As a result of the examination of fractured tracheids ofPinus insignisit is shown that an outer lamella (presumed to be the primary layer) of the tracheid wall is composed of cellulose chains which lie at an angle of some 11° to the transverse plane

Irene Manton was by profession a cytologist but she was much else besides: a violinist, a collector of modern and Chinese painting, and knowledgeable about Chinese printing. She was a versatile classical botanist, but her real interests lay in two sp

A brief review is given of the changing views over the years, as knowledge of wall structure has developed, concerning the mechanism whereby cellulose chains may be oriented. This leads to an examination of current concepts, particularly those concer

Filaments of the red alga Griffithsia flosculosa have been examined by the methods of X-ray analysis, polarization optics, and electron microscopy, including ultra-thin sectioning. The main structural component of the wall consists of cellulose II (m

This is the first of two papers dealing with the wall structure and growth of Chaetomorpha (Ch. melagonium and Ch. princeps ) and of Cladophora (Cl. prolifera and Cl. rupestris ). Here the structure is investigated of the side walls and cross-walls o

The extensibility of cell walls in segments of living Avena coleoptiles has been determined after treatment with IAA by the use of a microextensometer. It has been demonstrated that IAA has an effect both on the plastic and elastic extensi bility, wh

The structure of the walls of vesicles of Valonia ventricosa and, to a less extent of other species, has been re-examined by the methods of X-ray analysis and electronmicroscopy, with particular reference to the criticism by Steward & Muhlethaler of

The wall structures of Cladophora, Chaetomorpha and Spongomorpha have been examined by X-ray diffraction analysis and by electron microscopy, and earlier results have been confirmed and extended. The walls of the two former species contain microfibri
