"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.

Mishler, Chair Professor David D. Ackerly Professor Katherine N. Suding Spring 2013 Abstract Adaptive Traits and Community Assembly of Epiphyllous Bryophytes By Ekaphan Kraichak Doctor of Philosophy in Integrative Biology University of California, Berkeley Professor Brent D. Mishler, Chair Leaf surfaces of tropical vascular plants provide homes for diverse groups of organisms, including epiphyllous (leaf-colonizing) bryophytes. Each leaf harbors a temporally and spatially discrete community of organisms, providing an excellent system for answering some of the most fundamental questions in ecology and evolution. In this dissertation, I investigated two main aspects of epiphyllous bryophyte biology: 1) adaptive traits of bryophytes to living on the leaf surface, and 2) community assembly of epiphyllous bryophytes in space (between-hosts) and time (succession). For the first part, I used published trait data and phylogeny of liverworts in family Lejeuneaceae to demonstrate that only the production of asexual propagules appeared to evolve in response to living on the leaf surface, while other hypothesized traits did not have correlated evolution with epiphylly. The second portion dealt with the assembly of communities among different host types.

Cadamba: a Miraculous Tree Having Enormous Pharmacological Implications
PHCOG REV. REVIEW ARTICLE Cadamba: A miraculous tree having enormous pharmacological implications Alka Dwevedi, Kuldeep Sharma1, Yogesh K Sharma2 Sri Aurobindo College, University of Delhi, South Campus, 1Department of Botany, University of Delhi, North Campus, 2Department of Chemistry, Swami Shraddhanand College, University of Delhi, North Campus, New Delhi, India Submitted: 22-07-2014 Revised: 15-09-2014 Published: 04-08-2015 ABSTRACT The Cadamba is one of the important medicinal plants belonging to the Rubiaceae family. It is crucially significant as it has the largest number of phytochemicals and secondary metabolites (viz., cadambagenic acid, cadamine, quinovic acid, β-sitosterol, cadambine, etc.) having pharmacological and biological properties. It can be used as an alternative to various synthetic chemical compounds in the prevention as well as the treatment of several incurable diseases. More than 100 years of research has been done to discover various phytochemicals and their implications. Very few of them, i.e. ≤2% have been commercialized due to the lack of a suitable model system as well as various associated controversial issues. The solubility of phytochemicals is another major concern: Further response that will be generated due to the solvent used is also unpredictable. Moreover, the Cadamba is one of the ornamental plants with religious significance. Here we have made an effort to summarize all the phytochemicals and their significance to render the interest that would help in their commercialization. Key words: Anticancer, antioxidant, Cadamba, pharmacology, phytochemical INTRODUCTION of plants is used for medicinal treatments; either whole or in specific part/s (bark, root, leaves, fruit, flowers, seeds), in There is a number of flora in use for medicinal purposes over the dried state.

Department of Pharmacognosy and Drug Development, Faculty of Pharmaceutical Sciences Ahmadu Bello University, Zaria, - Nigeria. *Corresponding author (+2348032845569; [email protected] ) ABSTRACT The present study investigates the phytochemicals and thin layer chromatographic profile of Nauclea diderrichii (Rubiaceae) leaf extracts. Phytochemical in the hexane, ethyl acetate and methanol extracts were determined using standard chemical tests. Thin layer chromatographic techniques were carried out using various solvent systems of varying polarity on these extracts. Preliminary phytochemical screening revealed the presence of alkaloids, glycosides, saponins, phenolic compounds, tannins, phytosterols, carbohydrates, flavonoids and terpenoids. Further screening using thin layer chromatographic technique on the N. diderrichii leaf extracts also revealed different phytochemical compounds with different R f values. The results obtained in present study indicated that Nauclea diderrichii leaf is a rich source of phytochemicals. This could justifies the use of plant species in traditional medicine for treatment of various diseases. Keywords: Nauclea diderrichii, Rubiaceae Leaf extracts, Phytochemicals, Retention factor, TLC. INTRODUCTION Due to the reputation of N. diderrichii in folk Medicinal plants are of great importance to the health medicine, especially the leaf being use to cure of individuals and communities in general. The numerous ailments, this study was carried out to medicinal value of such medicinal plants lies in the identify the bioactive compounds responsible for these chemical substances present in the plants that activities.

High Frequency Regeneration of Plants Via Callus-Mediated Organogenesis
www.nature.com/scientificreports OPEN High frequency regeneration of plants via callus-mediated organogenesis from cotyledon and hypocotyl cultures in a multipurpose tropical tree (Neolamarkia Cadamba) Hao Huang1, Ying Wei1, Yongjin Zhai1, Kunxi Ouyang2, Xiaoyang Chen2* & Longhua Bai1* In this works, a simple, efcient and repeatable protocol was developed for in vitro regeneration via callus-mediated organogenesis of Neolamarkia Cadamba using cotyledonary petioles and hypocotyls. Efects of basal medium, plant growth regulators, the types and age of explant on the formation of adventitious buds/shoots were studied. Meanwhile, histological analysis for early ontogenic stages and genetic stability assessment by fow cytometry were investigated. Our investigation demonstrated that, compared with 6-benzyladenine (BA), N6-(2-isopentenyl) adenine (2-ip), Thidiazuron (TDZ) was the optimal cytokinin for buds/shoots induction on cotyledon and hypocotyl explants. Douglas-fr and sugar pine medium (DCR) supplemented with 22.7 μM TDZ and 0.27 μM α-naphthalene acetic acid (NAA) was most efective on bud induction, with the highest bud-induction rate and numbers of buds on cotyledon and hypocotyl explants. The available shoot per explant hit 35.2 when the induced callus sub-cultured to a medium without TDZ. It was found that TDZ could promote induction of the callus and the buds, however, continuous exposure beyond 4 weeks of supplemented high concentration (exceed 11.35 μM), TDZ was harmful to the proliferation and growth of buds/shoots. DCR appeared more efciency than Murashige and Skoog medium (MS), Woody Plant medium (WPM), anther culture of cereal crops medium (N6) on bud induction. Age of cotyledon and hypocotyl explants in 20-day to 25- day was most benefcial to adventitious buds/shoots formation.
