FRUIT. 



[section U. 



376. The Pyxis is a pod which opens by a circular horizontal line, the 

 upper part forming a lid, as in Purslane (Fig. iOi), the Plantain, Hen- 

 bane, etc. In these the dehiscence extends all round, or is cir- 

 cumseissile. So it does in Amaranth (Fig. 387), forming a one- 

 seeded utricular pyxis. In Jeffersonia, the line does not separate 

 quite round, but leaves a portion for a binge to the lid. 

 377. Of Multiple or Collective Fruits, which are properly 

 masses of fruits aggregated 

 into one body (as is seen in 

 the Mulberry (Fig. 408), Pine- 

 apple, etc.), there are two kinds 

 with special names and of pe- 

 culiar structure. 

 378. The Syconium or Fig- 

 403 402 404 fruit (Fig. 405, 406) is a fleshy 



axis or summit of stem, hollowed out, and lined within by a multitude of 

 nunute flowers, the whole becoming pulpy, and in the common flg, luscious.
