offered by the inert side necessarily compels the extensible one 

 to turn round the centre of resistance, and the ovule curves 

 upon itself. 



In the other instance, since the hilum retains its place, the 

 vascular bundle which brings it into communication with the 

 chalaza is forced to follow the ovule in its evolution, and forms 

 by its elongation, a cord more or less prominent within the 

 thickness of the primine which is called the raphe, (pa^ a 

 line.) 



Some botanists think that the anatropous ovule, is simply 

 an orthotropous ovule inverted on an elongated funiculus or 

 podosperm, (nov; a foot, and <jrtp/*a a seed,) which is attached 

 in the form of a raphe to one side of the ovule. But the 

 raphe r, Fig. 62, appears to be an elongation of the vascular 

 bundles which connect the chalaza with the hilum ; and this 

 view is established by the fact that in anatropous ovules, the
