upon the stem itself ; thus, if ever ramification originates, 

 it can first occur in the floral peduncles. 



1586. As they are deficient in branches, so also are 

 they in buds agemmal or budless plants. 



1587. The tendency to produce branches forms nodes, 

 which are only imperfect ramal zones nodose plants. 



1588. Where the formation of branches is wanting, 

 the minor ramification of ribs must be also wanting in 

 the leaves ; they are parallel-ribbed. 



1589. The leaf is only a ruptured and expanded tube 

 or spathe, which surrounds the shaft spathose plants. 



1590. Where branches are wanting, there can be also 

 no petiolated leaves ; they have therefore only radical 

 leaves, from the midst of which the shaft or scape 

 sprouts forth, only as a floral-peduncle radical-leaved 

 plants. 



1591. If all these leaves be still sheathed or encased 

 within each other, they are called bulbs bulbose plants. 



1592. Since the corolla is the repetition of the leaves, 

 so also must its structure resemble theirs spathose 

 corolla. 



1593. But as there are here only radical leaves, so 

 also is the corolla only a radical leaf- corolla. In the 

 blossom, however, the radical leaf has become spathe, 

 the cauline leaf, calyx, the ramuscular leaf, corolla. 

 Such blossoms consist therefore either of a spathe only, 

 as in the Aroidese, or of a calyx calycine plants. 



1594. The stamina originate from the calyx. In 

 calycine flowers therefore all the stamina must range 

 opposite to the corolla-petals. These plants have only 

 opposite, no alternate stamina. It has been generally 

 assumed that the Monocotyledon es have no true corollse, 

 but only coloured calyces. Philosophy agrees with this 

 opinion; but adds thereunto that the corollas of the 

 Monocotyledones may be also merely spathes or invo- 

 lucra. 



1595. The separation of the bud-formation here takes 

 place for the first time in the blossom, namely, in the 

 stamina. The number of the floral parts must be limited
