  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page.

Gilman2 Introduction Balfour Aralia is usually seen in its variegated form of glossy, light green leaves with irregular milk-white markings at its margins (Fig. 1). The stiffly upright growth habit, comprised of many stems, works well as a hedge or screen, or as a specimen. It grows nicely in a container for patio or terrace. The plant may thin out at the bottom as it grows older. Prune several of the older stems to the ground to encourage thicker foliage near the base.

  • Rice-Paper Plant Tetrapanax Papyrifer
    Rice-paper plant Tetrapanax papyrifer Family Araliaceae (ivy) Also known as Aralia papyifera, Fatsia papyifera Where is it originally from? South China, Taiwan What does it look like? An evergreen, rounded shrub or small tree (<8 m tall). Stems are densely covered in hairs when young, becoming more or less hairless with prominent leaf scars when older. Leaves are large and rounded heart-shaped, with toothed margins and (3-12) deep lobes (indented 1/3-2/3 of leaf radius). They are densely hairy on both surfaces when young, becoming more or less hairless above when mature, and are held on long leaf stalks (10-50 cm). Tiny white flowers (Autumn) are Photo: Carolyn Lewis held in white, woolly, ball-like clusters on a large, branched stem that extends beyond the foliage, and are followed by clusters of spherical black berries (3 mm diameter). Are there any similar species? Fatsia, Pseudopanax and Schefflera species are similar. Why is it weedy? Tolerates part shade. Vigorous growth rate. Grows into thickets by suckering. How does it spread? Spreads by suckers up to 2 m long. What damage does it do? Photo: Carolyn Lewis Can shade out native plants. Contact with foliage can cause skin rash. Which habitats is it likely to invade? Disturbed forest and shrubland, forest margins, stream banks, urban areas, roadsides and wasteplaces. What can I do to get rid of it? Dig out isolated plants or small patches, and remove root system when soil soft. What can I do to stop it coming back? Monitor the site and treat any regrowth.
