Sambucus ; for Jussieu's Hortensia is, according to 

 all appearance, a Hydrangea, and, however near to 

 these two genera in habit, very different in structure. 

 This Section is characterized by 3 sessile Stigmas, 

 though the Seed is solitary in Viburnum. 



The 4th Section is formed of Cornu^zad Hedera, 

 which have a polypetalous Corolla, and no external 

 Calyx, except what is common to numerous Flowers. 

 They are slightly akin. Hedera naturally belongs to 

 the Aralia:, Ord. 59. Jussieu himself candidly ex- 

 presses his dissatisfaction with the Order in question. 



Class 12. Dicotyledones. Corolla polypeta- 

 lous. Stamens epigynous. 



" Calyx of one leaf, superior. Petals of a definite num- 

 ber, standing on the Pistil, that is, on the margin 

 of a gland crowning the Germen. Stamens definite, 

 distinct, inserted into the same part, as many as 

 the Petals, and alternate with them. Germen 

 single' (scarcely so in the 60th Order). " Styles se- 

 veral, definite. Stigmas as many. Seeds as many, 

 naked, or rarely in a Pericarp, the number of whose 

 cells ansivers to the Styles. Embryo minute, oblong, 

 in the upper part of a hard Albumen. Flowers um- 

 bellate (48:7), with or without a general or partial 

 Involucrum, or both." 



The Germen is considered single, because the Sta- 

 mens are epigynous ; and in fact the Receptacle of
