    Notes: [Auszug] Cronshaw3 examined these thickenings in the electron microscope, and was able to show that the 'awns' which appear to project into the cell lumen, were in fact attached along their length to the radial walls, the thickenings usually tapering off in thickness towards the tangential wall. Carbon ...

    Notes: [Auszug] Sections cut after maceration with hdryogen peroxide acetic acid showed that this treatment removed the lining membrane, but the enclosed outgrowth of the cell wall forming the vesture was attacked at apparently the same rate as the cell wall itself. The lining membrane (Figs. 1 and 2) was strongly ...

    Notes: [Auszug] We have found no reports in the literature of driftwood travelling over such long distances (10,000 miles). Cockayne4 mentions in passing that logs are carried from New Zealand to the Chatham Islands, a distance of 500 miles. Matthews5 states that the fjords of the west coast of South Georgia ...

    Description / Table of Contents: Zusammenfassung Die Infrarot-Spektren (4000...250 cm-1) dünner Holzchnitte (12μm) von einigen gefäßführenden Gymnosperment der Ordnung Gnetales, sowie von einem gefäßlosen Angiospermen der Familie Winteraceae zeigten mit Spektren von typischen Angiospermen — und nicht etwa mit denjenigen von Gymnospermen — eine große Ähnlichkeit. Diese Ergebnisse deuten darauf hin, daß die chemische Zusammensetzung einer bestimmten Holzart nicht durch deren anatomisches Gefüge bedingt ist; sie zeigen fernerhin, daß die Ordnung Gnetales chemisch den Angiospermen nahesteht.
    Notes: Summary Infrared spectra (4000...250 cm-1) of thin sections (12μm) of woods from some pored gymnosperms of the order Gnetales and of a non-pored angiosperm of the family Winteraceae have been obtained and found to resemble closely the spectra of typical angiosperms rather than gymnosperms. These results indicate that the gross chemical composition of a wood is not related to its anatomical structure and show that chemically the Gnetales resemble angiosperms.
