[CH. 



Raphanus), or is jointed transversely like a Lomentum 

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



In another series of cases we find the short silicules 

 with few seeds indehiscent, sometimes devoid of the 

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

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

 practically an Achene.

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

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

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

 1 -seeded form of Aethionema.
