Preliminary Phytochemical investigations revealed the presence of Steroids, Tannins, Alkaloids, Carbohydrates, Flavonoids, Glycosides and Saponins. Successive extraction was carried out to obtain petroleum ether, chloroform, alcohol and water extract .Literature review of ipomoea species shown to possess allelopathic activity. So an attempt was made systematically to notice growth suppression by ipomoea hederifolia and ipomoea indica on Methi, Fennel, Paddy ,Ground nut and Mungbean plants by in Vitro sandwich method developed by Dr Fujii . HPTLC study of both the species ensured the presence of scopoletin in significant amount. Keywords - Ipomoea Hederifolia, Ipomoea Indica, Allelopathic Activity, HPTLC, Scopoletin I. INTRODUCTION negative allelopathic effects are an important part of plant defense against herb ivory (i.e., animals Allelopathy. Allelopathy refers to the beneficial eating plants as their primary food). or destructive effects of one plant on another plant, both harvest and weed species, from the 1.1 Application of allelopathy: release of biochemical’s, known as The possible application of allelopathy in agriculture allelochemicals, from plant parts by leaching, is the subject of much research. Current research is root exudation, volatilization, residue rotting, and focused on the effects of weeds on crops, crops on other processes in both natural and agricultural weeds, and crops on crops. systems. Allelochemicals are a subset of secondary metabolites not required for This research furthers the possibility of using metabolism (growth and development) of the allelochemicals as growth regulators and allelopathic organism.

    Appendix Color Plates of Solanales Species The first half of the color plates (Plates 1–8) shows a selection of phytochemically prominent solanaceous species, the second half (Plates 9–16) a selection of convol- vulaceous counterparts. The scientific name of the species in bold (for authorities see text and tables) may be followed (in brackets) by a frequently used though invalid synonym and/or a common name if existent. The next information refers to the habitus, origin/natural distribution, and – if applicable – cultivation. If more than one photograph is shown for a certain species there will be explanations for each of them. Finally, section numbers of the phytochemical Chapters 3–8 are given, where the respective species are discussed. The individually combined occurrence of sec- ondary metabolites from different structural classes characterizes every species. However, it has to be remembered that a small number of citations does not neces- sarily indicate a poorer secondary metabolism in a respective species compared with others; this may just be due to less studies being carried out.

Weaver, Jr., Ph.D., and Patti J. Anderson, Ph.D. For this period, 167 specimens were submitted to the Botany Section for identification, and 1,418 were received from other sections for identification/name verification for a total of 1,585. In addition, 57 specimens were added to the herbarium, and 48 specimens of invasive species were prepared for the Division of Forestry’s Forest Health Project. Some of the samples received for identification are discussed below: Helianthus simulans E. E. Wats. (an endemic North American genus of 49 species, occurring throughout the United States and adjacent Canada, as well as in Baja California). Compositae (Asteraceae). Muck sunflower. It is unfortunate that such an attractive plant has such an unattractive common name. Growing to more than 2 m tall, this sunflower makes a showy and impressive specimen in the garden. In its best forms, the lanceolate leaves are leathery and dark green, somewhat reminiscent of those of the oleander (Nerium oleander). The flower heads, with bright yellow rays and usually a reddish- purple disk, are borne in profusion in October and November and vary from 7-10 cm across. Although it grows at least twice as tall and the leaves are broader and not revolute (turned under along the margins), it is often confused with the very common Helianthus simulans Photograph courtesy of Sally Wasowski and swamp sunflower (H.

Markedly furrowed xylem characterizes the genera of tribe Cresseae. Successive cambia occur in 11 of the genera studied. Large patches of axial parenchyma occur in many of these; only in one species was interxylary phloem (formed internally by the cambium) observed in the parenchyma patches. Intraxylary phloem at the periphery of the pith is universal in Convolvulaceae, but newly reported is the fact that in many species, cambial activity adds secondary phloem to the intraxylary phloem strands. These cambia were also observed to add limited amounts of secondary xylem externally in Ericybe and Operculina.

Felix Street, Bldg. 23 Fort Worth, Texas 76115-3404 ABSTRACT The U.S. Army Corps of Engineers (Corps) administers the National Wetland Plant List (NWPL) for the United States (U.S.) and its territories. Responsibility for the NWPL was transferred to the Corps from the U.S. Fish and Wildlife Service (FWS) in 2006. From 2006 to 2012 the Corps led an interagency effort to update the list in conjunction with the U.S. Environmental Protection Agency (EPA), the FWS, and the USDA Natural Resources Conservation Service (NRCS), culminating in the publication of the 2012 NWPL. In 2013 and 2014 geographic ranges and nomenclature were updated. This paper presents the fourth update of the list under Corps administration. During the current update, the indicator status of 1689 species was reviewed. A total of 306 ratings of 186 species were changed during the update.

Fresh plant materials (stem, petiole, and leaf) were fixed immediately in Formalin-Acetic- Alcohol for 24h, dehydrated, embedded in paraffin wax sectioned using rotary microtome, Sections were stained with Safranin and counterstained with Alcian blue and micro-photographed with trinocular research microscope fitted with Amscope digital camera. Ipomoea coccinea is twisting climber with reddish flowers; vine is up to 10 m long with alternate leaf arrangement. The leaf is amphistomatic and dorsiventral. The epidermal cells are irregular in shape with wavy anticlinal walls.
