Capsule not very large, opening in three valves, and 

 expelling about six black seeds : 



Fig. 147. Box, Buxus sempervirens. 1, flowering shoot ; 2, a male, 

 and 3, a female flower ; 4, vertical section of latter ; 5, ripe fruit opening ; 

 6, carpellary walls; 7, seed. All but 1 enlarged (Wo). 



Buxus sempervirens, L. Box (Fig. 147). The outer 

 part of the pericarp separates from the endocarp and 

 splits longitudinally down through the three styles and 

 dorsal sutures, thus producing three two-horned valves. 

 The endocarp in turn opens down six lines so suddenly as 

 to fling forth the contained seeds. The capsule is an 

 explosive one.
