Tasmannia Lanceolata
ASPECTS OF LEAF AND EXTRACT PRODUCTION from Tasmannia lanceolata by Chris Read, B. Agr.Sc. Tas.

University of Tasmania HOBART March 1996 This thesis may be made available for loan and limited copying in accordance with the Copyright Act 1968 University of Tasmania HOBART March 1996 Abstract This thesis examines several aspects of the preparation, extraction and analysis of solvent soluble compounds from leaf material of Tasmannia lanceolata and reports a preliminary survey of extracts of some members of the natural population of the species in Tasmania. A major constituent of these extracts, polygodial, was shown to be stored within specialised idioblastic structures scattered throughout the mesophyll, and characterised by distinctive size and shape, and a thickened wall. The contents of these cells were sampled directly, analysed and compared with the composition of extracts derived from ground, dry whole leaf. This result was supported by spectroscopic analysis of undisturbed oil cells in whole leaf tissue. In a two year field trial, the progressive accumulation of a number of leaf extract constituents (linalool, cubebene, caryophyllene, germacrene D, bicyclogermacrene, cadina-1,4 - diene, aristolone and polygodial) during the growth flush was followed by a slow decline during the subsequent dormant season.

Reconstructing the Basal Angiosperm Phylogeny: Evaluating Information Content of Mitochondrial Genes
55 (4) • November 2006: 837–856 Qiu & al. • Basal angiosperm phylogeny Reconstructing the basal angiosperm phylogeny: evaluating information content of mitochondrial genes Yin-Long Qiu1, Libo Li, Tory A. Hendry, Ruiqi Li, David W. Taylor, Michael J. Issa, Alexander J. Ronen, Mona L. Vekaria & Adam M. White 1Department of Ecology & Evolutionary Biology, The University Herbarium, University of Michigan, Ann Arbor, Michigan 48109-1048, U.S.A. [email protected] (author for correspondence). Three mitochondrial (atp1, matR, nad5), four chloroplast (atpB, matK, rbcL, rpoC2), and one nuclear (18S) genes from 162 seed plants, representing all major lineages of gymnosperms and angiosperms, were analyzed together in a supermatrix or in various partitions using likelihood and parsimony methods. The results show that Amborella + Nymphaeales together constitute the first diverging lineage of angiosperms, and that the topology of Amborella alone being sister to all other angiosperms likely represents a local long branch attrac- tion artifact. The monophyly of magnoliids, as well as sister relationships between Magnoliales and Laurales, and between Canellales and Piperales, are all strongly supported. The sister relationship to eudicots of Ceratophyllum is not strongly supported by this study; instead a placement of the genus with Chloranthaceae receives moderate support in the mitochondrial gene analyses. Relationships among magnoliids, monocots, and eudicots remain unresolved. Direct comparisons of analytic results from several data partitions with or without RNA editing sites show that in multigene analyses, RNA editing has no effect on well supported rela- tionships, but minor effect on weakly supported ones. Finally, comparisons of results from separate analyses of mitochondrial and chloroplast genes demonstrate that mitochondrial genes, with overall slower rates of sub- stitution than chloroplast genes, are informative phylogenetic markers, and are particularly suitable for resolv- ing deep relationships.

Turner Fairfield, Pett Level Road, Winchelsea Beach, East Sussex TN36 4ND, U.K. [email protected] ABSTRACT. The names of plant taxa authored by H.N. Ridley from the orders of primitive angiosperms are enumerated. A total of 157 taxa across 11 families (Annonaceae, Aristolochiaceae, Chloranthaceae, Illiciaceae, Lauraceae, Magnoliaceae, Monimiaceae, Nymphaeaceae, Piperaceae, Trimeniaceae and Winteraceae) and seven orders (Austrobaileyales, Canellales, Chloranthales, Laurales, Magnoliales, Nymphaeales and Piperales) are listed with synonyms and accepted names. The types are listed for those taxa that Ridley described. Lectotypes are designated for 37 taxa. Melodorum breviflorum Ridl. (Annonaceae) is transferred to Fissistigma, and two Ridley species in Piperaceae that are later homonyms are provided with new names: Peperomia kerinciensis I.M.Turner for Peperomia villosa Ridl. (1917, nom. illegit. non P. villosa C.DC. (1866)) and Piper angsiense I.M.Turner for Piper venosum Ridl. (1925, nom. illegit. non P. venosum (Miq.) C.DC. (1869)). Keywords. Austrobaileyales, Canellales, Chloranthales, Laurales, Magnoliales, Nymphaeales, Piperales, primitive angiosperms, Ridley Introduction This paper continues an intermittent series on the plant taxa named by Henry Nicholas Ridley (1855–1956). The three parts published to date (Turner & Chin 1998a, b; Turner 2000), dealt with the pteridophytes, gymnosperms and Zingiberales, respectively. The focus shifts to the primitive angiosperms in the current paper. Ridley described many plant species. Among the primitive angiosperm orders there are numerous examples which are enumerated in this paper.

