✦ Synopsis
This handy little book written by a teacher with considerable experience is unique in more than one way. It is unique in the method of presentation, unique in the large numher of excellent photographs used t o illustrate a single point and unique in that it leaves nothing uncsplained to a beginner in Hotany. The latter point is especially valuable because too many authors of scientific textbooks for beginners seem t o take it for granted that the student already knows considerable about the subject.
The introduction has some excellent gencralities and the properties of protoplasm are described in a very clear way. Here also the plant cell is shown to differ from the animal cell in six ways.
Nearly half the book deals with the lower forms of plants and into these 96 pages is crowdcd a wealth of valuable information about thcse lowly forms which too few people know about.
In part I "spccial attention is given t o the development and relationship of plants, to the modification of the reproductive process and organs, and t o the developmcnt of new tissue or special modifications of old tissue in each succeeding higher group." In this part a single species is taken t o represent each group of plants and by fully describing this species a n excellent idea of the life processes and morphology of the entire group is obtained. Each plant is described under well-arranged headings, for instance, the discussion of the White Pine, representing the Gymnosperms, is arranged under the following paragraphs: Habitat, Morphology of the Sporophyte, Reproduction, Distribution of Pollen, Pollination, Development of the Male Garnetophyte, Development of the Sperms, Fertilization, Seed Formation, and Seed Germination."
"In part I1 attention is given to descriptive Botany. This part contains all the facts necessary for a complete understanding of the study of roots, stems, buds, leaves, flowers, fruits and seeds." Each of these organs is described in a separate chapter and the different types, shapes, etc., are all illustrated by many photographs which are well reproduced.
