II. UNDIFFERENTIATED PARENCHYMA.—This has merely 
the negative character of not being transformed into either 
strengthening or secreting cells. Its abundance Is dependent 
upon the development of the strengthening cells. It will be 
seen, however, that although it furnishes no diagnostic char- 
acters, itis probably most concerned in the growth of the 
pericarp. 
Each carpel primarily contains two ovules, one of which 
soon becomes aborted (fig. 2), although it is developed sul- 
ficiently to display its nucellus and integuments, as well as 
its anatropous character. The other ovule eventually occu- 
pies the whole space of the ovarian cavity. 
The fibro-vascular connection of the ovules with the plant 
axis is as follows: A fibro-vascular bundle enters each cat- 
pel at its base, thus making it a lateral out-growth from the 
axis, while the axis itself continues its growth in the carpo- 
phore. The carpellary bundle almost at once subdivides 
into five branches, and these branches ascend the carpellary 
‘wall beneath the five primary ribs. } 
e two lateral bundles (that is, those beneath the latera 
ribs) are the largest, as they contain the fibro-vascular ele- 
ments to be distributed to the ovules. These lateral bundles 
funiculus of the anatropous ovule ( fig. 2). The remain

of the pollen-tubes, even if its nucellar structures were 
veloped to receive them.
