Box 208106, New Haven, Connecticut 06520-8106, U.S.A. Broad-scale phylogenetic analyses of the angiosperms and of the Asteridae have failed to confidently resolve relationships among the major lineages of the campanulid Asteridae (i.e., the euasterid II of APG II, 2003). To address this problem we assembled presently available sequences for a core set of 50 taxa, representing the diver- sity of the four largest lineages (Apiales, Aquifoliales, Asterales, Dipsacales) as well as the smaller “unplaced” groups (e.g., Bruniaceae, Paracryphiaceae, Columelliaceae). We constructed four data matrices for phylogenetic analysis: a chloroplast coding matrix (atpB, matK, ndhF, rbcL), a chloroplast non-coding matrix (rps16 intron, trnT-F region, trnV-atpE IGS), a combined chloroplast dataset (all seven chloroplast regions), and a combined genome matrix (seven chloroplast regions plus 18S and 26S rDNA). Bayesian analyses of these datasets using mixed substitution models produced often well-resolved and supported trees.

Fall has arrived to the Pacific Northwest and that means the return of the cooler weather, but it also means so much Corokia more! The fall is a season of major transition. The spring and summer slowly change and they progress. The weath- er in spring slowly improves as the plants slowly grow and go through their life cycle. But in the fall, everything seems to fast-forward. We can have a cold snap, perhaps an early frost and everything changes drastically! I love the fall. got to have it....pg. 4 The colors are so bright and the air is crisp again. Unfortu- nately, the colors are here for only a short time! Fall, the season of dramatic changes! Bringing Houseplants In For us, this fall was about changes as well. This year we hosted our first Fall GardenPalooza. The past couple of years we have sponsored GardenPalooza: The Tour. This self-guided tour allowed people to travel on their own around the valley to visit garden centers, large and small. backyard....pg. 6 The problem was that the distances were very large and people spent most of their time driving between locations. So, along came changes! We approached the owners of Fir Corn Maze Point Farms, Jack and Jessica Romaine, and asked them if they would be interested in co-hosting a new fall event, and the Fall GardenPalooza was born on September 22nd.

The Island Rule and Its Application to Multiple Plant Traits
The island rule and its application to multiple plant traits Annemieke Lona Hedi Hendriks A thesis submitted to the Victoria University of Wellington in partial fulfilment of the requirements for the degree of Master of Science in Ecology and Biodiversity Victoria University of Wellington, New Zealand 2019 ii “The larger the island of knowledge, the longer the shoreline of wonder” Ralph W. Sockman. iii iv General Abstract Aim The Island Rule refers to a continuum of body size changes where large mainland species evolve to become smaller and small species evolve to become larger on islands. Previous work focuses almost solely on animals, with virtually no previous tests of its predictions on plants. I tested for (1) reduced floral size diversity on islands, a logical corollary of the island rule and (2) evidence of the Island Rule in plant stature, leaf size and petiole length. Location Small islands surrounding New Zealand; Antipodes, Auckland, Bounty, Campbell, Chatham, Kermadec, Lord Howe, Macquarie, Norfolk, Snares, Stewart and the Three Kings. Methods I compared the morphology of 65 island endemics and their closest ‘mainland’ relative. Species pairs were identified. Differences between archipelagos located at various latitudes were also assessed. Results Floral sizes were reduced on islands relative to the ‘mainland’, consistent with predictions of the Island Rule. Plant stature, leaf size and petiole length conformed to the Island Rule, with smaller plants increasing in size, and larger plants decreasing in size. Main conclusions Results indicate that the conceptual umbrella of the Island Rule can be expanded to plants, accelerating understanding of how plant traits evolve on isolated islands.

Each of the disjunctions appears to have resulted from north-to-south dispersal since the mid-Miocene; three are associated with such marked morphological and ecological change that some of the southern taxa (including Apostates) have been treated in distinct genera of uncertain relationship. Phyllotaxy within the Bahia alliance, however, evidently has been even more conservative evolutionarily than reflected by previous taxonomies, with alternate-leaved and opposite-leaved clades in Bahia sensu Ellison each encompassing representatives of other genera that share the same leaf arrangements. A revised taxonomic treatment of the Bahia alliance is proposed to recognize morphologically distinctive, monophyletic genera, including the critically endangered Apostates.

