tains germinal powder, is an internal spathe, which corre- 

 sponds to the germinal leaf of grasses. 



1352. The oral teeth are the dissevered parallel strips 

 of vessels in the culm and leaf of the Monocotyledons. 



1353. The urn-supporting pedicel is the seed -petiole 

 or umbilical cord. 



1354. The calyptra probably corresponds to the arillus 

 and thus to the bud-scales ; or possibly to the indusium 

 of the ferns, and thus to the ovary. 



1355. The leaf-roses would consequently be the invo- 

 lucral leaves of the moss-stalk ; the moss-stalk itself a 

 peduncle or flower-stalk ; so that in the upper involucral 

 leaves rudiments might indeed appear of stamina. 



1356. In the lichens and fuci the whole trunk is none 

 other than seed-shell. 



1357. In the fungi, the antetype of the Acotyledons, it 

 may be almost said that the whole stem is nothing else but 

 albumen, the external layers of which only cling together 

 in a membranaceous manner, and represent a kind of 

 seed-shell. The fungus is an albumen-body, which has 

 coagulated out of vegetable juices. In the fungus, seed, 

 seed-vessel, ovary, blossom, foliage and trunk have be- 

 come blended into one. 



1358. In a perfect blossom the albumen is therefore 

 the repetition of a fungus ; the acotyledonous seed that 

 of lichen ; the monocotyledonous seed-vessel that of a 

 moss ; the dicotyledonous, however, is the repeated fern. 

 It may be also said that the albumen were fungus ; the 

 germ, lichen ; the seed-vessel, moss ; the ovary perhaps, 

 a fern, namely, its indusium.

1359. The life of the plant consists in the co-operation 

 of its functions. The representation of these functions 

 is the vegetable physiology or the theory of vegetation. 



1360. Vegetation depends frst of all upon the two 

 principal antagonisms of the plant, or those between the 



tr ache at and cellular systems, or between the stem- and root-
