CRUCIFERyE AND CAPPARIDACE/E 



53 



Iii some genera (e.g. Cremolobus, Fig. 60) the two 

 lalves of the silicule come away from the axis enclosing 

 ach its single seed, like mericarps from the carpophore 

 o a Cremocarp, only in comparing with the fruit of 

 imbellifers we must remember it is here superior. 



Some crucifers bear two kinds of fruit on the same 

 ilant e.g. achene and silicule in Aethionema, lomentum 

 md silique in Chorispora, and even siliques aDd silicules 

 n Cardamine, the latter ripening underground. Subter- 

 anean silicules also occur in Geococcus and Morisia.

In the Capparidacese the simplest typical fruit is like 

 i silique, but without the longitudinal partition, so that 

 vhen the valves of the capsule separate they leave the 

 ieeds on the margins of the replum, but the latter has no 

 nembrane across e.g. Gleome (Fig. 61) but here again 

 >ach valve may come away like a mericarp, bringing the 

 ingle seed (the rest being aborted) with it e.g. Wisli- 

 -,enia. In Dipterygium (Fig. 62) the fruit is indehiscent, 

 las only one seed, and is winged, like a samaroid achene. 



Next we get a series where the pericarp becomes 

 leshy and the fruit is therefore Baccate. In Capparis
