PHYTOLOGY. 313 



which fleshy matter has accumulated, and whose internal 

 tunic or endocarp has become woody. The berry is a 

 many-seeded hollow capsule, which, as well as the calyx, 

 has become soft and succulent. 



1722. The apple is an ovarium surrounded by a fleshy 

 calyx. 



CLASS XIII. 



Nut-plants Apetala, Diclines. 



1723. Ovarium woody, and inclosing only one seed. 

 Here belong the Apetalous and Diclinous Exogens. 



1724. These plants repeat the fungi, grasses and Syn- 

 genesia, and have therefore imperfect corollae, the calyx 

 of which has alone remained, and usually closely sur- 

 rounds the nut. 



1725. The stalk is indeed usually woody; yet is 

 still found to be also herbaceous and nodose with spathi- 

 form leaves. The leaves are simple, frequently needle- 

 shaped or else arrested. The principal ingredients are 

 starch, as in the Gramineaa and Syngenesia. 



1726. The inflorescence is mostly amentaceous, as in 

 the Agarics, Grasses and Syngenesia. 



1727. They divide into androgynous and dioecious 

 plants. 



1728. First order, Nucaria parenchymatosce. Her- 

 maphrodite herbs with nodes and spathose leaves, calyx 

 green, superior, and quinquepartite with five opposite 

 stamina ; nut mostly triangular and utricular. 



1729. Second order, N. vaginata. Form of vegetation 

 pretty nearly as in preceding order, but the calyx is corolla- 

 like, and the stamina mostly alternate Phytolaccete, 

 lUecelrece. 



1730. Third order, N. axonales. Hermaphrodite, 

 calyx corolla-like, superior and wholly quaternary ; herbs 

 and shrubs bearing nuts and plums Nyctaginea, Dctph- 

 nece, and Santalacece. 



1731. Fourth order, N. for ales. Trees, calyx corolla- 

 like but inferior; capsules, plums and berries Pro- 

 tcaccce.
