Of the eighteenth Class, Poeyadelphia. 
This class consists of such plants as bear hermaphrodite flowers, 
furnished with many sets of united stamina: the flowers have no 
particular character farther than is expressed in the title. The orders 
are four, viz. 
Order I. PENTANDRIA, comprehending such plants as have 
five stamina in each set. Of this order there are two genera, viz. 
Theobroma, Chocolate Nut, and Abroma. 
Oedeh II. DODECANDRIA, comprehending such plants as 
Lave twelve stamina in each set. Of this order there is but one 
genus, viz. Monsonia. 
Order III. ICOSANDRIA, comprehending such plants as have 
twenty stamina in each set. Of this order there is but one genus, 
viz. Citus, Citron. 
Order IV. POLYANDRIA, comprehending such plants as 
have many stamina in each set. This order contains eight genera, 
viz Hypericum, St. John’s Wort, Ascyrum, St. Peter’s Wort, Hopea, 
Symplocos, Melaleuca, Durio, Munchhausia, and Glabrana. 
Of the nineteenth Class , Syngenesia. 
This class consists of such plants as bear compound flowers. We 
have already paved the way for understanding this class, by the ex- 
planation of the titles of the class and its orders. What is farther 
necessary here, is to give the characters of the flowers. Compound 
flowers admit of a double description, viz. of the whole flower m its 
aggregate state, which is termed the Flosculose and Flower : 2. of 
the Flosculi florets, of which it is composed. We shall begin with 
the first, which concerns only the calyx and receptacle, those being 
the only parts that are in common.
