  • Woodland/Shade Gardening by Jimi Blake
    V OLUME 24, I SSUE 4 O CTOBER— DECEMBER 2015 Piedmont Chapter North American Rock Garden Society The Trillium Chapel Hill, Durham, Raleigh, NC Woodland/Shade Gardening By Jimi Blake Woodland plants are the brave plants that burst into flower in the spring lifting my spirit and encouraging me to start back to gardening in Hunting Brook, Co. Wicklow, Ireland. These plants are so important in the garden to extend the season of interest and brighten up a shady area. An expanse of deciduous woodland is not necessary to create a woodland garden, though it is a dream situation for this purpose but that shaded area in the corner of the garden where you dump the grass mowings can take on a whole new life, or by simply pruning a shrub to let more light under it will allow for your mini woodland garden. The other type of shade in lots of gardens is the shade creat- ed by walls, which is also suitable for growing woodland plants. In the wild, these plants flower under the dappled shade of the deciduous trees before the leaves shade out the woodland floor during the summer months. Generally the woodland plants finish flowering by early to mid sum- mer and form a ground cover of various shades of green. These plants are called spring ephemerals. Remember the secret of a good woodland garden is the preparation of the soil, as these areas can be quite dry in the summer with the roots of the trees or shrubs taking up the moisture. When I started the woodland gardens in Hunting Brook I cleared the weeds by hand and then dug over the soil and incorporated a mixture of leaf mould or garden compost, and very well rotted farmyard manure creating a delicious mixture for these woodland gems to grow well in.

Abstract Traditional knowledge of medicines on family Zingiberaceae were collected from South Western Maharashtra regions like Kolhapur, Satara, Ratnagiri, Sindhudurg Districts, during the year 2008 to 2010. The information related to plant species which are used to cure common ailments and disease by personal interviews with local people and herbalists.

  • Botanic Endeavour 250 Trail Botanic Endeavour Trail - 600M | Botanic Explorers Trail - 900M
    Botanic Endeavour 250 Trail Botanic Endeavour Trail - 600m | Botanic Explorers Trail - 900m Botanic Gardens Australia and New Zealand celebrates 250 years of the discovery of the flora of Australia’s east coast and New Zealand by western science in 1770 and over 40,000 years of traditional knowledge. Be an epic voyager for the day and discover some of the plants that Banks and Solander collected during their voyage along the east coast of Australia. Look out for the Botanic Endeavour 250 symbol to find what other plants were discovered during the voyage as you wander through the gardens. Botanic Endeavour 250 Our plants, our future Botanic Gardens and Arboreta throughout Australia and New Zealand (BGANZ) commemorate the anniversary ‘voyage of discovery’ onboard the barque Endeavour, during which Joseph Banks and Daniel Solander made a comprehensive collection of flora. Captain James Cook mapped the entire coastline of New Zealand in 1769 before traversing the east coast of Australia in 1770 from Point Hicks to Cape York. Pressings of over 520 new taxa unknown to western science were collected along the route up the east coast of Australia and these, along with thousands of botanical illustrations, somehow made it back to England in the face of shipwreck, waterlogging and the dank and humid conditions below decks. The rich abundance of diverse flora excited the botanic world and ultimately led to the settlement of the new colony. In Australia, 2020 marks the 250th anniversary of these discoveries. New Zealand celebrated this anniversary in 2019. Our Australian Indigenous heritage Prior to 1770, the Traditional Custodians of Australia lived in harmony with the land for over 40,000 years and discovered the ethnobotanic use for Australia’s native flora for food, medicine, tools, clothing and building materials.

  • Resolution of Deep Angiosperm Phylogeny Using Conserved Nuclear Genes and Estimates of Early Divergence Times
    ARTICLE Received 24 Mar 2014 | Accepted 11 Aug 2014 | Published 24 Sep 2014 DOI: 10.1038/ncomms5956 OPEN Resolution of deep angiosperm phylogeny using conserved nuclear genes and estimates of early divergence times Liping Zeng1, Qiang Zhang2, Renran Sun1, Hongzhi Kong3, Ning Zhang1,4 & Hong Ma1,5 Angiosperms are the most successful plants and support human livelihood and ecosystems. Angiosperm phylogeny is the foundation of studies of gene function and phenotypic evolution, divergence time estimation and biogeography. The relationship of the five divergent groups of the Mesangiospermae (B99.95% of extant angiosperms) remains uncertain, with multiple hypotheses reported in the literature. Here transcriptome data sets are obtained from 26 species lacking sequenced genomes, representing each of the five groups: eudicots, monocots, magnoliids, Chloranthaceae and Ceratophyllaceae. Phylogenetic analyses using 59 carefully selected low-copy nuclear genes resulted in highly supported relationships: sisterhood of eudicots and a clade containing Chloranthaceae and Ceratophyllaceae, with magnoliids being the next sister group, followed by monocots. Our topology allows a re-examination of the evolutionary patterns of 110 morphological characters. The molecular clock estimates of Mesangiospermae diversification during the late to middle Jurassic correspond well to the origins of some insects, which may have been a factor facilitating early angiosperm radiation. 1 State Key Laboratory of Genetic Engineering and Collaborative Innovation Center for Genetics and Development, Ministry of Education Key Laboratoryof Biodiversity Sciences and Ecological Engineering, Institute of Plant Biology, Institute of Biodiversity Science, Center for Evolutionary Biology, School of Life Sciences, Fudan University, 220 Handan Road, Yangpu District, Shanghai 200433, China. 2 Guangxi Institute of Botany, Guangxi Zhuang Autonomous Region and the Chinese Academy of Sciences, Guilin 541006, China.

If urbanisation is accompanied by a concomitant increase in shipping then this may also be a factor, i.e. increased propagule pressure of non-native species due to translocation beyond their native range via the hulls of ships and/or in ballast water. Singapore is potentially highly vulnerable to invasion by non-native marine species as its coastline comprises over 60% seawall and it is one of the world’s busiest ports. The aim of this study is to investigate the native, non-native, and cryptogenic molluscs found on Singapore’s seawalls.
