 missing petal marked by a dotted line. 



Fig. 242. Flower of a Monkshood. 243. Its p.arts disjilayed ; five sepals, the up-

 The two pieces under the hood represent the corolla, reduced to two odd-shaped 

 petals; in centre the numerous stamens and three pistils. 244. Diagram of the 

 calyx and corolla; the three dotted Hues in the place of missing petals.
