Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The American Botanist, 1902, Vol. 3: Devoted to Economic and Ecological Botany The roots of epiphytal Orchids differ from those of terrestrial plants is being covered with a white papery substance, called the velamen, and the cells of the velamen serve the double purpose of condensing or absorbing aqueous vapour from the atmosphere, when any is present, and of protecting the underlying cells from excessive evaporation during periods of drought. In its absorp tive character it is analagous with the outer cells of the bog-mosses (sphagnum) and L'eucobrjmm, where the small chlorophyll-bear ing cells are covered by large colourless cells, having very thin walls, which are variously perforated, and not only absorb water in liquid state, like a sponge, but also have the power of condens ing it when in the form of vapour. A double function appertains to the roots of epiphytal Orchids, firstly to fix the plant to the bark and secondly to supply it with nutriment. When the tip of a root comes in contact with a solid body it adheres closely to it, flattens itself out more or less, develops papilliform or tubular cells, which grow into organic union with the substratum, and act as holdfasts. But if the root extends beyond the limit of the substratum it ceases to develop these clamp - cells, and hangs down in the form of a white filament. Many o-f these aerial roots do not become attach ed at all but hang freely in the air, often forming regular tassels.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The American Botanist, Vol. 2: Devoted to Economic and Ecological Botany; January, 1902 All plants grown in arid places tend to develop very thick, succulent stems, having little or no leaves, but a very thick skin to prevent the absorption of their life juices by evaporation. A very good instance of this is to be found in the common ice plant which grows so thickly along our beaches, just above high-water mark.

This book was released on 2000-01-01 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: A systematic survey and comparison of the work of 19th-century American and British women in scientific research, this book covers the two countries in which women of the period were most active in scientific work and examines all the fields in which they were engaged. The field-by-field examination brings out patterns and concentrations in women's research (in both countries) and allows a systematic comparison of the two national groups. Through this comparison, new insights are provided into how the national patterns developed and what they meant, in terms of both the process of women's entry into research and the contributions they made there. Ladies in the Laboratory? features a specialized bibliography of nineteenth century research journal publications by women, created from the London Royal Society's Catalogue of Scientific Papers, 1800-1900. In addition, 23 illustrations present in condensed form information about American and British women's scientific publications throughout the nineteenth century. This well-organized blend of individual life stories and quantitative information presents a great deal of new data and field-by-field analysis; its broad and methodical coverage will make it a basic work for everyone interested in the story of women's participation in nineteenth century science.
