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
A page-turning novel that is also an exploration of the great philosophical concepts of Western thought, Jostein Gaarder's Sophie's World has fired the imagination of readers all over the world, with more than twenty million copies in print. One day fourteen-year-old Sophie Amundsen comes home from school to find in her mailbox two notes, with one question on each: "Who are you?" and "Where does the world come from?" From that irresistible beginning, Sophie becomes obsessed with questions that take her far beyond what she knows of her Norwegian village. Through those letters, she enrolls in a kind of correspondence course, covering Socrates to Sartre, with a mysterious philosopher, while receiving letters addressed to another girl. Who is Hilde? And why does her mail keep turning up? To unravel this riddle, Sophie must use the philosophy she is learning—but the truth turns out to be far more complicated than she could have imagined.
