4. " Epicorollcs Synantherce ; the essential distinction between this 

 and the preceding section consists in the anthers of this cohering- by 

 their edges, forming a tube round the style; and from the succeeding, by 

 the corolla being inserted on the top of the ovary, not on the bottom or 

 tube of the calyx. 



5. " To this section the vast order Compositoe alone belongs ; as 

 examples of which it may suffice to mention the humble Daisy, the 

 common Thistle, the Artichoke, the Dandelion, and gaudy Dalia, to 

 enable every one to understand what is meant by a compound flower, 

 the general flower of each of these being made up of a congeries of 

 small ones. 



6. " PericorolJae ; in this, as in the two preceding sections, the 

 petals are united into a monopetalous corolla, but in place of being in- 

 serted on the top of the ovary, it is inserted on the tube, or towards the 

 base of the calyx; leaving the ovary either partially or altogether 

 free. 



The Lobelia, the Hairbell, and Heath tribes, afford examples of 

 this last section of the 2d class. 



III. " CoEOLLiFLOR.E. — This sub-class differs from the thrc^ last 

 sections of the preceding, in the insertion of the corolla only : like them 

 the corolla is monopetalous, bearing the stamens; but, in place of being 

 inserted on the calyx (perigynous), springs from the receptacle or base 

 of the flower, inferior to the ovary (hypogynous) : hence, in the language 

 of Jussieu, the section is now named Hypocorollae (see table below). 



The Jasmines and Convolvulus afford the most familiar examples 

 of this class, but the Gentians, Trumpet flowers (Bignonia), Helio- 

 tropes, Verbenas, Solanums (Brinjal, Potatoe, &c.) all belong to it. 



IV. " jVIoNocnLAMYDEiE. — This sub-class is characterized by having 

 a single perianth, that is, only one verticel or whorl of floral envelopes, 

 or if two are at any time present, the petals adhere to the calyx. It is 

 divided into four sections. 



1. ** Hypostarnineae ; here the stamens are inserted on the receptacle, 

 and the ovary is free, even though concealed within the tube of the 

 calyx, to which it does not adhere. The Marvel of Peru ( Mirahilis 

 J a lap a J, so mnch prized as a garden ornament, and the Amaranthus, 

 appertain to this section. The flower of the former, often so delicately 

 variegated, is in truth only a petaloid expansion of the calyx, and not a 

 corolla, in the glabose inflated bottom of which, the filaments and ovary 

 are found perfectly fre*?. This lower portion of the calyx afterwards 

 forms the black shell-like covering of the seed.
