blest Mosses or the minutest Moulds, spring from single cells or 

 spores (97), and not from true seeds. And the apparatus by which 

 these spores are produced, whatever be its nature, is not a flower. 

 Plants of the lower grade (98, 

 99) are therefore collectively 

 denominated 



113. Flowerless or Cryptoga- 



fflOUS Plants. The first name 

 expresses the fact that the or 

 gans of fructification in these 

 plants are not of the nature 

 of real flowers. The second 

 name, which was introduced 

 by Linnajus, and is composed 

 of two Greek Avords meiming 

 " concealed fructification," re- 

 fers to the obscure nature of 

 the organs' or the processes of 

 reproduction in these plants, 

 which have only recently come 

 to be understood. Some ac- 

 count of them will be given 

 in Chapter XII.

114. Flowering or Phaenogamous Plants,* — so called in contradis- 

 tinction to the Flowerless or Crypt ogamous, — is the general name 

 for the higher grade of plants, to which our ordinary herbs, slu'ubs, 

 and trees belong, and which may be said to exhibit the perfected type 

 of vegetation. The lower grade begins with plants so simple as to 



* Sometimes ■\\Titten Phanero(jamous. Both terms are made from the same 

 Greek words, and signify, by a metaphorical expression, the counterpart of 

 Cryptogamous ; that is, that the essential organs of the flower are manifest or 

 conspicuous.
