down to the seed, whereby the germ first becomes 

 developed or self-subsistent. 



2. PISTIL OR OVARY. 



1276. If the corolla be the light-flower, the stalk-flower 

 is heat-flower. 



1277. The stalk-flower, as being a repetition of the 

 stem, must be developed later than the leaf-flower. It 

 consequently stands superiorly upon, and so far within, 

 this. The corolla is related to the stalk-flower like cir- 

 cumference to centre. 



1278. The stalk repeated in the flower is the Ovarium, 

 germen or pistillum. It is frequently converted into 

 wood in the nut and becomes hardened into stone. 



1279. Nevertheless, the pistil like the corolla is a 

 leaf-formation, because everything that originates sub- 

 sequently to, can be none other than, the leaf. It is a 

 leaf-bud under the idea of the stalk. The pistil is thus a 

 leaf-whorl like the corolla, and one which is subject to 

 the same fatalities, only with this difference, that its leaves 

 are wont to open first after it has withered, and conse- 

 quently through physical forces. 



1280. Every leaf that has been closed in a vesicular or 

 tubular form is a follicle or carpel. There are therefore 

 uni-, bi-, and tri-locular ovaria, &c. The loculi or cells of 

 the ovarium are none other than closed carpels. As 

 many therefore as there are of the former, so many are 

 there of the latter, and vice versa. The septa or parti- 

 tion-walls are none other than the involuted edges of the 

 closed and confluent carpels. 



1281. Uni-locular ovaria consist therefore only of one 

 leaf. The legume is only a compressed carpel. 



1282. Every carpel or every cell has its raphe or 

 suture directed inwards or along the axis of the flower. 

 Eor the leaves are always so conjoined that the two halves 

 of the upper or inner side stand counter to each other. 



1283. All other sutures are adventitious and, by their 

 mode of dehiscence, determine those parts of the ovarium 

 which are called valves. These sutures are either dorsal
