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. -

Insects of Macquarie Island. Introduction1
Pacific Insects 4 (4) : 905-915 December, 15, 1962 INSECTS OF MACQUARIE ISLAND. INTRODUCTION1 By J. Linsley Gressitt BISHOP MUSEUM, HONOLULU Abstract: Collections of land arthropods were made on Macquarie Island by J. L. Gres sitt and J. H. Calaby, 4-10 December 1960, and by Keith Watson, December 1960-Decem- ber 1961. This paper is a brief discussion of the geography and environment of Macquarie, introductory to the systematic papers describing the fauna. Watson, of the Australian Na tional Antarctic Research Expeditions, will later publish his general ecological studies, when the species are all identified. INTRODUCTION This paper is a brief description of the geography and environment of Macquarie Is land, as related to land arthropods. It is presented by way of introduction to the series of reports by various specialists on the land arthropod fauna of the island. The bulk of these reports immediately follow this article. (One Macquarie mite is discussed in the third of the preceding articles by Wallwork on Antarctic mites, and another is mentioned in his second article.) Others will appear in later issues, when they are completed. After publication of the bulk of these taxonomic reports, Keith Watson will publish his general report on the land arthropod fauna of Macquarie, incorporating his ecological studies on the fauna. Through the kindness of Mr. P. G. Law, Director of the Antarctic Division, Australian Department of External Affairs, I was permitted to join the Australian National Antarctic Research Expedition for the annual resupply trip to Macquarie Island in early December 1960. The operation, supported by the chartered Danish ice-breaker Magga Dan, was car ried on at Macquarie from 4th to lOth December. -
Plant Introductions to South Australia Prior to 1840 P.M
J. Adelaide Bot. Gard. 7(3): 217-231 (1985) PLANT INTRODUCTIONS TO SOUTH AUSTRALIA PRIOR TO 1840 P.M. Kloot 4 South Australian Department of Agriculture, G.P.O. Box 1671, Adelaide, S.A. 5001 tTh Abstract Selected historical data from 1802 to 1840 are presented to illustrate the extent of European plant introductions in both pre-colonial South Australia and the early years of official settlement. Some other effects such as land clearing and the early movement of weeds are briefly discussed. Introduction South Australia was proclaimed a colony of the British Crown on 28 December 1836 when the first Governor, Captain John Hindmarsh RN, hoisted the British flag at a ceremony on the shores of Gulf St Vincent. Prior to this date there had been a flurry of activity which had commenced on 27 July the same year when the advance party of settlers and surveyors had arrived on the "Duke of York" to lay the foundations for a Province of free settlers to be developed in accordance with the novel Wakefield Colonization Plan (Price, 1924). Apart from recounting the story of the earliest navigators, Flinders and Baudin, many historians make no mention of European involvement in South Australia prior to 1836 (e.g. Dutton, 1846; Sinnett, 1862; Pascoe, 1901). Passing references are sometimes made to the earlier presence of sealers and others on the off-shore islands but as they are not considered to have any direct bearing on the official settlement of the colony, they are dismissed as being of little importance in South Australian history. -

THE ALPINE FLORA of TIERRA DEL FUEGO by D. M. MOORE
Anal. Inst. Bot. Cavanilles 32 (2): 419-440 (1975) THE ALPINE FLORA OF TIERRA DEL FUEGO by D. M. MOORE This paper is dedicated to Prof. S, Rivas Goday on his 70th birthday. Introduction Since the first known collection of Fuegian plants, made along^ the NW coast of Tierra del Fuego by George Handisyd in 1690 (More- ton-Middleton, 1909; Gunckel, 1971), more than 200 collectors have contributed to our knowledge of the flora of this region (Moore and Goodall, unpub.). Because of the importance of shipborne expeditions, most of the earlier studies were confined to coastal areas and fuller information on the interior did not become available until the expe ditions of Nordenskjold (Dusen, 1900), Skottsberg (1916) and Roivai- nen (1954) during the late 19th and early 20th centuries. Since then there has, of course, been a continued accumulation of data on the flora and vegetation of Tierra del Fuego so that now, although many problems remain, the general characteristics are fairly clear. The mountainous regions of Tierra del Fuego are generally difficult of access and have uncertain and inclement weather so that even today many parts have not been visited by botanists. However, the travels of Alboff (1896, 1897), Dusen (1900), Gusinde (Skottsberg, 1926) and Skottsberg (1916) served to outline the general features of the alpine flora and these have been confirmed and amplified by more recent studies (Godley, 1960; Moore, 1969, 1970, 1971, etc; Moore and Goodall, 1973, 1974, etc.). In consequence, despite the inevitable lacunae in our knowledge, it seems appropriate to summarize current information on the alpine flora of Tierra del Fuego and this paper represents the first such attempt since that of Skottsberg (1916). -

Size Class Structure, Growth Rates, and Orientation of the Central Andean Cushion Azorella Compacta
Size class structure, growth rates, and orientation of the central Andean cushion Azorella compacta Catherine Kleier1, Tim Trenary2, Eric A. Graham3, William Stenzel4 and Philip W. Rundel5 1 Department of Biology, Regis University, Denver, CO, USA 2 Department of Mathematics, Regis University, Denver, CO, USA 3 Nexleaf Analytics, Los Angeles, CA, USA 4 Department of Computer Information Systems, Metropolitan State University, Denver, CO, USA 5 Department of Ecology and Evolutionary Biology, University of California, Los Angeles, CA, USA ABSTRACT Azorella compacta (llareta; Apiaceae) forms dense, woody, cushions and characterizes the high elevation rocky slopes of the central Andean Altiplano. Field studies of an elevational gradient of A. compacta within Lauca National Park in northern Chile found a reverse J-shape distribution of size classes of individuals with abundant small plants at all elevations. A new elevational limit for A. compacta was established at 5,250 m. A series of cushions marked 14 years earlier showed either slight shrinkage or small degrees of growth up to 2.2 cm yr−1. Despite their irregularity in growth, cushions of A. compacta show a strong orientation, centered on a north-facing aspect and angle of about 20◦ from horizontal. This exposure to maximize solar irradiance closely matches previous observations of a population favoring north-facing slopes at a similar angle. Populations of A. compacta appear to be stable, or even expanding, with young plants abundant.

A. 2 Department of Forest Resources & Stillinger Herbarium, College of Natural Resources, University of Idaho, P. O. Box 441133, Moscow, Idaho 83844-1133 U. S. A. 3 Author for correspondence ( [email protected] ) Communicating Editor: Javier Francisco-Ortega Abstract— Previous attempts to resolve relationships among the primary lineages of Campanulidae (e.g. Apiales, Asterales, Dipsacales) have mostly been unconvincing, and the placement of a number of smaller groups (e.g. Bruniaceae, Columelliaceae, Escalloniaceae) remains uncertain. Here we build on a recent analysis of an incomplete data set that was assembled from the literature for a set of 50 campanulid taxa. To this data set we first added newly generated DNA sequence data for the same set of genes and taxa. Second, we sequenced three additional cpDNA coding regions (ca. 8,000 bp) for the same set of 50 campanulid taxa. Finally, we assembled the most comprehensive sample of cam- panulid diversity to date, including ca. 17,000 bp of cpDNA for 122 campanulid taxa and five outgroups. Simply filling in missing data in the 50-taxon data set (rendering it 94% complete) resulted in a topology that was similar to earlier studies, but with little additional resolution or confidence. -
