INDEX I. 



DESCRIPTIVE NOMENCLATURE. 



PLANTS in perfect form are said, at page 22, to consist of 

 four principal parts : root, stem, leaf, and flower. (Compare 

 Chapter V., 2.) The reader may have been surprised at the 

 omission of the fruit from this list. But a plant which has 

 borne fruit is no longer of ' perfect ' form. Its flower is dead. 

 And, observe, it is further said, at page 49, (and compare 

 Chapter HI., 2,) that the use of the fruit is to produce the 

 flower : not of the flower to produce the fruit. Therefore, 

 the plant in perfect blossom, is itself perfect. Nevertheless, 

 the formation of the fruit, practically, is included in the 

 flower, and so spoken of in the fifteenth line of the same 

 page. 



Each of these four main parts of a plant consist normally 

 of a certain series of minor parts, to which it is well to attach 

 easily remembered names. In this section of my index I will 

 not admit the confusion of idea involved by alphabetical ar- 

 rangement of these names, but will sacrifice facility of refer- 

 ence to clearness of explanation, and taking the four great 

 parts of the plant in succession, I will give the list of the 

 minor and constituent parts, with their names as determined 

 in Proserpina, and reference to the pages where the reasons 

 for such determination are given, endeavouring to supply, at 

 the same time, any deficiencies which I find in the body of 

 the text.
