(Goodeniaceae) Growing in the Manawatu District of New Zealand0 aObservations on Two Coastal Ecotypes of Selliera radicans Cav Go  a541-5500 v123 aMorphologically distinct forms of Selliera radicans Cav. growing on silty flats in the estuary of the Rangitikei River and on sand plains in the dunes c. 1.3 km to the south are described.Small pieces of S. radicans rhizome were collected from these two areas and planted in pots containing either sand from the sand plain site, sandy-silt from the estuary site, or a standard potting mix. All were grown for 10 months under identical conditions in a glasshouse. Measurements of leaf dimensions at the beginning and end of the experiment support the view that the two forms are genetically distinct, and can be regarded as ecotypes. A clone of the sand plain form was grown for 34 months in a garden, and the resulting changes in leaf form are illustrated.Several other species have dwarf forms on the sand plains, and it is tentatively suggested that ecotypic differentiation has occurred in these species also. 1 aOgden, John  uhttps://juncaginaceae.myspecies.info/node/26702168nas a2200181   4500008004100000245004400041210004400085300001200129490000700141520161200148653001801760653005001778653004501828653002801873100001701901700001801918856005001936       1975                        eng d00aVascular Plants of the Auckland Islands0 aVascular Plants of the Auckland Islands  a665-7200 v133 aAll vascular plants recorded from the Auckland Islands are listed, with an indication of the validity of the records and the status and distribution of each taxon. Those which need further collections are noted. Recent voucher specimens are cited. New records are: Acaena anserinifolia, Blechnum chambersii, Hymenophyllum armstrongii, Triglochin striatum, Juncus articulatus, Ranunculus hirtus, Capsella bursa-pastoris, Epilobium alsinoides subsp. atriplicifolium, Haloragis aggregata, Galium propinquum, Abortanella rosulata, Taraxacum magellanicum, Hebe salicifolia, and Limosella lineata. Species not collected for a long time but now confirmed are: Hymenophyllum bivalva, H. dilatatum, H. minimum, Juncus bufonius, Corybas rivularis, Carex ternaria, Holcus lanatus, Puccinellia antipoda, and Trifolium repens.A total of 257 taxa are listed, 43 of which we recommend be omitted from the extant flora, either because they were reported in error, are of uncertain taxonomic status, or have died out.Twelve species of uncertain taxonomic status are listed, plus a further 10 species for which  a variety has also been reported from the Auckland Islands. Thirty percent of the 187 indigenous taxa appear to be restricted in their distribution within the Auckland Islands. These are discussed in relation to patterns of botanical collecting, transoceanic dispersal, vegetation history, and disturbance by humans.New Zealand taxa which may be adventive to the Auckland Islands are listed, and other adventive species are tabled with their history of collection. Patterns of spread and extinction are discussed.10aJuncaginaceae10aNew Zealand, Auckland Islands, Enderby Island10asouthern limit in the New Zealand region10aTriglochin, T. striatum1 aJohnson, P N1 aCampbell, D J  uhttps://juncaginaceae.myspecies.info/node/18000560nas a2200121   4500008004100000245003900041210003800080300001200118490000700130520023400137100001700371856005000388       1976                        eng d00aBinucleate pollen in Triglochin L.0 aBinucleate pollen in Triglochin L  a115-1160 v143 aPollen of Triglochin striatum (Juncaginaceae) and Aponogeton distachyus (Aponogetonaceae) is binucleate at anthesis, in contrast to the trinucleate pollen previously recorded from the Alismatales-Najadales line of Monocotyledons.1 aGardner, R O  uhttps://juncaginaceae.myspecies.info/node/118
