  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page.

  • Monocotyledons and Gymnosperms of Puerto Rico and the Virgin Islands
    SMITHSONIAN INSTITUTION Contributions from the United States National Herbarium Volume 52: 1-415 Monocotyledons and Gymnosperms of Puerto Rico and the Virgin Islands Editors Pedro Acevedo-Rodríguez and Mark T. Strong Department of Botany National Museum of Natural History Washington, DC 2005 ABSTRACT Acevedo-Rodríguez, Pedro and Mark T. Strong. Monocots and Gymnosperms of Puerto Rico and the Virgin Islands. Contributions from the United States National Herbarium, volume 52: 415 pages (including 65 figures). The present treatment constitutes an updated revision for the monocotyledon and gymnosperm flora (excluding Orchidaceae and Poaceae) for the biogeographical region of Puerto Rico (including all islets and islands) and the Virgin Islands. With this contribution, we fill the last major gap in the flora of this region, since the dicotyledons have been previously revised. This volume recognizes 33 families, 118 genera, and 349 species of Monocots (excluding the Orchidaceae and Poaceae) and three families, three genera, and six species of gymnosperms. The Poaceae with an estimated 89 genera and 265 species, will be published in a separate volume at a later date. When Ackerman’s (1995) treatment of orchids (65 genera and 145 species) and the Poaceae are added to our account of monocots, the new total rises to 35 families, 272 genera and 759 species. The differences in number from Britton’s and Wilson’s (1926) treatment is attributed to changes in families, generic and species concepts, recent introductions, naturalization of introduced species and cultivars, exclusion of cultivated plants, misdeterminations, and discoveries of new taxa or new distributional records during the last seven decades.

Friedman Premise of research. Water lilies (Nymphaeales) make up one of the oldest independent lineages of an- giosperms. The giant water lily, Victoria, exhibits pollination and floral traits that are derived within Nym- phaeales. Specialization in pollination and floral biology is often reflected in pollen traits, and in Victoria,this is evidenced by the production of permanent tetrads. Compound pollen has evolved many times across the angiosperm phylogeny, but compound pollen development has been investigated in only a few taxa, and the degree of developmental variation in microspore cohesion is unknown. This article comprehensively charac- terizes the pollen ontogenetic sequence in Victoria for the first time. Methodology. Floral buds of Victoria amazonica, Victoria cruziana, and Longwood hybrid were field collected. Anthers at the sporogenous, microspore mother cell, tetrad, “free” microspore, and mature pollen grain stages were studied using combined LM/SEM/TEM. Pivotal results. Microspore cohesion in Victoria differs from that exhibited by the few compound pollen- producing taxa that have been studied. In Victoria, the calymmate tetrads fuse via crosswall cohesion, but cytoplasmic connections are transient and do not serve as a template for wall bridge formation.

Rafikul Islam, Md. Shahrear Biozid, Md. Irfan Amin Chowdury, Muhammad Moin Uddin Mazumdar, Md. Ariful Islam and Zubair Bin Anwar Department of Pharmacy, International Islamic University Chittagong, Bangladesh Abstract: Nymphaeaceae family is well known for the flowering water plants which are traditionally used in various neurological diseases. So, the purposes of the examination was to evaluate sedative action of the methanol extract of Nymphaea capensis leaves using animal models along with its cytotoxicity assay on brine shrimp. Adult male Swiss albino mice were treated with extract at 200 and 400 mg/kg doses and then subjected to behavioral tests such as open field, hole cross, elevated plus-maze (EPM) and thiopental Na-induced sleeping time test to assess sedative activities. In-vitro cytotoxicity assay was performed on shrimps of Artemia salina. In hole cross and open field test locomotors activity and exploratory behavior were reduced in the test group compared with the control groups. Percentage time spent in open arm in EPM test was increased for test groups in a dose dependent manner. Reduced onset of sleeping time and increased duration of sleeping time also indicated CNS depressant effect of the extract which was comparable with the standard drug diazepam. The extract shows LC50 value 271.584 µg/ml in the brine shrimp cytotoxic test.

  • Pollen Ontogeny in Brasenia (Cabombaceae, Nymphaeales)1
    American Journal of Botany 93(3), 344–356 2006. POLLEN ONTOGENY IN BRASENIA (CABOMBACEAE,NYMPHAEALES)1 MACKENZIE L. TAYLOR2,3 AND JEFFREY M. OSBORN2,4 2 Division of Science, Truman State University, Kirksville, Missouri 63501-4221 USA Brasenia is a monotypic genus sporadically distributed throughout the Americas, Asia, Australia, and Africa. It is one of eight genera that comprise the two families of Nymphaeales, or water lilies: Cabombaceae (Brasenia, Cabomba) and Nymphaeaceae (Victoria, Euryale, Nymphaea, Ondinea, Barclaya, Nuphar). Evidence from a range of studies indicates that Nymphaeales are among the most primitive angiosperms. Despite their phylogenetic utility, pollen developmental characters are not well known in Brasenia. This paper is the first to describe the complete pollen developmental sequence in Brasenia schreberi. Anthers at the microspore mother cell, tetrad, free microspore, and mature pollen grain stages were studied using combined scanning electron, transmission electron, and light microscopy. Both tetragonal and decussate tetrads have been identified in Brasenia, indicating successive microsporogenesis. The exine is tectate-columellate. The tetrad stage proceeds rapidly, and the infratectal columellae are the first exine elements to form. Development of the tectum and the foot layer is initiated later during the tetrad stage, with the tectum forming discontinuously. The endexine lamellae form during the free microspore stage, and their development varies in the apertural and non-apertural regions of the pollen wall. Degradation of the secretory tapetum also occurs during the free microspore stage. Unlike other water lilies, Brasenia is wind-pollinated, and several pollen characters appear to be correlated with this pollination syndrome. The adaptive significance of these characters, in contrast to those of the fly-pollinated genus Cabomba, has been considered.

  • Water Lilies As Emerging Models for Darwin's Abominable Mystery
    OPEN Citation: Horticulture Research (2017) 4, 17051; doi:10.1038/hortres.2017.51 www.nature.com/hortres REVIEW ARTICLE Water lilies as emerging models for Darwin’s abominable mystery Fei Chen1, Xing Liu1, Cuiwei Yu2, Yuchu Chen2, Haibao Tang1 and Liangsheng Zhang1 Water lilies are not only highly favored aquatic ornamental plants with cultural and economic importance but they also occupy a critical evolutionary space that is crucial for understanding the origin and early evolutionary trajectory of flowering plants. The birth and rapid radiation of flowering plants has interested many scientists and was considered ‘an abominable mystery’ by Charles Darwin. In searching for the angiosperm evolutionary origin and its underlying mechanisms, the genome of Amborella has shed some light on the molecular features of one of the basal angiosperm lineages; however, little is known regarding the genetics and genomics of another basal angiosperm lineage, namely, the water lily. In this study, we reviewed current molecular research and note that water lily research has entered the genomic era. We propose that the genome of the water lily is critical for studying the contentious relationship of basal angiosperms and Darwin’s ‘abominable mystery’. Four pantropical water lilies, especially the recently sequenced Nymphaea colorata, have characteristics such as small size, rapid growth rate and numerous seeds and can act as the best model for understanding the origin of angiosperms. The water lily genome is also valuable for revealing the genetics of ornamental traits and will largely accelerate the molecular breeding of water lilies.
