Echium Candicans DEPARTMENT OF PRIMARY INDUSTRIES Pride of Madeira Echium candicans Victorian Alert Weed Fact Sheet Plant biology Type of weed: Garden escape. Lifeform: Semi-woody biennial herb. Description: Stems: Pride of Madeira is a much-branched plant that grows to more than three metres high (PIER 2004; Webb et al 2004). The stem, fl owers and leaves of the plant are covered with fi ne, bristly, whitish coloured hairs (Spencer 2005). The species initially grows as a rosette at the base with leaves alternately arranged on the stem (Richardson et al 2006). Mature plants have longer stems with whitish papery bark and stout branches, with leaves growing more towards the stem’s apex (Bennett 2003).

Alternatives: Tower of jewels, star of Madeira, bugloss. Family: Boraginaceae. Flowers: E. candicans is a monocarpic shrub, Relevant relatives: There are over 40 species in the Echium meaning it only fl owers once before dying genus and 30 are listed as being weedy by the Global Compendium (Bennett 2003). Each branch can reach up to of Weeds (Randall 2001). Closely related plants to pride of Madeira 3.5 metres tall with the columnar fl ower spike include Echium wildpretii (tower of jewels) and Echium pininana reach lengths of 200-400 mm (Webb et al 2004). (giant viper’s bugloss), both of which are Victorian Alert Weeds. Each fl ower spike consists of thousands of tiny Common invasive relatives include Echium plantagineum (Paterson’s fl owers which range in colour from blue to violet curse). and in some ornamental varieties, white. Fruits: Following fl owering, each of the thousands of individual fl owers produce a four segmented fruit called a nutlet. When the fruits are ripe, they slipt into these four nutlets which can then release the seed. Seeds: A single 2-3 mm long seed is contained within each of the four nutlets, meaning each fl ower spike can produce hundreds and thousands of seeds (Webb et al 2004). The seeds have poorly developed wings that may help the seed to be wind dispersed over short distances (Lems 1960). Roots: The root system of E. candicans must be robust as it supports numerous long fl ower stems, some of which can reach 3.5 metres in length. Weed Alert!

Victorian Weed Risk Assessment: E. candicans is considered to be a high weed risk for Victoria because, like the related E. pininana, it has the ability to produce massive amounts of viable seed and has a tendency to form dense stands once it becomes established. E. candicans prefers to grow in forested and coastal areas and it threatens the native fl ora and fauna found within these sensitive ecosystems.

Seed bank/propagule persistence: There is limited information available on the seed of pride of Madeira. The close relative, E. pininana (giant viper’s bugloss), produces more than 200,000 seeds per fl owering event and usually has just one fl ower spike. Given E. candicans has numerous large fl ower spikes, we could assume that E. candicans may have even greater reproductive potential than its close relative.

    Well-known plants in each angiosperm order This list is generally from least evolved (most ancient) to most evolved (most modern). (I’m not sure if this applies for Eudicots; I’m listing them in the same order as APG II.) The first few plants are mostly primitive pond and aquarium plants. Next is Illicium (anise tree) from Austrobaileyales, then the magnoliids (Canellales thru Piperales), then monocots (Acorales through Zingiberales), and finally eudicots (Buxales through Dipsacales). The plants before the eudicots in this list are considered basal angiosperms. This list focuses only on angiosperms and does not look at earlier plants such as mosses, ferns, and conifers.

Box, 12619, Giza, Egypt. ABSTRACT Echium vulgare which is known as viper's bugloss is a species of flowering plant in the borage family of Boraginaceae. In this study, Echium vulgare was examined considering its phenolic and flavonoid contents, and the antioxidant activity of methanolic extract was investigated by the method called 2, 2-diphenylpicrylhydrazyl radical scavenging (DPPH) activity. High performance liquid chromatography (HPLC) was utilized to estimate the phenolic acids and flavonoid compounds. The data reported that the Echium vulgare methanol extract is a good source of total phenolic compounds, total flavonoids content and the antioxidant activity. The phenolic acids from Echium vulgare extract were estimated using HPLC, and the highest compounds were gallic acid, benzoic acid and isoferulic acid. Flavonoid compounds were the highest compounds in quercetrin and naringin. The results of the biological experiments illustrated that the concentrations 250 and 500mg/kg body weight from Echium vulgare had contained the polyphenols in the extract to maintain an ideal body weight, improve the complete blood picture, lipid profile and liver functions as Alanine (ALT) and Aspartate (AST) transaminoferase.

Other typically herbaceous dicotyledonous groups in which species of the Atlantic Islands are appreciably woodier than non-insular ones include Centaurea and Sonchus ( Asteraceae); Cheiranthus, Crambe, Descurainia, Parolinia, and Sinapodendron ( Brassicaceae); Convolvulus ( Convolvulaceae); and Plan­ tago ( Plantaginaceae). The tendency for Macaronesian species to be woodier than their main­ land relatives has naturally given rise to interpretations. The rosette shrubs of these islands are quite characteristic; such shrubs were termed "Feder­ buschgewachse" by Schenck ( 1907). These suggest to some workers her­ baceous groups in which the notably moderate climate of islands has per­ mitted continued growth; in these groups there is natural selection for plants that are of longer duration and increased woodiness, suiting the year-long growing season of such insular areas.

