90 Mr. Lindley's Account of the Spherical and 



former is called Nutrition, the latter Generation. Hence there 

 is a twofold system of organs ; namely, of nutrition and of 

 multiplication. But the organs of nutrition are either pre- 

 pared by the mother (Germi?iatiori) 9 or developed by the plant 

 itself {Vegetation); so also the organs of multiplication are 

 either confined to the plant {Flowering) or continued in a new 

 individual {Fructification). 



There are therefore four primary functions of vegetables : ger- 

 mination, vegetation, flowering, and fructification. This is the 

 basis of my system. 



§ 20. According to these two systems of organs, and four 

 primary functions of life, the following arrangement is pro- 

 duced of Vegetables. 



B. Organs of Multiplication. 



c. in Flowering. 



1. Phsenogamous, having 

 sexes or manifest flowers. 



2. Cryptogamous, having 

 no sexes, and destitute of 

 flowers. 



d. in Fructification. 



1. Spermideous, bearing 

 seeds. 



2. Sporideous, bearing 

 sporides. 



Organs of Nutrition. 



produ- 



in Germination. 



1. Cotyledoneous, 

 cing cotyledons. 



2. Nemeous, producing a 

 thread. 



b. in Vegetation. 



1. Vascular, having cellidar 

 tissue and spiral vessels. 



2. Cellular, having cellidar 

 tissue,and no spiral vessels. 



§ 21. Upon the same principles Cotyledoneous Vegeta- 

 bles (Vascular, Phanerogamous, and Spermideous) are di- 

 vided according to 



B. Organs of Multiplication, 

 c. in Flowering. 



1. (Androdynamous?) 



2. (Gynodynamous?) 



A. Their Organs of Nutrition. 



a. in Germination. 



1. Dicotyledoneous, with a 

 double expanded cotyle- 

 don. 



2. Monocotyledoneous, with 



a single inclosed cotyledon. 



b. in Vegetation. 



1. Exogeneous, the trunk 

 youngest at the circum- 

 ference. 



2. Endogeneous, the trunk 

 youngest, and softest in 

 the centre. 



* Agardh defines a Semen, or Seed, to be 

 " A separate fully-formed embryo, divided into cotyledons, and with or 

 without albumen." 



A Graiunn, or Grain, he defines as " An undivided leafless embryo, ad- 



nate 



d. in Fructification. 

 1. Seminiferous*.

2. Graniferous.
