10 ELEMENTS OF BOTANY. [SECTION 1. 



5 The vegetable kingdom is so vast and various, and the difference is 

 so wide between ordinary trees, shrubs, and herbs on the one hand, and 

 mosses, moulds, and such like on the other, that it is hardly possible to 

 frame an intelligible account of plants as a whole without contradictions 

 or misstatements, or endless and troublesome qualifications. If we say 

 that plants come from seeds, bear towers, and have roots, stems, and 

 leaves, this is not true of the lower orders. It is best for the beginner, 

 therefore, to treat of the higher orders of plants by themselves, without 

 particular reference to tlie lower. 



6. Let it be understood, accordingly, that there is a liigher and a lower 

 series of plants ; namely : — 



Phaneeogamous Plants, which come from seed and bear flowers, es- 

 sentially stamens and pistils, through the co-operation of which seed is 

 produced. Por shortness, these are commonly caRed Phanero&ams, or 

 Phtsnogams, or by the equivalent English name of Ploweking Plants.* 



CaYPiOGAMOUS Plants, or Ckyptogams, come from minute bodies, which 

 answer to seeds, but are of much simpler structure, and such plants have 

 not stamens and pistils. Therefore they are called in English Ploweuless 

 Plants. Such are Perns, Mosses, Algse or Seaweeds, Pungi, etc. These 

 sorts have each to be studied separately, for eacii class or order has a plan 

 of its own. 



7. But Phanerogamous, or Plowering, Plants are all constructed on one 

 plan, or fi/pe. That is, taking almost any ordinary herb, shrub, or tree for 

 a pattern, it will exemplify the whole series : the parts of one plant answer 

 to the parts of any other, with only certain differences in particulars. And 

 the occupation and the delight of the scientific botanist is in tracing out 

 this common plan, in detecting the likenesses under all the diversities, and 

 in noting the meaning of Ihese manifold diversities. So the attentive study 

 of any one plant, from its growth out of the seed to the flowering and 

 fruiting state and the production of seed like to that from which the plant 

 grew, would not only give a correct general idea of the structure, growth, 

 and characteristics of Plowering' Plants in general, but also serve as a pat- 

 tern or standard of comparison. Some plants will serve this purpose of a 

 pattern much better than others. A proper pattern will be one that is 

 perfect in the sense of having all the principal parts of a phanei'ogamous 

 plant, and simple and regular in having these parts free from complications 

 or disguises. The common Flax-plant may very well serve this purpose. 

 Being an annual, it has the advantage of being easily raised and carried 

 in a short time through its circle of existence, from seedling to fruit and 

 seed. 



1 The name is sometimes Phanerogamous, sometimes Phienogamoiis (Fkanero- 

 (jams, or Phcenogams), terms of the same meaning etymologically ; the former of 

 preferable form, but the latter shorter. The meaning of such terms is eipjaiued 

 in the Glossary.