  • Exotic Species and Temporal Variation in Hawaiian Floral Visitation Networks
    Exotic Species and Temporal Variation in Hawaiian Floral Visitation Networks By Jennifer Lynn Imamura A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Environmental Science, Policy, and Management in the Graduate Division of the University of California, Berkeley Committee in charge: Professor George Roderick, Chair Professor Claire Kremen Professor Bruce Baldwin Spring 2019 Abstract Exotic Species and Temporal Variation in Hawaiian Floral Visitation Networks by Jennifer Lynn Imamura Doctor of Philosophy in Environmental Science, Policy, and Management University of California, Berkeley Professor George Roderick, Chair Many studies have documented the negative impact of invasive species on populations, communities, and ecosystems, although most have focused solely on antagonistic rather than mutualistic interactions. For mutualistic interactions, such as pollination, a key to understanding their impacts is how invasive species interact with native species and alter interaction networks. Chapter 1 explores the impacts of invasive species on islands, particularly in regard to plants, pollinators, and how these exotic species attach to existing pollination interaction networks. Island pollination networks differ from mainland counterparts in several important characteristics, including fewer species, more connectance, and increased vulnerability to both invasion and extinction. A progression of invasion has been previously proposed, through which supergeneralist native species

  • Impact of Introduced Honey Bees on Native Pollination Interactions of the Endemic Echium Wildpretii (Boraginaceae) on Tenerife, Canary Islands
    Impact of introduced honey bees on native pollination interactions of the endemic Echium wildpretii (Boraginaceae) on Tenerife, Canary Islands Yoko L. Dupont *, Dennis M. Hansen, Alfredo Valido, Jens M. Olesen Department of Ecology and Genetics, University of Aarhus, Ny Munkegade Building 540, Aarhus C 8000, Denmark Abstract The aim of this study was to investigate effects of introduced honey bees (Apis mellifera) on native pollination interactions of Echium wildpretii ssp. wildpretii in the sub-alpine desert of Tenerife. We selected two study populations, one dominated by honey bees, while the other was visited by many native insects. During peak activity period of insects, nectar was nearly completely de- pleted in flowers of the first, but not the latter population. Thus, a high abundance of honey bees may have suppressed visitation by native animals due to exploitative competition. Honey bees stayed longer and visited more flowers on the same inflorescence than native bees, thus potentially promoting self-pollination of the plants. Level of seed set and viability was similar in the two study populations. However, we cannot rule out long-term changes in genetic population structure due to changes in gene-flow patterns caused by foraging behaviour of honey bees vs. native flower-visitors. Keywords: Disruption of native mutualisms; Interspecific competition; Apis mellifera; Conservation 1. Introduction are often found to be less efficient pollinators compared to native flower-visiting animals (Schaffer et al., 1983; In recent years the impact of introduced honey bees Taylor and Whelan, 1988; Westerkamp, 1991; Paton, (Apis mellifera L.) on native flora and fauna has been 1993; Vaughton, 1996; Gross and Mackay, 1998; Han- much debated.

  • Laurisilva of Madeira Portugal
    LAURISILVA OF MADEIRA PORTUGAL The Laurisilva of Madeira is the largest surviving relict of a virtually extinct laurel forest type once widespread in Europe. It is still 90% primary forest and is a centre of plant diversity, containing a unique suite of rare and relict plants and animals, especially endemic bryophytes, ferns, vascular plants, animals such as the Madeiran long-toed pigeon and a very rich invertebrate fauna. COUNTRY Portugal NAME Laurisilva of Madeira NATURAL WORLD HERITAGE SITE 1999: Inscribed on the World Heritage List under Natural Criteria ix and x. STATEMENT OF OUTSTANDING UNIVERSAL VALUE The UNESCO World Heritage Committee adopted the following Statement of Outstanding Universal Value at the time of inscription: Brief Synthesis The Laurisilva of Madeira, within the Parque Natural da Madeira (Madeira Natural Park) conserves the largest surviving area of primary laurel forest or "laurisilva", a vegetation type that is now confined to the Azores, Madeira and the Canary Islands. These forests display a wealth of ecological niches, intact ecosystem processes, and play a predominant role in maintaining the hydrological balance on the Island of Madeira. The property has great importance for biodiversity conservation with at least 76 vascular plant species endemic to Madeira occurring in the property, together with a high number of endemic invertebrates and two endemic birds including the emblematic Madeiran Laurel Pigeon. Criterion (ix): The Laurisilva of Madeira is an outstanding relict of a previously widespread laurel forest type, which covered much of Southern Europe 15-40 million years ago. The forest of the property completely covers a series of very steep, V-shaped valleys leading from the plateau and east-west ridge in the centre of the island to the north coast.
