RECAPITULATION. 101 



ticillate. The termination of the peduncle upon which 

 the flower sits has several names, receptacle, torus, etc. 

 When it supports but one flower, it is proper ; when a 

 cluster, it is common. 



The germ is the base of the style, and the stigma its 

 apex ; the rudimentary seeds, the ovules. When the germ 

 is fully developed it becomes fruit. This consists of peri- 

 carp and seed. The pericarp may be a shell, pod, or pulp. 



Fruits are divided into dehiscent and indehiscent. In- 

 dehiscent are those which do not open when matured, and 

 are subdivided into drupe, berry, pepo, and pome. Dehis- 

 cent are those which do open when matured, and are sub- 

 divided into legume, follicle, silicle, silique, capsule, and 

 pyxis. 



Seeds are sometimes furnished with appendages, as down, 

 aigret, wings, and scales. A seed consists of three parts, 

 embryo, albumen, epidermis. The embryo contains the 

 cotyledon,- plumula, and radicle. 



We commenced at the root, and — like the mariner, who, 

 sailing west, if he sails Idng enough and far enough, will 

 reach the port he left — we have, by continually traveling 

 upward, found ourselves where we started from, at the bot- 

 tom of the plant again, the radicle or root. 



Section XL— General Remarks. 



You have been told that plants consist of solids and 

 fluids, that these constitute various tissues, cellular, vas- 

 cular, woody, and lactiferous. These are made from inor- 

 ganic substances held in solution by the water drawn from 

 the soil by the spongioles, by gases taken from the earth 

 by the roots, and from the air by the leaves. That by the 

 process of assimilation they are converted into material 

 identical with the plant, and that this material is deposited 

 by the sap in its descending flow.
