FishWildlife & Wildlife Service Service Texas Trillium Arlington, Texas Ecological Services Field Office Texas Trillium Trillium texanum Description Texas trillium belongs to the Liliaceae (lily) family and are rhizomatous herbs with unbranched stems. Trillium plants produce no true leaves or stems aboveground. Texas trillium has solitary white to pale pink flowers on a short stalk, situated above three bracteal leaves. It is the only trillium species in Texas with numerous stomata (specialized cells which open and close to regulate gas and water movement into/out of the plant) on Trillium pusillum var. texanum - (Photo Credit- Jason Singhurst) upper and lower surfaces of its bracts. Longevity is unknown, but one study fern (Woodwardia areolata), and showed that white trillium (Trillium green rein orchid (Platanthera grandiflorum) lives at least 30 years clavellata). based on estimates calculated from the number of constrictions on rhizomes. Conservation Although not listed as endangered or Habitat threatened by the State of Texas, Texas trillium habitat is characterized Texas trillium is ranked as a G2 by a shaded, forest understory. It (imperiled) by NatureServe and is flowers before full leaf-out of over ranked as a Sensitive Species by the story species and before being United States Forest Service. The Distribution overtopped by other herbaceous species is also listed on Texas Parks Texas trillium occurs across thirteen species. Texas trillium is found in the and Wildlife Department’s 2010 List counties in East Texas and into ecotone between riparian baygall and of the Rare Plants of Texas and as a northwestern Louisiana (Caddo sandy pine or oak uplands in the Species of Greatest Conservation Parish).

    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.

Back in the late yos the landscaping around my new house consisted of three magnolias: two M. x sorrlarrgeana, and a M. x loebneri 'MerrilL' At the time, these were the only magnolias gener- ally available at local nurseries. As I watched these magnolias bloom each spring, I became more intrigued with their beautiful Bowers and began driv- ing around Green Bay to observe and admire some of the established trees. My admiration for the genus contin- ued to grow each year as I began col- lecting more information about these magnificent plants. One summer I was in the Detroit area and I decided to call this magnolia expert, Phil Savage, that I had read so much about. I can vividly remember calling Phil from a telephone booth on Telegraph Road and finding mysell, an unknown amateur, talking to a magnolia expert who from the first made me feel like a lifelong friend.
  • How to Identify New Brunswick Violets

    How to Identify New Brunswick Violets

    How to Identify New Brunswick Violets Sponsored by the New Brunswick Botany Club Introduction : Violets are always exciting to find while walking in the field in early summer. They are so easy to identify as to their genus. However, most people will stop there, because they are not easy to identify at the species level - many minute characteristics must be examined...and they easily form difficult to describe hybrids. Approached in the right mix of adventurousness and humility, sorting out violets can be fun. However, should efforts end in exasperation, just keep in mind that the violets never read the botany books. (Choukas-Bradley 2004). In order to correctly identify violets the following features must be examined : these are stems, leaves and flowers. Above-ground stems are : a) acaulescent (stemless) b) caulescent (stemmed) In acaulescent species the rhizomes or stolons gives rise to a crown of basal leaves and flowers. Care should be taken to assess the position of leaves since some species (i.e. Viola adunca and Viola labradorica - caulescent species) may have very short (less than 1 cm) stems at flowering and may appear acaulescent. Below-ground stems are : a) slender rhizome b) stout rhizome c) taproot Rhizomes are slender (mostly 1 to 3 mm thick) and travel horizontally underground, or stout (mostly 4 to 6 mm thick) and are usually oriented vertically underground - these are the perennials. Annuals have a vertical, fibrous root known as a taproot. To evaluate a slender versus a stout rhizome in the field, just place your thumb and index vertically around the base of a plant, near the soil.

The examination will be conducted in English. Abstract Vinnersten, A. 2003. Tracing History. Phylogenetic, Taxonomic and Biogeographic Research in the Colchicum Family. Acta Universitatis Upsaliensis. Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 911. 33 pp. Uppsala. ISBN 91-554-5814-9 This thesis concerns the history and the intrafamilial delimitations of the plant family Colchicaceae. A phylogeny of 73 taxa representing all genera of Colchicaceae, except the monotypic Kuntheria, is presented. The molecular analysis based on three plastid regions—the rps16 intron, the atpB- rbcL intergenic spacer, and the trnL-F region—reveal the intrafamilial classification to be in need of revision. The two tribes Iphigenieae and Uvularieae are demonstrated to be paraphyletic. The well-known genus Colchicum is shown to be nested within Androcymbium, Onixotis constitutes a grade between Neodregea and Wurmbea, and Gloriosa is intermixed with species of Littonia. Two new tribes are described, Burchardieae and Tripladenieae, and the two tribes Colchiceae and Uvularieae are emended, leaving four tribes in the family. At generic level new combinations are made in Wurmbea and Gloriosa in order to render them monophyletic. The genus Androcymbium is paraphyletic in relation to Colchicum and the latter genus is therefore expanded.
  • Swing Through

    Swing Through

    Swing Through 20m Swing Through is an interactive agility garden that connects the user to Canada’s diverse landscape, as well as its major economic industry. The garden is a series of thirteen finished lumber posts that dangle from a large steel structure, creating “tree swings”. On the swings are climbing holds where visitors can use the holds to climb up and across the tree swings. Directly under the tree swings are thirteen colour-coordinated stumps that give the user an extra boost, if needed. The thirteen timber tree swings represent Canada’s ten provinces and three territories by using wood from the official provincial and territorial trees. Surrounding this structure of Canadian trees is a garden divided into thirteen sections displaying the native plants of each province and territory. This representative regional plantings encompassing the swings, creating a soft edge. 10m Swing Through allows visitors to touch, smell, and play with the various YT NT NU BC AB SK MB ON QC NL NB PE NS natural elements that make our country so green, prosperous and beautiful.
