Paspalum is a rather large genus “numbering nearly 400” species (Chase, 1929). Sour paspalum (Paspalum conjugatum) stands by itself in this genus as suggested by Chase (1929) who created for it, alone, the Section Conjugata (Fig. 1). Its most unusual character is the vigorously stoloniferous habit allowing, at times, for a rapidly formed perennial ground cover. Sour paspalum has been assumed to be native where it occurs in the Americas, from Florida to Texas and southward to Peru, Bolivia, and northern Argentina, from sea level to 4,000 ft elevation. The grass was first described from a specimen collected in Surinam (Dutch Guiana). Sour paspalum has been assumed, however, to be intro- duced wherever it occurs in the Old World tropics (Fig. 2) and Pacific Islands. The early trade routes were between Australia, Singapore, and Africa. Probably both carpetgrass (Axonopus compressus) and sour paspalum, being of similar distribution and ecology, were spread at the same time to the same places.

    Fauna and Flora Baseline Study for the De Wittekrans Project Mpumalanga, South Africa Prepared for GCS (Pty) Ltd. By Resource Management Services (REMS) P.O. Box 2228, Highlands North, 2037, South Africa [email protected] www.remans.co.za December 2008 I REMS December 2008 Fauna and Flora Assessment De Wittekrans Executive Summary Mashala Resources (Pty) Ltd is planning to develop a coal mine south of the town of Hendrina in the Mpumalanga province on a series of farms collectively known as the De Wittekrans project. In compliance with current legislation, they have embarked on the process to acquire environmental authorisation from the relevant authorities for their proposed mining activities. GCS (Pty) Ltd. commissioned Resource Management Services (REMS) to conduct a Faunal and Floral Assessment of the area to identify the potential direct and indirect impacts of future mining, to recommend management measures to minimise or prevent these impacts on these ecosystems and to highlight potential areas of conservation importance. This is the wet season survey which was done in the November 2008. The study area is located within the highveld grasslands of the Msukaligwa Local Municipality in the Gert Sibande District Municipality in Mpumalanga Province on the farms Tweefontein 203 IS (RE of Portion 1); De Wittekrans 218 IS (RE of Portion 1 and Portion 2, Portions 7, 11, 10 and 5); Groblershoek 191 IS; Groblershoop 192 IS; and Israel 207 IS. Within this region, precipitation occurs mainly in the summer months of October to March with the peak of the rainy season occurring from November to January.

  • Non-Native Invasive Plants of the City of Alexandria, Virginia
    March 1, 2019 Non-Native Invasive Plants of the City of Alexandria, Virginia Non-native invasive plants have increasingly become a major threat to natural areas, parks, forests, and wetlands by displacing native species and wildlife and significantly degrading habitats. Today, they are considered the greatest threat to natural areas and global biodiversity, second only to habitat loss resulting from development and urbanization (Vitousek et al. 1996, Pimentel et al. 2005). The Virginia Department of Conservation and Recreation has identified 90 non-native invasive plants that threaten natural areas and lands in Virginia (Heffernan et al. 2014) and Swearingen et al. (2010) include 80 plants from a list of nearly 280 non-native invasive plant species documented within the mid- Atlantic region. Largely overlapping with these and other regional lists are 116 species that were documented in the City of Alexandria, Virginia during vegetation surveys and natural resource assessments by the City of Alexandria Dept. of Recreation, Parks, and Cultural Activities (RPCA), Natural Lands Management Section. This list is not regulatory but serves as an educational reference informing those with concerns about non-native invasive plants in the City of Alexandria and vicinity, including taking action to prevent the further spread of these species by not planting them. Exotic species are those that are not native to a particular place or habitat as a result of human intervention. A non-native invasive plant is here defined as one that exhibits some degree of invasiveness, whether dominant and widespread in a particular habitat or landscape or much less common but long-lived and extremely persistent in places where it occurs.

  • The Naturalised Flora of South Australia 3. Its Origin, Introduction, Distribution, Growth Forms and Significance P.M
    J. Adelaide Bot Gard. 10(1): 99-111 (1987) THE NATURALISED FLORA OF SOUTH AUSTRALIA 3. ITS ORIGIN, INTRODUCTION, DISTRIBUTION, GROWTH FORMS AND SIGNIFICANCE P.M. Kloot South Australian Department of Agriculture, GPO Box 1671, Adelaide, South Australia 5001 Abstract Some features of the South Australian naturalised flora were examined. The predominant source of naturalised alien species has changed from Europe or Eurasia in 1855 to the Mediterranean and environmentally similar areas at present. It is suggested that this is due to the history of northern European settlement of South Australia and the attendant importation of plants from that region. The majority of presently naturalised plants were recorded in Great Britain at the time of South Australian settlement and it is suggested that regardless of their ultimate origin, most plants would have arrived via Great Britain or, more generally, northern Europe. The majority of naturalised plants have been documented or are suspected to have been introduced intentionally. Most of them were ornamental, fodder or culinary plants. Of the unintentionally introduced species, most were fleece, seed or ballast contaminants. A number of characteristic distribution patterns of naturalised plants in South Australia are recognized. These result from climatic and edaphic features and from patterns of land use. Annuals are the predominant growth form of the well-established species. The majority of the unintentionally introduced species are annuals. Introduction The development of the South Australian alien flora since colonization (Kloot, 1987) was ascertained from the documentation discovered during an intensive search (Kloot, 1987) to locate more material than was thought available hitherto (Michael, 1972).

  • Investigation of Mitochondrial-Derived Plastome Sequences in the Paspalum Lineage (Panicoideae; Poaceae) Sean V
    Burke et al. BMC Plant Biology (2018) 18:152 https://doi.org/10.1186/s12870-018-1379-1 RESEARCH ARTICLE Open Access Investigation of mitochondrial-derived plastome sequences in the Paspalum lineage (Panicoideae; Poaceae) Sean V. Burke1* , Mark C. Ungerer2 and Melvin R. Duvall1 Abstract Background: The grass family (Poaceae), ca. 12,075 species, is a focal point of many recent studies that aim to use complete plastomes to reveal and strengthen relationships within the family. The use of Next Generation Sequencing technology has revealed intricate details in many Poaceae plastomes; specifically the trnI - trnL intergenic spacer region. This study investigates this region and the putative mitochondrial inserts within it in complete plastomes of Paspalum and other Poaceae. Results: Nine newly sequenced plastomes, seven of which contain an insert within the trnI - trnL intergenic spacer, were combined into plastome phylogenomic and divergence date analyses with 52 other species. A robust Paspalum topology was recovered, originating at 10.6 Ma, with the insert arising at 8.7 Ma. The alignment of the insert across Paspalum reveals 21 subregions with pairwise homology in 19. In an analysis of emergent self- organizing maps of tetranucleotide frequencies, the Paspalum insert grouped with mitochondrial DNA. Conclusions: A hypothetical ancestral insert, 17,685 bp in size, was found in the trnI - trnL intergenic spacer for the Paspalum lineage. A different insert, 2808 bp, was found in the same region for Paraneurachne muelleri. Seven different intrastrand deletion events were found within the Paspalum lineage, suggesting selective pressures to remove large portions of noncoding DNA. Finally, a tetranucleotide frequency analysis was used to determine that the origin of the insert in the Paspalum lineage is mitochondrial DNA.
