The two parks are ecologically similar and geographically contiguous and are represented by a single floristic account. Also among our goals was an account of species potentially occurring in the parkland, an analyis of the flora for disjunct species, range extensions, invasive non-native species, rare taxa, and refinement of concepts of major plant communities in the parkland. A floristic inventory of the parkland records 459 naturally occurring species

  • "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.

Of the former, we might mention the splendid varieties of Cercis, with their purple flowers, the Acacias, with their airy foliage and silky stamens, the Pride of India, Colutea, and Cæsalpina, with a host of others, which, like the Sweet Pea, are redolent with perfume. Of the latter, the beans, peas, lentils, clover, and lucerne, are too well known to require recommendation. Among timber trees, the Rosewood (a Brazilian species of Mimosa), the Laburnum, whose wood is durable and of an olive-green color, and the Locust of our own country are preëminent. The following are a few important officinal products of this order. In medicine; liquorice is the product of the root of Glycyrrhiza glabra of S. Europe. The purgative senna consists of leaves of Cassia Senna, C. acutifolia, C. Æthiopica, and other species of Egypt and Arabia. C. Marilandica is also a cathartic, but more mild than the former. The sweet pulp tamarind, is the product of a large and beautiful tree (Tamarindus Indica) of the E. and W. Indies. Resins and Balsams: Gum Senegal is yielded by Acacia Verek of the River Senegal; Gum Arabic, by several species of Acacia of Central Africa; Gum Tragacynth, by Astragalus verus, &c., Persia.

This plant could form part of every region’s cultural heritage and can be transferred to the next generation. Moreover, Amaranthus is a multipurpose plant that has been identified as a traditional edible vegetable endowed with nutritional value, besides its fodder, medicinal, nutraceutical, industrial, and ornamental potentials. In recent decade Amaranthus has received increased research interest. Despite its endowment, there is a dearth of awareness of its numerous potential benefits hence, it is being underutilized. Suitable cultivation systems, innovative Citation: Ruth, O.N.; Unathi, K.; processing, and value-adding techniques to promote its utilization are scarce. However, a food-based Nomali, N.; Chinsamy, M. approach has been suggested as a sustainable measure that tackles food-related problem, especially Underutilization Versus in harsh weather. Thus, in this review, a literature search for updated progress and potential Nutritional-Nutraceutical Potential of uses of Amaranthus from online databases of peer-reviewed articles and books was conducted.

  • Literature Cited
    Literature Cited Robert W. Kiger, Editor This is a consolidated list of all works cited in volumes 19, 20, and 21, whether as selected references, in text, or in nomenclatural contexts. In citations of articles, both here and in the taxonomic treatments, and also in nomenclatural citations, the titles of serials are rendered in the forms recommended in G. D. R. Bridson and E. R. Smith (1991). When those forms are abbre- viated, as most are, cross references to the corresponding full serial titles are interpolated here alphabetically by abbreviated form. In nomenclatural citations (only), book titles are rendered in the abbreviated forms recommended in F. A. Stafleu and R. S. Cowan (1976–1988) and F. A. Stafleu and E. A. Mennega (1992+). Here, those abbreviated forms are indicated parenthetically following the full citations of the corresponding works, and cross references to the full citations are interpolated in the list alphabetically by abbreviated form. Two or more works published in the same year by the same author or group of coauthors will be distinguished uniquely and consistently throughout all volumes of Flora of North America by lower-case letters (b, c, d, ...) suffixed to the date for the second and subsequent works in the set. The suffixes are assigned in order of editorial encounter and do not reflect chronological sequence of publication. The first work by any particular author or group from any given year carries the implicit date suffix “a”; thus, the sequence of explicit suffixes begins with “b”. Works missing from any suffixed sequence here are ones cited elsewhere in the Flora that are not pertinent in these volumes.

Executive Summary This survey was a continuation of several years of rare plant survey on San Juan Public Lands. Funding for the project was provided by San Juan National Forest and the San Juan Resource Area of the Bureau of Land Management. Previous rare plant surveys on San Juan Public Lands by CNHP were conducted in conjunction with county wide surveys of La Plata, Archuleta, San Juan and San Miguel counties, with partial funding from Great Outdoors Colorado (GOCO); and in 2004, public lands only in Dolores and Montezuma counties, funded entirely by the San Juan Public Lands. Funding for 2005 was again provided by San Juan Public Lands. The primary emphases for field work in 2005 were: 1. revisit and update information on rare plant occurrences of agency sensitive species in the Colorado Natural Heritage Program (CNHP) database that were last observed prior to 2000, in order to have the most current information available for informing the revision of the Resource Management Plan for the San Juan Public Lands (BLM and San Juan National Forest); 2.
