INTRODUCTION. 1X 
1. Peripetale with several distinct petals inserted on the calyx towards its base, leaving the 
ovary superior or free—Leguminose, the section Poteniillee of Rosacec, and Salicariee all afford 
easily understood examples of this section. 
2. Epipetale,—n this section the tube of the calyx is prolonged and lined by the torus 
which forms a small disk on the summit of the ovary, and the ovary is enclosed by and coheres with 
calyx tube: the distinct petals and stamens are inserted on the outside of the disk. The ovary is 
here said to be inferior or adherent and the flower superior. Rosee, Pomee and Combretacee, 
apparently afford examples of this section, but want the disk on the summit of the ovary. 
Umbellifere, Araliacee and Cornee are the only orders referred here as being truly epipetalous. 
3. Kpicoralle Corisanthere ; this section differs from the last in having the petals united, 
forming a monopetalous corolla, bearing the stamens inserted on ite tube, and the anthers not 
cohering round the style. The common honey-suckle is a familiar example of this section to 
which also the elder, thecoffee, valerian &c., that is the orders Caprifoliacee, Rubiaceae, Valeri- 
ane@ &c. belong. 
4. Epicorolle Synanthere: 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 Composite alone belongs; as examples of which it may 
suffice to mention the humble Daisy, the common Thistle, the Artichoke, the Dandilion, 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. Pericorollae: in this, as in the two preceding sections, the petals are united into a mono- 
petalous Corolla, but in place of being inserted 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 all together free. 
The Lobelia, the Hairbell, and Heath tribes afford examples of this last section of the 2d 
class. 
Tif. Corrottirtora#.—This sub-class differs from the three 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 Hypocoroliae (see table below). 
The Jasmines and Convolvulus afford the most familiar examples of this class but the 
relat Trumpet flowers (Bignonia) Heliotropes,Verbenas, Solanums (Brinjal, Potatoe,&c.) all 
eiong to It. 
Sti EV: MonocutAmype.®.—This sub-class is characterized by having a single perianth, that 
is, only one verticel or whor! of floral envelopes, or if two are any time present, the petals adhere 
to the calyx. It is divided into four sections. es, 
2. Peristamineae. In this the stamens are inserted on the calyx, not hypogynous. 
Chenopoglium, Polygonum and the beautiful Begonia are examples of this section. se,
