276 PLANTS. 
seed-bearing, or female organs of Linnzeus, usually occu- 
pying the centre of the flower, and single ; the fecundating, 
or male organs of Linneeus, generally more numerous, 
mostly five, surrounding the females in a circle: neither of 
these organs serving for more than a single fecundation and 
production of seeds, but withering and falling off, although - 
new organs of the same kind are frequently produced on 
the same plant in the following years. ‘The fecundation 
effected by the motion of the atmosphere, or the passage 
of insects, either carrying the fecundating liquid from the. 
one organ to the other, or occasioning the approach of the 
two organs, and the moisture of the one then causing the 
rupture of the other, and the consequent emission of the 
fecundating fluid. The seeds sometimes growing until they 
become similar to their parent before they fall off and are 
dispersed. 
Pants are primarily divided into three series. 
1, PLANTA CELLULOSE. 
Structure cellular; embryo 0, reproduced by spore. 
2. PLANTA ENDOGENZ. 
Structure vascular; trunk cylindrical, homogeneous, the 
centre youngest; embryo undivided ; cotyledon 1; plumule 
extra-axile. 
3. PLANTA EXOGENZE. 
Structure vascular; trunk conical, composed of wood 
covered with bark, the outer part of the wood youngest; 
embryo divided ; cotyledons 2 or many; plumule axile. 
Series I. PLANTA CELLULOSAK. 
PLANTS composed entirely of cellular texture, having 
neither lymphatic, spiral, nor proper vessels, nor any cor- 
tical pores. Corculum simple; cotyledons 0; propagation 
mostly gemmaceous. iy 
Divided into two subseries: A, aphylleze; B, foliaceze.
