Se registraron 93 especies, 62 de las cuales son típicas de ambientes lénticos. La subcuenca Río Tamesí fue la que registró el mayor número de especies (68, 73.1%). No se registraron especies endémicas del estado, aunque existen 2 especies restringidas al territorio mexicano (Lobelia purpusii y Oserya coulteriana). Se consideran como raras 29 especies (31.2%) por presentarse en una sola subcuenca y sólo 2 especies están distribuidas ampliamente en la mayoría de éstas (Bacopa monnieri y Echinodorus berteroi). Un análisis de parsimonia de endemismos (PAE) de las subcuencas hidrológicas del estado con base en la presencia compartida de especies reveló que las plantas acuáticas estrictas presentan un patrón de distribución anidado. -

Pit membranes of the tracheids Received in revised form 18 February 2009 are composed of two thick layers, both constructed of fibrils much larger than those of tracheary Accepted 19 February 2009 elements of angiosperms other than Nymphaeaceae. The outer (distal) layer, which comprises the Available online 3 March 2009 continuous primary wall around the tracheids, is spongiform, perforated by porosities of relatively uniform size, and confined to or most prominent on end walls of stem tracheids. The second layer Keywords: consists of thick widely spaced fibrils that are oriented axially and are laid down proximally (facing the Microstructure cell lumen) to the first (outer) layer, although continuous with it. These axial fibrils are attached at their Nymphaeaceae Pit membrane ends to the pit cavities. This peculiar microstructure is not known outside Nymphaeaceae except in Tracheid Brasenia and Cabomba (Cabombaceae, Nymphaeales), and has not been previously described for Barclaya. Xylem The longitudinally oriented threads and strands in perforation plates of secondary xylem of wood and stems of a variety of primitive woody angiosperms (e.g., Illicium) are not homologous to the pit membrane structure observed in stem tracheids of Barclaya, which, like other Nymphaeaceae, has only primary xylem and no perforation plates. -
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.

The complex research of Nymphaea gigantea Hook plants introducing in greenhouse of water and coastal-water plants of Botanical garden named after O. V. Fomin was done. The peculiarities in structure of floating and above-water leaves of a plant were proved by anatomical researches. Key words: introduction, greenhouse, nymphaea gigantea. INTRODUCTION Among the floral biodiversity the water plants and their groups get the most anthropogenic influence and vanish because they are rather sensitive indicators of the condition of the aquatic environment. That is why most of them are included to the “Red lists” or “Red books” of the different regions of the world. The role of water plants in a biogeochemical cycle of matter and energy, in the process of self-purification of ponds is a great one and it is difficult to overestimate it. Water plants less depend on climate conditions as compared to ground-based plants that is why relic, rare genera and species among them have remained for present days. The development of Nymphaeaceae Salisb. family members goes back to Cretaceous period. One of the ways of protecting the plants of Nymphaea L genus is their introduction in the conditions of protected soil. The works on introduction and protection the members Nymphaeaceae family have been carrying out for 40 years in Botanical garden named after O. -
Factors Influencing Cross Barriers in Interspecific Hybridizations of Water Lily
J. AMER.SOC.HORT.SCI. 143(2):130–135. 2018. https://doi.org/10.21273/JASHS04302-17 Factors Influencing Cross Barriers in Interspecific Hybridizations of Water Lily Chunqing Sun1, Zhihu Ma1, Zhenchao Zhang, Guosheng Sun, and Zhongliang Dai2 Department of Vegetables, Zhenjiang Agricultural Research Institute, Jurong 212400, P.R. China ADDITIONAL INDEX WORDS. embryo abortion, Nymphaea, pollen viability, stigma–pollen incompatibility ABSTRACT. In interspecific hybridizations of water lily (Nymphaea), the existence of cross barriers makes it difficult to obtain hybrids and seriously influences the utilization of admirable characters from tropical water lilies. To determine the causes, pollen viability, pistil receptivity, and embryo and endosperm development were investigated in three water lily crosses, including Nymphaea odorata ‘Peter Slocum’ · Nymphaea micranthar (PM), ‘Peter Slocum’ · Nymphaea gigantea (PH), and ‘Peter Slocum’ · Nymphaea colorata (PC). The results indicated that the viability of pollen grains was 17.3% for ‘Peter Slocum’, 19.3% for N. colorata, 10.3% for N. micrantha, and 17.6% for N. gigantea. In the self-pollinated ‘Peter Slocum’, the number of germinated pollen grains on stigmas peaked at 12 hours after pollination (HAP), indicating its good pollen germinability. However, only a few pollen grains germinating on the sigma between 2 and 24 HAP in the crosses of PM, PH, and PC. In addition, a high percentage (81.2%) of normal embryos developed to different stages within 20 d after pollination in the self-pollinated ‘Peter Slocum’. But only 3.5% and 3.7% of normal globular embryos were observed in the PC and PM combinations, respectively. Moreover, no normal embryos were observed in the PH cross. -

Tropical regions are richer in quantity and diversity of wetlands. Aquatic plants SAMPLEare widely distributed in theseCHAPTERS areas, represented by rivers, lakes, swamps, coastal lagoons, and others. These environments also occur in non tropical regions, but aquatic plant species diversity is lower than tropical regions. Colonization of bodies of water and wetland areas by aquatic plants was only possible due to the acquisition of certain evolutionary characteristics that enable them to live and reproduce in water. Aquatic plants have several habits, known as life forms that vary from emergent, floating-leaves, submerged free, submerged fixed, amphibian and epiphyte.
