each its proper Pedicellus*, or partial foot-sialk, raised to. 

 3 proportionable height, as in Spirjea OpuLiFOLiA,...and Le- 

 dum. 



6*. A Panicle, is a fructification dispersed on peduncles va- 

 riously subdivided. It is a Diffuse panicle, when the pedicelli 

 are divaricate, spreading asunder; and a Cqarctate or confined/ 

 one, when they stand close to each other. 



7. A Thrysu&, is a panicle contracted into an ovate form, as 

 in Syringa and Petasites. 



8. A RACEMUsf consists of a peduncle that has short lateral 

 branches, as in Vrris...and Ribes.

 are subsessilej, and are produced in rings round the stems. 



V. A Petiole, or footstalk of a leaf, is a species of trunk that 

 fastens the leaves, but not the fructification ; which circumstance 

 distinguishes it from a peduncle, which is the foot-stalk of a 

 flower, as has been explained above. There are some cases 

 where the fructification and leaves are born on the same foot- 

 stalks, as in TuRNERA...and Hibiscus; but these instances are 

 very rare. 



VI. Frons §, is a species of trunk, composed of a branch and 

 leaf blended together; and is frequently united with the fruc- 

 tification: it belongs properly to the Palms.., and FiLiCEsj|. 



* In the Philosophic! Botanica, it is not PediceUus, but Petiolus ; which seems 

 to be a mistake, this term being applied to leaves only. It-may be translated 

 Peduncle. Editor.

^ With no foot-stalks, or with very short ones. Editor.
