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. At the same time, no seeds were obtained in PM, PC, and PH crosses. The results suggest that prefertilization barriers existed in the PH cross, whereas pre- and postfertilization barriers existed together in the PC and PM crosses. These may be the main causes resulting in the failure of interspecific hybridizations in water lily.

Various associations have long existed in China, of which secrecy was at an early period the prominent feature, since the jealousy of the imperial government declares the association of even five persons to be illegal, and punishes the crime of belonging to these associations with death. Among these fraternities may be enumerated—1st, the Great Ascending Society; 2nd, the Society of Glory and Splendour; 3rd, the Union of the Three Great Towers, viz., Heaven, Earth, and Man; 4th, the White Jackets; 5th, the Red Beards; 6th, the Short Swords; 7th, the White Water-Lily; 8th, the Sea and Land Society; 9th, the Righteous Rising Society, &c. The third of these associations, which, from all that can be gathered, assimilate in their origin, is the one that prevails in Canton, and obtains almost exclusively in the Straits of Malacca, and the vast islands of the Indian Archipelago; and which will principally form the subject of this notice. It is commonly known under the terms of Tien-ti-huih, or San-ho-huih, and is sometimes divided into two branches—the Canton and Fokien, to which provinces most of the Chinese emigrants belong. Those from Canton, are, I believe, by far the most numerous. Other societies or Kongsis exist, with the benevolent object of raising funds for the assistance and support of those among their number in distress; but they are almost all subject, more or less, to some of the objections that exist against the Tien-ti-huih.

Investigations were conducted on calamus, common cattail, soft rush, yellow iris and white water lily plants in twenty ponds in Malopolska and Podkarpacie Regions. Mycobiota existing in the phyllosphere caused discolouring and necroses of leaves and shoots. 88 species of mycobiota were identified and isolated from the diseased tissues. Dominant were <em>Alternaria alternata, Epicoccum nigrum</em> and <em>Isaria farinosa</em>. Fungi of genera: <em>Aspergillus, Botrytis, Chaetomium, Cladosporium, Fusarium, Ilyonectria, Mortierella, Mucor, Penicillium, Phialophora, Phoma, Pleustomophora, Sordaria, Trichoderma</em> and <em>Umbelopsis</em> were also numerous. The monophagous and the polyphagous were identified.

Cellulose nanofibrils (CNF) were prepared by cellulase in conjunction with mechanical disintegration from the bleached softwood kraft pulp and labelled by Congo red dye. The labelled CNF were used to investigate the retention and distribution of CNF in paper handsheets. The retention of the labelled CNF was obtained by measuring the absorbance of white water using an ultraviolet-visible spectrophotometer. The results showed that this method for measuring the retention was rapid, feasible, and sensitive, owing to the high correlation coefficient R2 (0.9993) of the standard curve. The labelled CNF showed even distribution in paper handsheets. The colorimetric values of paper handsheets were explored with a residual ink analyzer.
