282 BIOLOGY. 



repeated as seed, pistil, and corolla, which together are 

 called flower, and combined, fruit, namely, nut, plum, 

 berry and apple. I designate by the term stock or 

 trunk all the parts as far as the blossom ; and this toge- 

 ther with the fruit I name thyrsus. The vegetable 

 stock, whose tissues have not yet separated into mem- 

 bers, I style, from want of a better word, thallus. As we 

 divide political kingdoms into provinces and circles, so 

 also may these titles be suitably applied here. It is 

 evident, that the plants which simply consist of tissues 

 and have as yet no sheaths and members, are the Acotyle- 

 dones ; those, however, provided with sheaths, but devoid 

 of true roots, stalk, and foliage, Monocotyledones ; those 

 with true foliage or reticular-veined leaves are, on the 

 contrary, Dicotyledones. The natural system of vegetables 

 stands accordingly in the following manner.
