Texas Trillium Arlington, Texas Ecological Services Field Office
U.S. FishU.S &. 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). -
"National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment. -

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. -
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. -

Large-Flowered Trilliums Coming up in Spring in Our Childhoo
Large-flowered Trillium or Common Trillium (Trillium grandiflorum) Large-flowered Trilliums Coming Up in Spring In our childhood the woods in late May were full of hundreds of large, waxy white flowers that covered the forest floor. Grandma in her German diary called these trilliums “wild lilies” and also commented that on May14th and 22nd in 1927 and again on May 22nd in 1940 these flowers were numerous and in full bloom. (Freckman, 1994) gave the earliest blooming dates as April 24th. Large-flowered Trillium Bud Opening Today, with more houses and lawns in the country, and fewer undisturbed woodlots those visions of white are less frequently seen. In addition, the White-tailed Deer population has steadily increased and their appetite for tasty trilliums has served to eliminate many stands of this beautiful plant. This is especially troublesome because once the leaves and flowers are plucked, the plant is likely to die. It can no longer produce food to send down to the roots so that it can come back another year. It still grows quite abundantly on the sloping bank along Billings Avenue in the Town of Medford, Wisconsin. Some sources say that deer do not like to graze on steep banks or inclines so that may be why those plants have escaped. We have a patch of trilliums that has grown larger each year in our lawn. Recently we have had to protect these trilliums from the deer that could wipe out the entire patch in a single night. Sometimes seeds from those plants, possibly transported by ants, have grown into new plants in the front lawn. -
Trillium, As an Indicator of Deer Density Hanover Biodiversity Committee October, 2017
[DRAFT v. 10] Trillium, as an indicator of deer density Hanover Biodiversity Committee October, 2017 Rationale for this Report Members of the lily family, such as Trillium and Clintonia, are among the favored foods of deer; 30 species of Trillium are found East of the Mississippi. The decline of these plants is mentioned in multiple publications1 as one key indicator of deer over-abundance. Red Trillium (Trillium erectum), also called ‘wake Robin’, found in the north-east and is (or was) fairly common in many Hanover forested neighborhoods. We suggest that monitoring this plant where it is (or once was) common demonstrates that deer density remains unsustainably high and future monitoring of the plant can help determine both the neighborhood density of deer and also serve as an indicator of change in deer density. Monitoring for this plant is easy, with just a small bit of training about the process. This report suggests a serious decline in biodiversity in Hanover over the past 15 years, as indicated by impact on red Trillium at three sites. We believe that with a focused increase in hunting pressure, this and other declining native plants might recover. Red Trillium is a frequent member of typical ‘rich mesic forests2’ plant communities found in Hanover; other plants often found nearby are Virginia waterleaf, blood root, wild ginger, foam flower, blue cohosh, and certain other members of the lily family. Besides aggressive deer browse, these communities are also threatened in varying degrees by invasive plants: garlic mustard, Dame’s rocket, wild parsnip, wild chervil and forget-me-not as well as the usual woody invaders. -

Understanding how various organisms respond to previous changes in climate could provide insight into how they may respond or adapt to the current changes. Conopholis americana has a broad distribution across eastern North America, covering both previously glaciated and unglaciated regions. In this study, we investigated the postglacial history and phylogeographic structure of this parasitic plant spe- cies to characterize its genetic variation and structure and to identify the number and locations of refugia. Methodology. Molecular data from 10 microsatellite markers and DNA sequences from the plastid gene/ introns (clpP) were obtained for 281 individuals sampled from 75 populations spanning the current range of the species in eastern North America and analyzed using a variety of phylogeographic methods. Distribution modeling was carried out to determine regions with relatively suitable climate niches for populations at the Last Glacial Maximum (LGM) and present. Pivotal results. We inferred the persistence of a minimum of two glacial refugia for C. americana at the LGM, one in north-central Florida and southern Alabama and another in the Appalachian Mountains near the southern tip of the Blue Ridge Mountains. -