Various combinations of outgroups were assessed for their suitability and the effects of long branches and outgroups on tree topology were examined using RASA 2.4 prior to conducting phylogenetic analyses. RASA identified several potentially problematic taxa having long branches in individual data sets that may have obscured phylogenetic signal, but when data sets were combined RASA no longer detected long branch problems. tRASA provides a more conservative measurement for phylogenetic signal than the PTP and skewness tests. The separate matK and rbcL sequence data sets were measured as the chloroplast DNA containing phylogenetic signal by RASA, but PTP and skewness tests suggested the reverse. Nonetheless, the matK and rbcL sequence data sets suggested relationships within Cornales largely congruent with those suggested by the combined matK–rbcL sequence data set that contains significant phylogenetic signal as measured by tRASA, PTP, and skewness tests.

The Phytogeographical Affinities of the Pitcairn Islands – a Model for South-Eastern Polynesia?
Journal of Biogeography, 30, 1311–1328 The phytogeographical affinities of the Pitcairn Islands – a model for south-eastern Polynesia? Naomi Kingston1*, Steve Waldren2 and Una Bradley11Department of Botany, Trinity College, Dublin 2, Ireland and 2Trinity College Botanic Gardens, Palmerston Park, Dartry, Dublin 6, Ireland Abstract Aim To identify how the Pitcairn group relates biogeographically to the south-eastern Polynesian region and if, as a subset of the regions flora, it can then be used as a model for biogeographical analyses. Location The Pitcairn group (25°4¢ S, 130°06¢ W) comprises four islands: Pitcairn, a relatively young, high volcanic Island; Henderson, an uplifted atoll, the uplift caused by the eruption of Pitcairn; and two atolls, Ducie and Oeno. The remote location, young age and range of island types found in the Pitcairn Island group makes the group ideal for the study of island biogeography and evolution. Methods A detailed literature survey was carried out and several data sets were com- piled. Dispersal method, propagule number and range data were collected for each of the 114 species that occurs in the Pitcairn group, and environmental data was also gathered for islands in Polynesia. Analyses were carried out using non-metric multidimensional scaling and clustering techniques. Results The flora of the Pitcairn Islands is derived from the flora of other island groups in the south-eastern Polynesian region, notably those of the Austral, Society and Cook Islands. Species with a Pacific-wide distribution dominate the overall Pitcairn group flora. However, each of the islands show different patterns; Pitcairn is dominated by species with Pacific, Polynesian and endemic distributions, with anemochory as the dominant dispersal method (39.5%); Henderson is also dominated by species with Pacific, Polynesian and endemic distributions, but zoochory is the dominant dispersal method (59.4); Oeno and Ducie are dominated by Pantropic species with hydrochory as the most common dispersal method (52.9% and 100%, respectively).

Montpellier, 34398 Montpellier, France 2 AMAP, IRD, Herbier NOU, 98848 Nouméa, New Caledonia; [email protected] * Correspondence: [email protected] Abstract: The taxonomy of Argophyllum (Argophyllaceae) in New Caledonia is reviewed here. All names validly published in Argophyllum in this archipelago are discussed and lectotypified when necessary. A new species is described, Argophyllum riparium (The LSID for the name Argophyllum riparium is: 77216335-1) Pillon and Hequet sp. nov. Argophyllum grunowii and A. ellipticum are both species complexes in which several species previously recognized are included here as well. Seven species are recognized in New Caledonia: A. brevipetalum, A. ellipticum, A. grunowii, A. montanum, A. nitidum, A. riparium and A. vernicosum, all endemic. Leaf nickel content of A. riparium can exceed 1000 µg·g−1, which makes this species a nickel hyperaccumulator. Measurements with a handheld X-Ray Fluorescence (XRF) spectrometer confirmed that this was also the case for all other species from A. nitidum New Caledonia, except .
