TITLES OF THE CLASSES. 



this class six stamina, four of which are longer than the rest 5 

 which circumstance distinguishes them from those of the sixth 

 class, where the six stamina are equal : but these flowers have 

 their particular character also, their corollas being cruciform*. 



Class 16. Monadelphia.— The word here, compounded with 

 the numerical term, signifies a brother. This relation is employ- 

 ed to express the union of the filaments of the stamina, which in 

 this class do not stand separate, but join at the base, and form 

 one substance, out of which they proceed as from a common 

 mother; and the title of the class expresses a single brotherhood, 

 meaning that there is but one set of stamina so united, which di- 

 stinguishes the class from the two following ones. The number 

 of stamina in this class is not limited : the flowers have their 

 particular character-}-. 



Class 17. Diadelfhia. — This term expresses a double bro- 

 therhood, or two sets of stamina, united in the manner explained 

 in the preceding class. The number of the stamina is not limited : 

 the flowers of this class have a very particular character, their 

 corolla being papilionaceous, as will be shown in its placet. 



Class 1 8. Polyadelphia. — This term expresses many brother- 

 hoods, or sets of stamina ; the flowers have no classic character 

 farther than is expressed in the title. 



Class 19. Syngenesia. — -This* class contains the compound 

 flowers described in Part I. Chap. 19. The title signifies congene- 

 ration, alluding to the circumstance of the stamina; in which, 

 though the filaments stand separate, yet the anthera?, subservi- 

 ent to generation, are united in a cylinder, and perform their 

 office together. The classic character will be explained in its 

 place,!.
