[CH. 



Raphanus), or is jointed transversely like a Lomentum 

 (Raphanus, Fig. 56) and breaks across at the segments. 



In another series of cases we find the short silicnles 

 with few seeds indehiscent, sometimes devoid of the 

 partition. When, as iu Myagrum, Crambe (Fig. 57), &c, 

 this occurs and the seed is reduced to one, ths fruit is 

 practically an Achene.

Winged siliques, silicules (Lepidium, Fig. 58, Mega- 

 carpcea), and achenes (Peltaria) are also common, and in 

 the last case are to all appearances Samaras, as in the 

 1 -seeded form of Aethionema.
