 allied to the jeffersonia (Fig. 249), 

 and the pupil may be able to 

 trace resemblances in the de- 

 hiscence.

328. We know that 

 flowers are often reinforced 

 by bracts and the like. 

 (Obs. xxviii.) Fig. 275 is 

 the flower of the common 

 and handsome corn-cockle 

 (see, also. Fig. 143). The 

 corolla is convolute. The 

 calyx, with its long sepal- 

 like lobes, persists about 

 the young .pod (Fig. 276), 

 but the lobes soon fall 

 away, leaving the ripe cap- 

 sule enwrapped in the calyx -tube.

 juou weed in wheat-fields), he should determine the make-up and 



Flowers and 

 iruits of husk-tomato.
