Book excerpt: The components of the vascular systems in the male floret and the female floret of Raddia are described from reconstructed serial, transverse sections. Squat tracheary elements, sieve elements, and intermediary cells comprise the systems. The male floret has six and the female floret three collateral bundles in the rachilla at the floret base that become interconnected into a lower sieve-element plexus with accompanying tracheary elements. Besides contributing to the lower plexus, the rachilla bundles serve as the traces for the lemma and palea. That bundle (bundle 3) which is the trace for the lemma median contributes most of the sieve and tracheary elements to the lower plexus. Supernumerary bundles are associated with bundle 3. Rising in the rachilla from the lower plexus is the upper plexus of sieve and tracheary elements. The circular form of the upper plexus of the male floret is influenced by the two traces from each of the anterior lodicules and by each trace from the three stamens. The trace from the posterior lodicule of the male and female florets does not influence the upper plexus. The bi-arcuate form of the upper plexus of the female floret is influenced by the two, more posterior traces from the anterior lodicules. The three staminodia in the female floret do not influence the upper plexus because they are avascular. At the pistil base is a massive amphicribral bundle, the pistil plexus, that sends down vascular prongs and lobes to merge with the upper and lower plexi. Two posterolateral (stylar) collateral bundles merge with the pistil plexus in a gynobasic manner. A placental bundle ascends from the posterior of the pistil plexus, merges with the chalaza, and exceeds the tip of the ovule before ending in a stylar core. Components of the floret vascular system of Raddia confirm the Olyreae as a tribe of the Bambusoideae that should not be placed in the subfamilies Festucoideae, Oryzoideae, or Panicoideae.

Download or read book Revision of Pearcea (Gesneriaceae) written by Lars Peter Kvist and published by . This book was released on 1996 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seventeen species of Pearcea (Gesneriaceae) are recognized, nine of which are new: Pearcea bella, P. bilabiata, P. cordata, P. fuscicalyx, P. glabrata, P. gracilis, P. grandifolia, P. intermedia, and P. strigosa. Of the remaining eight species, two were originally described in Pearcea, one is transferred herein from Kohleria, and five come from Parakohleria, a genus placed in synonymy herein. Pearcea occurs mainly on the eastern Andean slopes of Colombia (5 species), Ecuador (12 species), Peru (6 species), and Bolivia (1 species), and one species also occurs on the western Andean slopes in Ecuador. The largest number of species appears to occur in Ecuador, although additional species may occur in less explored parts of Peru. Pearcea differs from related and similar genera in the Gloxinieae by having fleshy capsules dehiscing by two valves and exposing a sticky seed mass. All species are herbs, usually with bright red flowers, and are usually found in the shady, humid forest understory, often near small streams. Hybridization, local speciation, and polymorphic variation may complicate the species delimitation. The variable Pearcea sprucei occurs throughout nearly the entire range of the genus (and includes the only accepted variety, var. parviflora), but most species are rare and local.

Download or read book Flowering Plants · Dicotyledons written by Joachim W. Kadereit and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, 24 flowering plant families comprising a total of 911 genera are treated. They represent the asterid order Lamiales except for Acanthaceae (including Avicenniaceae), which will be included in a later volume. Although most of the constituent families of the order have been recognized as being closely related long ago, the inclusion of the families Byblidaceae, Carlemanniaceae and Plocospermataceae is the result mainly of recent molecular systematic research. Keys for the identification of all genera are provided, and likely phylogenetic relationships are discussed extensively. To facilitate the recognition of relationships, families are cross-referenced where necessary. The wealth of information contained in this volume makes it an indispensable source for anybody in the fields of pure and applied plant sciences.

Download or read book A Study of the Tribe Gesnerieae, with a Revision of Gesneria (Gesneriaceae, Gesnerioideae) written by Laurence E. Skog and published by . This book was released on 1976 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study is made of the tribe Gesnerieae of the family Gesneriaceae from the West Indies, giving information on history, anatomy and morphology, pollination and dispersal, and hybridization in the tribe. The tribe comprises 67 species in 3 genera: Rhytidophyllum, Gesneria, and Pheidonocarpa. The last genus is described as new, with a new species combination, Pheidonocarpa corymbosa (Swartz) L. Skog, and 2 subspecies. A revision of Gesneria Linnaeus is presented based on field and herbarium studies. Gesneria is divided into 9 sections, 46 species (a new species, Gesneria onychocalyx L. Skog, is described), 12 subspecies, and 11 varieties. The taxonomic portion includes keys, synonymies, descriptions, typifications, distributions, and ecology, as well as distribution maps and illustrations of the taxa. Also enumerated in Appendix 1 are many species names once included in Gesnera or Gesneria, but which have been transferred to other genera. Two new combinations are made in this portion of the text: Rhytidophyllum cumanense (Hanstein) L. Skog and Rhytidophyllum onacaense (Rusby) L. Skog.

Download or read book The European Garden Flora Flowering Plants written by James Cullen and published by Cambridge University Press. This book was released on 2011-08-11 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: The European Garden Flora is the definitive manual for the accurate identification of cultivated ornamental flowering plants. Designed to meet the highest scientific standards, the vocabulary has nevertheless been kept as uncomplicated as possible so that the work is fully accessible to the informed gardener as well as to the professional botanist. This new edition has been thoroughly reorganised and revised, bringing it into line with modern taxonomic knowledge. Although European in name, the Flora covers plants cultivated in most areas of the United States and Canada as well as in non-tropical parts of Asia and Australasia. Volume 5 completes the series, and includes many important ornamental families, such as Labiatae, Solanaceae, Scrophulariaceae, Acanthaceae, Campanulaceae, and the largest family of Dicotyledons, the Compositae.

This book was released on 2016-04-19 with total page 4038 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written as a reference to be used within University, Departmental, Public, Institutional, Herbaria, and Arboreta libraries, this book provides the first starting point for better access to data on medicinal and poisonous plants. Following on the success of the author's CRC World Dictionary of Plant Names and the CRC World Dictionary of Grasses, the author provides the names of thousands of genera and species of economically important plants. It serves as an indispensable time-saving guide for all those involved with plants in medicine, food, and cultural practices as it draws on a tremendous range of primary and secondary sources. This authoritative lexicon is much more than a dictionary. It includes historical and linguistic information on botany and medicine throughout each volume.
