Plant Biology Textbook by Graham, Wilcox & Prentice Hall [Hardcover 2002] - Essential Botany Resource for College Students & Plant Science Enthusiasts

OK, so I may be a little biased, but I took Linda Graham's general botany class last year, in which this book is followed to the letter. Although I didn't read the book thoroughly, Professor Graham's lectures covered everything in it. I enjoyed learning the material in this book, as is covers a wide spectrum of things about plants. Although the last couple of chapters (dealing with conservation of resources, etc.) were a bit tedious at times (since it's all stuff that has been pounded into our heads for years), the rest of the book is excellent. A nice blend of pictures, examples, and explanations.
