"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. -

This is hardly surprising given the importance of the sector to the economy, and the role of mathematical modelling in the valuation of instruments and the assessment of risk. What is striking is that, with some notable exceptions, few mathematicians have been actively engaged in the design of financial markets. This is undoubtedly a serious challenge with parallels from other large-scale complex networks: to design a distributed system, linking self-interested and intelligent agents, so that the outcome is effective and efficient. How would an ideal market operate, to allow liquidity between long-term investors to be provided by short- term traders? In the second part of the talk I outline some preliminary work, joint with Elena Yudovina, on this question. I describe a simplified and analytically tractable model of a limit order book where the dynamics are driven by stochastic fluctuations between supply and demand. The model has a natural interpretation for a highly traded market on short time scales where there is a separation between the time scale of trading, represented in the model, and a longer time scale on which fundamentals change. There has been considerable discussion recently of the effects of competition between multiple high- frequency traders, and of proposals aimed to slow down markets. -

Although Partridge Berry Is a Small and Creeping Herb, Its Jewel-Like Beauty Rewards Attentive Naturalists Year-Round
Virginia Native Plant Society 2012 Wildflower of the Year Partridge Berry Mitchella Repens Although partridge berry is a small and creeping herb, its jewel-like beauty rewards attentive naturalists year-round. Description Partridge berry is a low-growing, herbaceous perennial that forms mat-like colonies of interlaced stems on the forest floor. Near their growing tips, stems are smooth or, when young, sparsely hairy; in older sections of a colony, stems bear adventitious roots. Branch stems arise either singly or in pairs, frequently from nodes below the previous year’s fruit, but sometimes from other nodes as well. The 1-2-cm- long leaves are opposite, evergreen, round to ovate, and somewhat leathery; the upper leaf surface is glossy, with a whitish mid- vein. Successive pairs of leaves are off-set 90° from the pair above and below, but this decussate arrangement is often obscured in older, fully prostrate, stems. Small, sharp- pointed stipules extend between petiole bases on each side of the nodes. Typically, flowers form in pairs at the ends of slightly upturned stem tips. The paired flowers have a common pedicel and exhibit various degrees of fusion with each other, especially in their lower regions. There are four scale-like sepals at the base of each flower, but these commonly fuse together, forming a common calyx for the pair of flowers. Four white petals form a gradually expanding corolla tube that ranges from 9 to 14 mm in length and is topped by spreading lobes that are 3-4 mm long and densely hairy on their inner surfaces. -

Campylotropy in the Circumscription of the Morindeae Descriptions in Early
BLUMEA 35 (1991) 307-345 The genera Mitchellaand Damnacanthus. Evidence for their close alliance; comments on the campylotropy in the Rubiaceae and the circumscription of the Morindeae E. RobbrechtC. Puff & A. Igersheim Summary The two species of Mitchella (Southeast Asian and North American) and several species of the character Southeast Asian genus Damnacanthus are investigated. Vegetative states (growth form, described and branching pattern, leaves) of the two genera are compared. Damnacanthusalways ex- hibits heterophylly and some species have paired thorns. The latter are interpreted as paired lateral of branch and it is that the thorns shoots in the proximal part a sympodial unit, speculated paired be modified inflorescence shoots. may Detailed information is also given on inflorescence structure and floral morphological and ana- tomical details of Damnacanthus and Mitchella. Particular emphasis is placed on the ovaries, the structure of which is remarkably similar in the two genera. The uniovulate locules are characterized ovules which inserted the of extensive by having campylotropous are near top the septum; obturator tissue covers part of the horizontally arranged curved ovule in cap-like manner.The micropyle of the ovule, obscured by the obturator,points upwards and to some degree also inwards, while the embryo sac is found in a ± horizontal position. The seeds, however, contain minute embryos, of which the radicles are pointing ± downwards. This apparently contradicting micropyle and radicle position finds its in the unusual ovule and orientation and in the explanation structure subsequent strong growth of the endosperm, through which the embryo is pushed to the position where it is found in mature seeds. -
