Plants, of which above one hundred thousand different species are now known to botanists, are classified according to their relationship to one another in groups termed Natural Orders or Families, of which there are about three hundred. As the Bible plants form part only of about fifty of these families, and as they would be far apart if placed in their respective positions in the general arrangement, I deem it best to follow the original Bible classification of grass, herbs, and trees; by so doing, the allied modes of growth and products are brought together better than by either a scientific or alphabetical arrangement.
Each subject is headed by its English and Hebrew names, followed by a quotation of the verse or verses in which it occurs in the Bible, the subject under consideration being printed in italics, in some cases being followed by its Hebrew name in a parenthesis.
