    Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE LILIACEAE de Jussieu 1789 (Lily Family) (also see AGAVACEAE, ALLIACEAE, ALSTROEMERIACEAE, AMARYLLIDACEAE, ASPARAGACEAE, COLCHICACEAE, HEMEROCALLIDACEAE, HOSTACEAE, HYACINTHACEAE, HYPOXIDACEAE, MELANTHIACEAE, NARTHECIACEAE, RUSCACEAE, SMILACACEAE, THEMIDACEAE, TOFIELDIACEAE) As here interpreted narrowly, the Liliaceae constitutes about 11 genera and 550 species, of the Northern Hemisphere. There has been much recent investigation and re-interpretation of evidence regarding the upper-level taxonomy of the Liliales, with strong suggestions that the broad Liliaceae recognized by Cronquist (1981) is artificial and polyphyletic. Cronquist (1993) himself concurs, at least to a degree: "we still await a comprehensive reorganization of the lilies into several families more comparable to other recognized families of angiosperms." Dahlgren & Clifford (1982) and Dahlgren, Clifford, & Yeo (1985) synthesized an early phase in the modern revolution of monocot taxonomy. Since then, additional research, especially molecular (Duvall et al. 1993, Chase et al. 1993, Bogler & Simpson 1995, and many others), has strongly validated the general lines (and many details) of Dahlgren's arrangement. The most recent synthesis (Kubitzki 1998a) is followed as the basis for familial and generic taxonomy of the lilies and their relatives (see summary below). References: Angiosperm Phylogeny Group (1998, 2003); Tamura in Kubitzki (1998a). Our “liliaceous” genera (members of orders placed in the Lilianae) are therefore divided as shown below, largely following Kubitzki (1998a) and some more recent molecular analyses. ALISMATALES TOFIELDIACEAE: Pleea, Tofieldia. LILIALES ALSTROEMERIACEAE: Alstroemeria COLCHICACEAE: Colchicum, Uvularia. LILIACEAE: Clintonia, Erythronium, Lilium, Medeola, Prosartes, Streptopus, Tricyrtis, Tulipa. MELANTHIACEAE: Amianthium, Anticlea, Chamaelirium, Helonias, Melanthium, Schoenocaulon, Stenanthium, Veratrum, Toxicoscordion, Trillium, Xerophyllum, Zigadenus.

Plants need an adequate amount of soil moisture for their optimum growth and yield. It plays very important role in building up plant metabolism. Soil amendment is one of the important methods that use to overcome water stress conditions. Biochar has been the most amendment, which used due to its potential role in many fields such as increasing microbial activity, better crop yield, C sequestration and increasing soil carbon. In the present study, two field experiments were established at the Experimental Farm of El-Kassasin Horticultural Research Station, Ismailia Governorate, Egypt, during the two successive seasons of 2015/2016 and 2016/2017.The objective of this research was to determine the effect of three soil moisture levels (W1=50, W2=35 andW3= 20% depletion of the available soil water) and three amounts of biochar (Bio1= 0.5, Bio2= 1and Bio3=1.5 ton biochar/fed) on growth and flowering characters as well as some biochemical characters of Dimorphotheca ecklonis (cape marigold) plant.

  • Winter Blooming Shrubs by RICHARD E
    Winter Blooming Shrubs by RICHARD E. WEAVER, JR. Winters in the eastern part of this country south of Washington, D.C. are seldom as unpleasant as they are here in the Northeast. Of course the temperatures there are less extreme, but for those of us who appreciate plants and flowers, the real difference is perhaps due to the Camellias. Blooming through the worst weather that January and February have to offer, these wonderful plants with their bright and showy blooms make winter something almost worth anticipating. Although there are some hopeful new developments through con- centrated breeding efforts, we in most of the Northeast still must do without Camellias in our gardens. Nevertheless, there are a sur- prising number of hardy shrubs, perhaps less showy but still charm- ing and attractive, that will bloom for us through the winter and the early days of spring. Some, such as the Witch Hazels, are foolproof; others present a challenge for they are susceptible to our capricious winters and may lose their opening flowers to a cold March. For those gardeners willing to take the chance, a few of the best early- flowering shrubs displayed in the border, or as the focal point in a winter garden, will help to soften the harshness of the season. Many plants that bloom in the early spring have their flowers per- fectly formed by the previous fall. Certain of these do not require a period of cold dormancy, and in mild climates will flower intermit- tently during the fall and winter. Most species, however, do require an environmental stimulus, usually a period of cold temperatures, before the buds will break and the flowers open.

