derwentia, Parahebe or Chionohebe, but that are now included in a widely circumscribed Veronica. The species formerly included in Derwentia, Parahebe or Chionohebe exhibit secondary base numbers of x = 21, 20 or 19, whereas those formerly retained in Veronica have x = 18 (or 17). For the species formerly referred to Detzneria, from New Guinea, we present only a very approximate count of 2n = 38-42 which, however, differs from the previous report of 2n = 48.
Study of the Plantaginaceae for the Flora Mesoamericana project has resulted in five lectotypifications, a new combination in Rhodochiton, and the discovery of a new species of Tetranema from Honduras. This species, Tetranema michaelfayanum, is described here, a key to the species of Tetranema is provided, and the T. roseum complex is discussed.
Fourteen collections representing type or possible type material of Australian plants, housed in the Economic Botany Collection at the Royal Botanic Gardens, Kew, are documented and illustrated. They appear to have been overlooked by taxonomists. One, Hicksbeachia pinnatifolia F.Muell., may be all that remains of the type material. The others are: Adansonia gregorii F.Muell., Casuarina decaisneana F.Muell., Eucalyptus dichromophloia F.Muell., Eucalyptus megacarpa F.Muell., Eucalyptus ptychocarpa F.Muell., Helicia sayeriana F.Muell., Kentia belmoreana C.Moore & F.Muell., Kentia canterburyana C.Moore & F.Muell., Kentia mooreana F.Muell., Livistona alfredii F.Muell., Musa banksii F.Muell., Paederota densifolia F.Muell., Pandanus forsteri C.Moore & F.Muell.
The genus Cycas is reviewed for India. Eight species are treated, one of them published for the first time (Cycas indica). The species are placed within an infrageneric classification previously outlined. Distributions of all taxa are mapped, and a key to species is provided.
The snow hebes, formerly comprising the genus Chionohebe, are here included within Veronica (Plantaginaceae). The five species (including two subspecies) of snow hebes recognised here are cushions or subshrubs that occur exclusively in high-elevation habitats of Australia and the South Island of New Zealand. Species delimitation among the cushion snow hebes is very difficult because of the reduced pulvinate habit, solitary flowers and few gross-morphological characters useful for identification. To address species limits, investigate intraspecific patterns and revise the taxonomy of the snow hebes, morphological analyses were conducted and the results compared with previously published molecular phylogenetic data. Ordination and clustering analyses of morphological data showed some taxonomic structuring; however, species clusters were not widely separated from one another. Morphological and amplified fragment length polymorphism (AFLP) data show that the cushion species are clearly distinguished from the subshrub species, V. densifolia (F.Muell.) F.Muell. Among the four cushion species (V. chionohebe Garn.-Jones, V. ciliolata (Hook.f.) Cheeseman, V. pulvinaris (Hook.f.) Cheeseman, V. thomsonii (Buchanan) Cheeseman), the distribution of leaf trichomes is important for species identification, particularly when used in conjunction with ovary vestiture, capsule size, and/or seed size. One new combination V. ciliolata subsp. fiordensis (Ashwin) Meudt is proposed, and V. uniflora Kirk is treated as a naturally occurring hybrid V.  uniflora (V. densifolia  V. thomsonii). Complete synonymies, descriptions, illustrations and range maps are provided for each species, as well as a key to all species and a discussion of putative hybrids.
