The Brassicaceae we taught here is the traditional Brassicaceae s.s., which is clearly monophyletic. But studies have suggested that Brassicaceae s.s. may be nested within the paraphyletic tropical family “Capparaceae”. If that’s true, then we should include “Capparaceae” into Brassicaceae s.l..

Malvaceae s.s. (Mallow family) The family Malvaceae is circumscribed broadly in your textbook, including four traditionally recognized families (i.e., Tiliaceae, Sterculiaceae, Bombacaceae, and Malvaceae s.s.). Since Malvaceae s.s. is still a monophyletic group and is the only one of the four families represented in our native flora. The family we are teaching here is Malvaceae s.s..

Hybridization and Polyploidization What is hybridization? Hybridization is the process of producing offspring of two organisms belonging to different varieties or species. –– the process to create hybrids. Why does hybridization matter? Well, nearly all of our major crops, livestock, pets, and ornamentals are hybrids between different species or varieties/races/strains.

Two species of the North American genus Oenothera are reported as aliens in the Czech Republic. A population of O. coronifera consisting of ca. 30 plants at various phenological stages, from ro- settes to flowering plants, was found in 2001 at the railway station in the town of Zliv, district of České Budějovice, S Bohemia. The species was probably introduced via the railway and is the first record of this species for the Czech Republic. A single plant of O. stricta, previously reported from the bank of the Vltava river in Prague, in 1825, was found as a weed in a private garden in the village of Vroutek, district of Louny, N Bohemia, in 2000. This is the second record of this species from the Czech Republic in 175 years.

  • Laurentian Mixed Forest Province, Cliff/Talus System Summary

    Laurentian Mixed Forest Province, Cliff/Talus System Summary

    CT Cliff and Talus System photo by M.D. Lee MN DNR Lake County, MN General Description Communities in the Cliff/Talus (CT) System are present on cliffs or talus slopes on steep- sided knobs, in river gorges, along lakeshores, and in other settings with sheer bedrock exposures. Often, cliffs and talus slopes are associated with one another because talus slopes are composed of rock fractured either from cliffs or from exposed bedrock on steep hillsides. The vegetation of CT communities is generally open. Lichens and moss- es are the dominant life forms, with vascular plants sparse or patchy because of scarcity of soil. In this classification, cliff communities are grouped by moisture and light regimes and by bedrock type, which are the major determinants of species composition. Cliff habitats range from warm and dry to cool and wet depending on cliff aspect, proximity to streams or lake shores, and presence of groundwater seepage on the cliff face. In the Laurentian Mixed Forest (LMF) Province, cliffs are formed most commonly of igneous bedrock, although cliffs on metamorphic rock are also common. Talus communities are classified according to amount of woody plant cover and moisture regime. In the LMF Province, CT communities are restricted mostly to the North Shore High- lands and Border Lakes subsections in NSU, where Precambrian bedrock is frequently at or just below the surface and topography is often rugged. Scattered cliffs are present in WSU and are likely in the Laurentian Uplands Subsection in NSU and the Littlefork- Vermilion Uplands Subsection in Northern Minnesota & Ontario Peatlands MOP, primar- ily along lakes and streams where water has exposed the underlying bedrock.

    A WEED REPORT from the book Weed Control in Natural Areas in the Western United States This WEED REPORT does not constitute a formal recommendation. When using herbicides always read the label, and when in doubt consult your farm advisor or county agent. This WEED REPORT is an excerpt from the book Weed Control in Natural Areas in the Western United States and is available wholesale through the UC Weed Research & Information Center (wric.ucdavis.edu) or retail through the Western Society of Weed Science (wsweedscience.org) or the California Invasive Species Council (cal-ipc.org). Ludwigia spp. Waterprimroses Family: Onagraceae Range: Primarily in the coastal states, Washington, Oregon and California; creeping waterprimrose is also found in Arizona and New Mexico. Habitat: Slow-flowing rivers, lake and reservoir margins, and in the shallow waters of canals and floodplains. Origin: Most species are native to South America. L. peploides ssp. peploides is native to California, Arizona, New Mexico, Ludwigia peploides Texas, and Louisiana; ssp. glabrescens (Kuntze) Raven is native to the central and eastern U.S.; and ssp. montevidensis (Spreng.) Raven is introduced from southern South America. L. peploides is sometimes sold as an aquarium or pond ornamental. Impacts: Dense stands degrade natural communities, reduce water quality and floodwater retention, and prevent effective mosquito control. Plants can develop a tangled mat of stems that can reduce water flow in irrigation channels and drainage ditches.

    VARIATION AND EVOLUTION IN SOUTH AMERICAN CLARKIA D. M. MOORE and HARLAN LEWiS Botany Department, University of Leicester and Botany Department, University of California, Los Angeles Received5.V.65 1.INTRODUCTION THEgenus Clarkia (Onagracee), currently considered to contain 36 species, is restricted to the western parts of North and South America (fig. i). The 35 North American species are distributed from Baja California to British Columbia (300N.to 48° N.), most of them occurring in California. The South American populations, which have a smaller though still considerable latitudinal spread (290 30' S. to 42030'S.), comprise a single variable species, Clarkia tenella (Cay.) H. and M. Lewis (Lewis and Lewis, within which four sub.. species have been recognised (Moore and Lewis, i 965b). Clarkia tenella is tetraploid, having n 34 (Hiorth, 1941; Raven and Lewis, 1959) and 2fl32 (Moore and Lewis, i965b). It is placed in section Godetia, together with seven North American species, and shows its closest affinities with the only tetraploid among these, C. davyi (Jeps.) H. and M. Lewis. A study of artificial hybrids between C. tenella and C. davji, together with pakeo-ecological evidence, led Raven and Lewis (i) to hypothesise that the two species were derived from a common tetraploid ancestor which had traversed the tropics by long-distance dispersal during or since the Late-Tertiary and given rise to the populations now comprising C. tenella. Detailed study of the variation within Clarkia tenella was made possible by a field trip to Chile and Argentina during 1960-61 and by subsequent experimental work at Leicester and Los Angeles.

    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.

    Master Gardener Corner: Hardy Hibiscus Originally Run Week of September 5, 2017

    This article is part of a weekly series published in the Batavia Daily News by Jan Beglinger, Agriculture Outreach Coordinator for CCE of Genesee County. Master Gardener Corner: Hardy Hibiscus Originally run week of September 5, 2017 Looking for a plant to add some color and bling to the late summer garden? Check out hardy hibiscus which is blooming now. The dinner plate size blooms bring a dramatic effect to the garden. Some of the new varieties, like ‘Midnight Marvel’ or ‘Kopper King,’ have reddish foliage for even more garden interest. Hardy hibiscus will also help attract hummingbirds and butterflies to your garden. The hibiscus family can be a bit confusing but they can generally be divided into four groups: hardy hibiscus, rose of Sharon, tropical hibiscus and all the other Hibiscus species. Hardy hibiscus usually refers to any of the North American native species (Hibiscus moscheutos, H. coccineus, H. dasycalyx, H. grandiflorus, H. laevis, and H. lasiocarpos and H. aculeatus). The native species tend to grow in or near marshes or swamps but they are tolerant to fluctuations in soil moisture. Flowers last for a single day with bloom colors varying from pure white, scarlet rose, lavender and shades of pink. The best known wild species is probably H. moscheutos commonly known as swamp rose mallow. It grows wild in wetland swamps from Ontario to Massachusetts and south to Florida, and west to Wisconsin and Tex as. It is hardy from USDA Zones 5 to 8. The shrubby plants have multiple upright stems growing up to 8 feet tall with a spread of 3 to 4 feet.
