The morphological features, phenology, ecological notes and photographs of the species are provided. Key words: Murdannia keisak, New record, India. INTRODUCTION Commelinaceae Mirbel is representing 41 genera and about 650 species (Faden 2000) which are either widespread or mostly distributed in Africa and Asia. Murdannia Royle is one of the larger genera with 55 species worldwide (Govaerts & Faden 2014) and mainly concentrated in the tropical and subtropical regions of Asia and Africa. Karthikeyan et al. (1989) enumerated 23 species of Murdannia for India and the number is subsequently reached to 27 with some recently established new species (Ramana et al. 2013; Nandikar & Gurav 2015), of these, seven species are reported as endemic to India. The genus Murdannia in India was described by various authors in different times and some major works include Dalzell (1851), Wight (1853), Hasskarl (1870), Clarke (1871, 1874, 1881), Hooker (1894), Fyson (1920) and Rao & Kammathy (1963 & 1966).

WAYNE BARGER 1State Lands Division, Natural Heritage Section, Department of Conservation and Natural Resources, 64 North Union Street Montgomery, Alabama 36130 *Correspondence : Brian D. Holt ([email protected]) ABSTRACT The Shoal Creek Preserve Forever Wild Tract (SCPFWT) is a 123 ha property acquired by Alabama’s Forever Wild Land Program on February 26, 2003. The SCPFWT lies 13 km north-northeast of Florence, Alabama, 46 km southeast of Lawrenceburg, Tennessee, and is bordered for a short distance on the east by Shoal Creek. The site is managed by the Alabama Department of Conservation and Natural Resources for habitat conservation, outdoor recreation, and education. An intensive floristic study of this area was conducted from May 2009 through May 2011 and less frequently through June 2015. A total of 519 taxa from 346 genera and 121 families were collected, with 217 taxa representing county records. Asteraceae was the most collected family, with 69 species; Poaceae, Fabaceae, and Cyperaceae were the next largest families with 38, 29, and 17 species, respectively. Carex was the largest genus represented with 11 species. 71 non-native taxa were collected during the surveys. 42 percent of the total collections were county records and 37 exotic taxa collected during this survey were county records.

A total of 166 vascular plants (159 species, three subspecies, three varieties, and one cultivar) belonging to 132 genera and 59 families were found, accounting for 8.3% of 1,996 vascular plant species found in Seoul. Thero- phyte was the most common life-form of plants in Heonilleung Wetland. As for rare plant species, one Least Concern (LC) species was found. There were 15 floristic regional indicator species in the research area. Three of them belonged to floristic grades III and IV. This indicates that their habitats are discontinuous and isolated to some degree. Nineteen invasive alien plant species were found, most of which were introduced from North America after the year 1964 with a spread rate of V (widespread, WS).

HOAGLAND Oklahoma Natural Heritage Inventory/ Department of Geography and Environmental Sustainability University of Oklahoma Norman, Oklahoma 73019 ABSTRACT This paper documents the occurrence of a vascular plant taxon previously unknown to the flora of Oklahoma. Murdannia keisak, an Asian member of the Commelinaceae, was discovered in the Mountain Fork River in southeastern McCurtain County. KEY WORDS: Murdannia , Commelinaceae, Oklahoma, McCurtain County, exotic Murdannia keisak (Hassk.) Hand.-Mazz. (Commelinaceae; watermoving herb) is a weedy annual forb native to eastern Asia (Faden 2000; Seward 1958). In North America it was first reported in 1935 from South Carolina (Hotchkiss 1940, 1951), although the New York Botanic Garden herbarium has a Louisiana collection from 1927 (Dunn & Sharitz 1990a). It has since been found throughout the southeastern USA, as well as in Oregon and in Washington, where it is listed as a noxious weed (BONAP 2013; USDA, NRCS 2013; Washington Administrative Code 2005). Murdannia keisak has also been found in Europe (Faden 2000). The collections reported here are the first for the state of Oklahoma (Hoagland et al. 2004). Vouchers. USA. Oklahoma.

Chapter 444 the FLORA the FLORA
ChapterChapter 444 THE FLORA THE FLORA 4.1. Introduction Thousands of species of plants have been adapted to life in water or marshy areas. A significant proportion of the world’s total flora is generally growing in such habitat. The wetlands are providing the idyllic habitat for almost all kind of plants. The wetland macrophytic vegetation of the study area is quite interesting, which supports all kinds of fresh water aquatic plants. Most of the plants are herbs along with few shrubs and climbers. Few tree species also have been recorded from these regions. However, in tropical regions, different species of Eucalyptus, Acacia, Lagerostroemia, etc. are also planted in these low laying areas by different agencies. The floristic exploration of aquatic and wetland plants of different part of the world conducted by various workers including (Muenscher, 1944); (Miller & Egnler, 1950); (Fassot, 1957), (Arbar, 1963); (Lapinot, 1963); (Mason, 1969); (Godfrey & Wooten, 1979); (Minc & Albert, 1998). The endemic species number is high, which is around 13% of the total aquatic angiosperms, next to the tropical South America (Gopal, 1990). The lakes, rivers and other freshwaters bodies of Indian subcontinent support a large diversity of biota representing almost all taxonomic groups. The total numbers of aquatic plant species that exceed 1200 for aquatic and wetland systems in India (Gopal, 1990). Biswas & Calder (1937, 1955) made major survey work in India and prepared a list of aquatic angiosperms of India and Myanmar. Cook (1996) latter on revised the aquatic flora of India and reported over 485 species of aquatic and semi- aquatic angiosperms. K.

Compatibility of Translational Enhancers with Various Plant Species

Hiratsuka) Abstract Translational enhancers are effective tools to increase the expression level of transgenes in plant cells, and some candidate elements are in use today. However, knowledge about suitable elements for a given plant species are limited. We aim here to make a catalogue of translational enhancers, and evaluated the effectiveness of 5′-UTRs of Nicotiana tabacum alcohol dehysrogenase gene (NtADH 5′-UTR), Arabidopsis thaliana ADH gene (AtADH 5′-UTR), Oryza sativa ADH gene (OsADH 5′-UTR), Ω derived from tobacco mosaic virus, and tobacco etch virus leader (TEVL) in various plant species. We found that the OsADH 5′-UTR is functional in all plant species tested, and that Ω and TEVL are effective in eudicots but not in monocots. From these results, we speculate that the degree of translational enhancement of any element in a given plant species is closely correlated with the phylogenic position of the species. Key words: Alcohol dehydrogenase gene 5′-untranslated region, omega, phylogeny, tobacco etch virus leader, translational enhancer. Currently, rapid progress is being made in the field of et al.
