Biological Control of Two Ageratina Species (Asteraceae: Eupatorieae) in South Africa
Biological control of two Ageratina species (Asteraceae: Eupatorieae) in South Africa F. Heystek1*, A.R. Wood2, S. Neser1 & Y. Kistensamy1 1Agricultural Research Council-Plant Protection Research Institute, Private Bag X134, Queenswood, 0121 South Africa 2Agricultural Research Council-Plant Protection Research Institute, Private Bag X5017, Stellenbosch, 7599 South Africa Ageratina adenophora (Spreng.) R.M.King & H.Rob. and Ageratina riparia (Regel) R.M.King & H.Rob. (Asteraceae: Eupatorieae), originally from Mexico, are invasive in many countries. These plants produce thousands of wind- and water-dispersed seeds which enable them to spread rapidly and invade stream banks and moist habitats in areas with high rainfall. Two biological control agents, a shoot-galling fly, Procecidochares utilis Stone (Diptera: Tephri- tidae), and a leaf-spot fungus, Passalora ageratinae Crous & A.R. Wood (Mycosphaerellales: Mycosphaerellaceae), were introduced against A. adenophora in South Africa in 1984 and 1987, respectively. Both established but their impact is considered insufficient. Exploratory trips to Mexico between 2007 and 2009 to search for additional agents on A. adenophora produced a gregarious leaf-feeding moth, Lophoceramica sp. (Lepidoptera: Noctuidae), a stem-boring moth, probably Eugnosta medioxima (Razowski) (Lepidoptera: Tortricidae), a leaf-mining beetle, Pentispa fairmairei (Chapuis) (Coleoptera: Chrysomelidae: Cassidinae), and a leaf-rust, Baeodromus eupatorii (Arthur) Arthur (Pucciniales: Pucciniosiraceae) all of which have been subjected to preliminary investigations. Following its success in Hawaii, the white smut fungus, Entyloma ageratinae R.W. Barreto & H.C. Evans (Entylomatales: Entylomataceae), was introduced in 1989 to South Africa against A. riparia. Its impact has not been evaluated since its establishment in 1990 in South Africa. By 2009, however, A. -

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. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese -

We have never had so many problems in fitting the range of plants we have “on our books” into the available space! We always try and keep our lists “democratic” and balanced although at times our prejudices show and one or two groups rise to the top. This year we are offering an unprecedented range of calochortus in a multiplicity of sizes, colours and flower shapes from the charming fairy lanterns of C. albidus through to the spectacular, later-flowering mariposas with upward-facing bowl-shaped flowers in a rich tapestry of shades from canary-yellow through to lilac, lavender and purple. Counterpoised to these flashy dandies we are offering an assortment of choice muscari whose quiet charm, softer colours and Tulipa vvedenskyi Tecophilaea cyanocrocus Violacea persistent flowering make them no less effective in the winter and spring garden. Standouts among this group are the deliciously scented duo, M. muscarimi and M. macrocarpum and the striking and little known tassel-hyacith, M. weissii. While it has its devotees, many gardeners are unaware of the qualities of the large and diverse tribe of “onions”, known as alliums. -

Drought Tolerant Trees
Drought Tolerant Trees By Jessamyn Tuttle January 4, 2019 Tree choices for wet winters and dry summers Western Washington has long had a weather pattern of wet winters and dry summers, but if it seemed like the past couple of summers were warmer and dryer than usual, you're right. Many gardeners in the Pacific Northwest have noticed trees, both in their gardens and in the wilderness, wilting, getting leaf burn or insect infestations, even dying. Months without water can be fatal to many plants. When a plant dries out, the stomata on the leaves close up. Stomata allow transpiration, the loss of water through leaves, which helps the plant cool itself. Also, lack of water can increase nutrient deficiency. Eventually symptoms will manifest like leaf scorch on edges, wilted leaves, leaf drop and eventually twig dieback. A tree may survive drought stress after one season but die after several drought exposures. Younger, less established trees are more likely to die. And a drought stressed tree is more likely to succumb to insect damage or disease. The two-spotted spider mite, for example, loves hot and dry conditions. Even fungal diseases, often associated with damp conditions, may set into wood which was damaged years previously from drought. Despite this, the occasional dry spell isn't much of an issue, but the kind of drought we're starting to see may be getting worse. According to some climate projections, annual average global temperatures could rise between 1.5 and 7 degrees Celsius (2.7 to 12.6 degrees Fahrenheit), and it's expected that winters will be wetter, and summers will be dryer.
