Book Description
Excerpt from Comparative Wood Anatomy of Some Shrubs Native to the Northern Rocky Mountains Presented here is a key for identification of shrubby plants native to the Northern Rocky Mountain area. This key supplements those already in existence that are based on plant organs such as flowers, leaves, fruits, and other macroscopic characters. In contrast, the characters upon which this key is based are those of the wood, or technically, the xylem. Such a key would be valuable to substantiate identifications made by means of the ordinary keys and to aid in the identifications of plants when flowers, leaves, and fruits are not available. Fifty-five Species, representing 35 genera (see page have been incorporated in this key. Xylem characters determined the arrangement of the species. Where certain characters were held in common by all genera of a family, these species parallel their usual taxonomic arrangement. Depending on characters present, identification is to a species, a genus, or a group of genera. Further study will make possible more detailed identification. A review of the literature concerning wood anatomy indicates a change in emphasis has occurred Within the past 20 years-from a heavy reliance on quantitative data in distinguishing among woods to the use of qualitative characters. This change has been caused by increased understanding of the extent and causes of variations within a Species No longer is it assumed that a Single specimen accurately represents a species. To determine the range of variability of all 55 Species was beyond the scope of this study; the diversity of characters within each species will be discovered only as this key is used. In this key, cell patterns - created by the ordered activity of the cambium-are employed extensively. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
This teaching guide covers the identification, deterioration, and conservation of artifacts made from plant materials. Detailed information on plant anatomy, morphology, and development, focusing on information useful to the conservator in identifying plant fibers are described, as well as the processing, construction, and decorative techniques commonly used in such artifacts. A final chapter provides a thorough discussion of conservation, preservation, storage, and restoration methods. This is a valuable resource to conservators and students alike.