  • Towards Resolving Lamiales Relationships
    Schäferhoff et al. BMC Evolutionary Biology 2010, 10:352 http://www.biomedcentral.com/1471-2148/10/352 RESEARCH ARTICLE Open Access Towards resolving Lamiales relationships: insights from rapidly evolving chloroplast sequences Bastian Schäferhoff1*, Andreas Fleischmann2, Eberhard Fischer3, Dirk C Albach4, Thomas Borsch5, Günther Heubl2, Kai F Müller1 Abstract Background: In the large angiosperm order Lamiales, a diverse array of highly specialized life strategies such as carnivory, parasitism, epiphytism, and desiccation tolerance occur, and some lineages possess drastically accelerated DNA substitutional rates or miniaturized genomes. However, understanding the evolution of these phenomena in the order, and clarifying borders of and relationships among lamialean families, has been hindered by largely unresolved trees in the past. Results: Our analysis of the rapidly evolving trnK/matK, trnL-F and rps16 chloroplast regions enabled us to infer more precise phylogenetic hypotheses for the Lamiales. Relationships among the nine first-branching families in the Lamiales tree are now resolved with very strong support. Subsequent to Plocospermataceae, a clade consisting of Carlemanniaceae plus Oleaceae branches, followed by Tetrachondraceae and a newly inferred clade composed of Gesneriaceae plus Calceolariaceae, which is also supported by morphological characters. Plantaginaceae (incl. Gratioleae) and Scrophulariaceae are well separated in the backbone grade; Lamiaceae and Verbenaceae appear in distant clades, while the recently described Linderniaceae are confirmed to be monophyletic and in an isolated position. Conclusions: Confidence about deep nodes of the Lamiales tree is an important step towards understanding the evolutionary diversification of a major clade of flowering plants. The degree of resolution obtained here now provides a first opportunity to discuss the evolution of morphological and biochemical traits in Lamiales.

  • Forsythia.Pdf
    A Horticulture Information article from the Wisconsin Master Gardener website, posted 18 April 2016 Forsythia, Forsythia spp. Forsythia is both the common and genus name of a group of deciduous fl ower shrubs in the olive family (Oleaceae) named after William Forsyth, a Scottish botanist who was at that time Director of the Royal Garden at Kensington and a founding member of England’s Royal Horticultural Society. The 11 or so species are primarily native to eastern Asia, with one species from Europe. The two quite variable species F. suspensa and F. viridissima were the fi rst to be brought from the Far East to Europe. Forsythia × intermedia is a hybrid of these species that was introduced in continental Europe Forsythia is a common landscape plant in the about 1880. Many Midwest. other crosses using the same two parents have been made so plants with this name can be quite variable. F. suspensa tends to have a widely open to drooping habit, but a more upright form found in China in 1861 was given the (incorrect) name F. fortunei. Other species discovered in the early 1900’s – F. giraldiana from China and F. ovata from Korea – as well as the European species F. europaea, have been used in 20th-century American crosses. Hardiness varies by species, with most in zones 5-8, but many of the hybrids are hardier than the parents, surviving in zones 4 or even 3. The unrelated white forsythia, Abeliophyllum distichum, has many of the same characteristics as forsythia, blooming White forsythia, Abeliophyllum about the same time, but with white fl owers.

Volume 14, No. 2 July 2013 Editorial Skippers in Slippers! by Robert Dirig HE FIRST WILD ORCHIDS I EVER SAW were Pink M Lady-slippers (Cypripedium acaule), which my family cherished in the Catskills. Later, my father showed me the Larger Yellow Lady-slipper (C. parviflorum, var. pubescens) along the Delaware River. But nowhere in that region did we find the other species that is pictured in all the guides — the great Showy Lady-slipper (C. reginae) that often grows in knee-high clumps, has leaves on its stems, and two or more gorgeous pink-and-white blooms per plant. I was in my thirties before I finally beheld this iconic wildflower near Ithaca, N.Y. More years passed, while I learned about its seepy fen habitats, with underlying marl that provided the damp limy situations required by this spectacular orchid. In the early 1980s, I started to compile yearly records of butterfly nectaring, a field habit that continues to the present. In all that time I have never observed a butterfly feeding at any kind of lady-slipper; the closest I came was finding a male Long Dash (Polites mystic) resting on a Showy’s flower at dusk (28 June edges of a beaver meadow, or on acidickind of 2000). Then on 21 June 2005, I noticed a dead male Hobomok Skipper (Poanes hobomok) trapped inside the lip of a Showy Lady-slipper at Cornell’s Eames Memorial Preserve, and within an hour found another at McLean Bogs Preserve.
