  • Additions to the New Flora of Vermont
    Gilman, A.V. Additions to the New Flora of Vermont. Phytoneuron 2016-19: 1–16. Published 3 March 2016. ISSN 2153 733X ADDITIONS TO THE NEW FLORA OF VERMONT ARTHUR V. GILMAN Gilman & Briggs Environmental 1 Conti Circle, Suite 5, Barre, Vermont 05641 [email protected] ABSTRACT Twenty-two species of vascular plants are reported for the state of Vermont, additional to those reported in the recently published New Flora of Vermont. These are Agrimonia parviflora, Althaea officinalis , Aralia elata , Beckmannia syzigachne , Bidens polylepis , Botrychium spathulatum, Carex panicea , Carex rostrata, Eutrochium fistulosum , Ficaria verna, Hypopitys lanuginosa, Juncus conglomeratus, Juncus diffusissimus, Linum striatum, Lipandra polysperma , Matricaria chamomilla, Nabalus racemosus, Pachysandra terminalis, Parthenocissus tricuspidata , Ranunculus auricomus , Rosa arkansana , and Rudbeckia sullivantii. Also new are three varieties: Crataegus irrasa var. irrasa , Crataegus pruinosa var. parvula , and Viola sagittata var. sagittata . Three species that have been reported elsewhere in 2013–2015, Isoetes viridimontana, Naias canadensis , and Solidago brendiae , are also recapitulated. This report and the recently published New Flora of Vermont (Gilman 2015) together summarize knowledge of the vascular flora of Vermont as of this date. The New Flora of Vermont was recently published by The New York Botanical Garden Press (Gilman 2015). It is the first complete accounting of the vascular flora of Vermont since 1969 (Seymour 1969) and adds more than 200 taxa to the then-known flora of the state. However, the manuscript for the New Flora was finalized in spring 2013 and additional species are now known: those that have been observed more recently, that have been recently encountered (or re-discovered) in herbaria, or that were not included because they were under study at the time of finalization.

  • Duplication and Diversification in the APETALA1/FRUITFULL Floral
    Copyright 2003 by the Genetics Society of America Duplication and Diversification in the APETALA1/FRUITFULL Floral Homeotic Gene Lineage: Implications for the Evolution of Floral Development Amy Litt1 and Vivian F. Irish Molecular, Cellular, and Developmental Biology, Yale University, New Haven, Connecticut 06520-4108 Manuscript received March 21, 2003 Accepted for publication June 11, 2003 ABSTRACT Phylogenetic analyses of angiosperm MADS-box genes suggest that this gene family has undergone multiple duplication events followed by sequence divergence. To determine when such events have taken place and to understand the relationships of particular MADS-box gene lineages, we have identified APETALA1/FRUITFULL-like MADS-box genes from a variety of angiosperm species. Our phylogenetic analyses show two gene clades within the core eudicots, euAP1 (including Arabidopsis APETALA1 and Antirrhinum SQUAMOSA) and euFUL (including Arabidopsis FRUITFULL). Non-core eudicot species have only sequences similar to euFUL genes (FUL-like). The predicted protein products of euFUL and FUL- like genes share a conserved C-terminal motif. In contrast, predicted products of members of the euAP1 gene clade contain a different C terminus that includes an acidic transcription activation domain and a farnesylation signal. Sequence analyses indicate that the euAP1 amino acid motifs may have arisen via a translational frameshift from the euFUL/FUL-like motif. The euAP1 gene clade includes key regulators of floral development that have been implicated in the specification of perianth identity. However, the presence of euAP1 genes only in core eudicots suggests that there may have been changes in mechanisms of floral development that are correlated with the fixation of floral structure seen in this clade.

  • Green Factor Plant List 2010
    Revised December 2010 Seattle Green Factor Plant List Notes: ● All plants on this list are drought-tolerant once they are established unless comments indicate otherwise. ● Seattle Department of Transportations Right-of Way Improvement Manual establishes height limits for non-street-tree plantings in rights-of-way. Maximum plant height within 30 feet of an intersection (as measured from the corner of the curb) is 24 inches. Elsewhere in the right-of-way, plantings are allowed to be 30 inches tall. ● "Bioretention Zone" describes where plants can appropriately be used in bioretention systems such as swales and rain gardens. Zone 1 is the designation for plants that can be used in the flat bottoms of bioretention facilities: 1A refers to species that prefer soil saturation or shallow inundation for long durations, while Zone 1B refers to plants that can alternate between dry ands short-term saturated conditions. Zone 2 is the designation for plants best used at the well-drained slopes of bioretention facilities. All other species are appropriate for planting at the tops of bioretention areas.

  • Native Plants Recommended for Landscaping Woodland
    Native Plants Recommended for Landscaping From Cleveland Museum of Natural History’s website (www.cmnh.org) The plant list below includes an array of important native plant species that we recommend for landscaping. These plants provide animals with vital protection, food and nesting sites. The plant list is arranged in alphabetical order by common name. Each species can have several different common names, so when you are shopping for a specific plant we advise you to refer to it by its scientific name.

  • The Allegheny Pachysandra by MICHAEL A
    The Allegheny Pachysandra by MICHAEL A. DIRR and JOHN H. ALEXANDER III Repetition seems to be the rule with groundcovers for the same taxa are used repeatedly and few attempts have been made to educate the public or offer it alternative selections. Euonymus fortunei ’Colorata’, Hedera helix, Pachysandra terminalis and Vinca minor are the dominant offerings and comprise probably 50 to 60 percent of the total groundcover used in the East and Midwest. None of these groundcovers is without problems and in recent years Pachysandra terminalis, Japanese pachysandra, has been afflicted with Volutella pachysandrae, a fungal pathogen, that causes cankers and stem die- back. A severe infestation can literally devastate an established planting. Controls are available, but often by the time the home- owner recognizes that a problem exists, it is too late for effective treatment. The monoculture of trees (Ex: American elm) should have taught us something; however, the same type of mistake is being repeated with groundcovers. Above: Pachysandra terminalis. Although leaf arrangement is alternate, the nodes are so closely spaced that a rosette-like condition results. Below: Pachysandra terminalis. The specific epithet, terminalis, is derived from the position of the inflorescence. Photos: M. Dirr. 17 An American species, Pachysandra procumbens, Allegheny pachy- sandra, is one of the most handsome plants for groundcover use, yet is seldom seen in gardens or in commerce. This fact has been la- mented by other authorities (4, 6, 7, 8) and the species suffers a fate common to other quality plants: entrapment in the confines of an arboretum or botanic garden. Several reasons for the lack of visibility include limited publicity compared to its Japanese cousin, and the purported difficulty of propagation.

DC. (Apocynaceae) and Buxus sempervirens L. (Buxaceae), respectively, are strong and selective antit- rypanosomal agents, we have extended these studies to another plant, related to the latter—namely, Pachysandra terminalis Sieb. and Zucc. (Buxaceae). This species is known to contain aminosteroids similar to those of Holarrhena and structurally related to the aminocycloartanoids of Buxus. The dicholoromethane extract obtained from aerial parts of P. terminalis and, in particular, its alkaloid fraction obtained by acid–base partitioning showed prominent activity against Trypanosoma brucei Citation: Flittner, D.; Kaiser, M.; Mäser, P.; Lopes, N.P.; Schmidt, T.J.
