264 PHYLLODY 



real in the cases now to be mentioned. In Slnapis and 

 in Brassica oleracea foliaceous ovules may occasionally 

 be seen, attached to the placenta by long stalks. No 

 trace of the nucleus is visible in these specimens. 



Pio. 140. Sinaipia, repltun and ovules ; the dotted line shows the 

 position of the carpels. 



Griffith, in alluding to a similar case in Sinapis,^ 

 describes the ovules as foliaceous, and having their 

 backs turned away from the axis, the raphe being next 

 to the axis and representing the midrib the funicle 

 corresponding to the petiole. The outer tegument 

 of the ovule, according to Griffith, is a leaf united 

 along its margins, but always more or less open at 

 its apex. No inversion can, therefore, really take place 

 in anatropous ovules, but the blade of the leaf is bent 

 back on the funicle, with which its margins also cohere. 



Caspary, in an elaborate paper on phyllomorphy 

 occurring in Trifolium repens, figures foUaceous ovules 

 springing from the edge of an open, leafy carpel. The 

 nucleus of the ovule, in these cases, appears to origi- 

 nate as a little bud from the surface of the leafy 

 o^^lle (figs. 141, 142).
