  • "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.

  • Class Monocotyledonae
    ACORUS/ACORACEAE 1077 CLASS MONOCOTYLEDONAE Plants usually herbaceous—in other words, lacking regular secondary thickening (except Palmaceae, Smilacaceae, most Agavaceae, and a few Poaceae); seedlings usually with 1 seed leaf or cotyledon; stems or branches elongating by apical growth and also by growth of basal por- tion of internodes; leaves when present alternate, whorled, basal, or rarely opposite, elongating by basal growth (readily seen on spring-flowering bulbs whose leaf-tips have been frozen back); leaf blades usually with parallel or concentrically curved veins, these unbranched or with inconspicuous, short, transverse connectives (leaves net-veined or with prominent midrib and spreading side-veins parallel with each other in Alismataceae, Araceae, Smilacaceae, Marantaceae, and some Orchidaceae); perianth with dissimilar inner and outer whorls (petals and sepals), or all parts about alike (tepals), the parianth parts separate or united, commonly in 3s, less often in 2s, rarely in 5s, or perianth of scales or bristles, or entirely absent. AWorldwide, the Monocotyledonae is a group composed of ca. 55,800 species in 2,652 genera arranged in 84 families (Mabberley 1997); 25 of these families occur in nc TX. The monocots appear to be a well-supported monophyletic group derived from within the monosulcate Magnoliidae group of dicots (Chase et al. 1993; Duvall et al. 1993; Qiu et al. 1993). From the cla- distic standpoint, the dicots are therefore paraphyletic and thus inappropriate for formal recog- nition (see explantion and Fig. 41 in Apendix 6). Within the monocots, Acorus appears to be the sister group to all other monocots, with the Alismataceae (and Potamogeton) being the next most basal group (Duvall et al.

  • Vascular Plant Species of the Comanche National Grassland in United States Department Southeastern Colorado of Agriculture
    Vascular Plant Species of the Comanche National Grassland in United States Department Southeastern Colorado of Agriculture Forest Service Donald L. Hazlett Rocky Mountain Research Station General Technical Report RMRS-GTR-130 June 2004 Hazlett, Donald L. 2004. Vascular plant species of the Comanche National Grassland in southeast- ern Colorado. Gen. Tech. Rep. RMRS-GTR-130. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 36 p. Abstract This checklist has 785 species and 801 taxa (for taxa, the varieties and subspecies are included in the count) in 90 plant families. The most common plant families are the grasses (Poaceae) and the sunflower family (Asteraceae). Of this total, 513 taxa are definitely known to occur on the Comanche National Grassland. The remaining 288 taxa occur in nearby areas of southeastern Colorado and may be discovered on the Comanche National Grassland. The Author Dr. Donald L. Hazlett has worked as an ecologist, botanist, ethnobotanist, and teacher in Latin America and in Colorado. He has specialized in the flora of the eastern plains since 1985. His many years in Latin America prompted him to include Spanish common names in this report, names that are seldom reported in floristic pub- lications. He is also compiling plant folklore stories for Great Plains plants. Since Don is a native of Otero county, this project was of special interest.
