5. Nuse, a seed covered with a hard shell which does not 



burst. Corylus, Quercus, Cannabis. 



6. Drupa, a nut covered with a thick succulent or cartilagi- 



nous coat. Prunus, Cocos, Tetragonia, Juglans, Myris- 

 tica, Sparganium. 



7. Bacca, a succulent fruit containing several seeds, and not 



dehiscing. It encloses the seeds without any determi- 

 nate order, or it is divided by a thin membrane into 

 cells. Kibes, Garcinia, Hedera, Tilia. Rubus has a 

 compound bacca. 



8. Pomum, a fleshy fruit that internally contains a capsule 



for the seed. It differs from the celled berry in having 

 a perfect capsule in the heart. Pyrus. 



9. Pepo, a succulent fruit which has its seeds attached to 



the inner surface of the rind. Cucumis, Passiflora, 

 Stratiotes. 



10. Siliqua, a dry elongated pericarp consisting of two valves 

 held together by a common permanent suture. Cruci- 

 ferse. Silicula is a small form of the same. 



11. Legumen, a dry elongated pericarp consisting of two valves 



externally forming two sutures. Leguminosse. 



12. Lomentum, a legumen divided internally by spurious 



dissepiments, not dehiscing longitudinally, but either 

 remaining always closed, as in Cathartocarpus fistula, or 

 separating into pieces at transverse contractions along 

 its length, as in Ornithopus. 

 The following are enumerated as spurious fruits : 



13. Strobilus, an amentum the scales of which have become 



woody. Pinus. 



14. Spurious capsule. Fagus, Rumex, Carex. 



15. Spurious nut. Trapa, Coix, Mirabilis. 



16. Spurious drupe. Taxus, Anacardium, Semecarpus. 



17. Spurious bacca. Juniperus, Fragaria, Basella. 



By this author the names of fruits are, perhaps, more 

 loosely and inaccurately applied than by any other.

 anatomical structure; observing, "that botanists have strayed 

 far from the right road in distinguishing these terms by 

 characters which are precise and difficult to seize. Terms are