Tasmannia Lanceolata.14-06-17
Tasmannia lanceolata Tasmannia lanceolata (syn. Drimys lanceolata). Family: Winteraceae Common names: Mountain pepper, Tasmanian pepperberry, Cornish pepper leaf (UK). Tasmannia lanceolata Mt Buffalo, Vic (E.Bennetto) Tasmannia lanceolata is a shrub native to woodlands and cool temperate rainforest of south-eastern Australia. The shrub varies from 2 to 10 m high. The aromatic leaves are lanceolate to narrow-elliptic, 4–12 cm long, and 0.7– 2.0 cm wide, with a distinctly pale undersurface. Stems are quite red in colour. The small cream or white flowers appear in summer and are followed by black, globose, two-lobed berries 5–8 mm wide, which appear in autumn. There are separate male and female plants. Originally described by French botanist Jean Louis Marie Poiret, it gained its current name in 1969 by A.C. Smith. It had been known for many years as Drimys lanceolata. Uses The leaf and berry are used as a spice, typically dried. Mountain pepper was used as a colonial pepper substitute. More recently, it has become popularised as bushfood condiment. It can be added to curries, cheeses, and alcoholic beverages. It is exported to Japan to flavour wasabi. Dried T. lanceolata berries and leaves have strong antimicrobial activity against food spoilage organisms. It also has high antioxidant activity. Used in colonial medicine as a substitute for Winter's bark (stomachic) , it was also used for treating scurvy. It can be grown as a garden plant, and its berries attract birds. Currawongs are among those which feed on them. It can be propagated from cuttings or seed, and can grow in a well-drained acidic soil with some shade, but is sensitive to Phytophthora cinnamomi.

Section 2, Module 2: Phylogeny and Its Applications – Student Handout
Phylogeny for VCE Biology Section 2, Module 2: Phylogeny and its applications – Student Handout The Mountain Pepper is a well-known plant species native to Australia. It is distributed from Tasmania to Victoria and Southern New South Wales, having been extensively used by Aboriginal people for its food and medicinal properties. During colonial times, the plant was promptly identified as an efficient source of vitamin C, used to treat scurvy, and was a popular spice for cooking. Today, Mountain Pepper has commercial use, being imported to Japan for constituting one of the ingredients that makes wasabi. The figure below shows a short section of the Angiosperm clade, which includes the order to which Mountain Peppers belong. Tasmannia lanceolata, Mount Donna Buang, Victoria, Australia Image source: Wikimedia commons Phylogeny of ancient spice clade Magnoliids Figure 1: Current phylogenetic tree of Angiosperms, depicting the Magnoliids and all of its Orders. Due to its valuable properties, there is an interest in identifying other plant species that might be similar to the Mountain Pepper. Knowing that related species tend to present similar properties, a scientist wants to find which plant previously understudied would most resemble the Mountain Pepper. For the investigation, the scientist chooses Nut Meg, Bay leaves, Black pepper and the Giant Water Lily looking to find whether they group together based on their chemical and molecular similarity. The plant species chosen by the scientist and their respective uses are summarised in Table 1. Table 1: Well-known Angiosperms across the globe and native to Australia Common name Uses Species Order Nut meg Spice Myristica fragrans Bay leaves Spice Laurus nobilis Black pepper Spice Piper nigrum Australian native pepper Spice/ herbal Tasmannia remedy lanceolata Giant water lily Ornamental Victoria amazonica Given that the Orders of all plant species shown in Table 1 are present in Figure 1, you are to find which Order corresponds to which plant.

Aspects of Developing Tasmannia Lanceolata for Commercial Extract Production
Aspects of developing Tasmannia lanceolata for commercial extract production Matthew Deas Wilson, B. Agr.Sc. (Hons) Submitted in fulfilment of the requirements for the degree of Doctor of Philosophy School of Land and Food University of Tasmania June 2015 Declarations This thesis contains no material which has been accepted for a degree or diploma by the University or any other institution, except by way of background information and duly acknowledged in the thesis, and to the best of my knowledge and belief no material previously published or written by another person except where due acknowledgement is made in the text of the thesis, nor does the thesis contain any material that infringes copyright. Matthew Wilson This thesis may be made available for loan and limited copying and communication in accordance with the Copyright Act 1968. Matthew Wilson I Abstract Essential oils crops offer high value, low volume end products for export. Tasmannia lanceolata is currently commercially utilised for its plant extract on a small scale, but the consistency of yield and quality potentially offered by plantation production of the species has the capacity to significantly increase the size of the industry. Early attempts at small scale plantation production highlighted the need to understand the ecophysiology of the species. Climatic and nutritional effects on the growth and plant extract yield and quality of the species were investigated in both glasshouse and field trial conditions. Experiments were conducted on growth responses to manipulated levels of light, temperature, wind and nutrients (with separate experiments focusing specifically on the macronutrients N, P and K and fertiliser rate respectively).
