210 JUSSIEU'S NATURAL SYSTEM. 



CLASS XII. EPIPETALE/F.. 



35. Polypetalous dicotyledones, with the petals of a 

 definite number, epigynous, standing on the pistil, that 

 is, on the margin of a gland crowning the gennen. 



The calyx is one leaf, superior ; stamens definite, distinct, epigy- 

 nous, or inserted into the same part, as many as the petals, and 

 alternate with them ; germen single ; styles several, definite ; 

 stigmas as many 5 seeds as many, naked or rarely in a pericarp, the 

 number of whose cells answers to the styles ; embryo minute, oblong, 

 in the upper part of a hard alburnum. Flowers umbellate, with or 

 without a general or partial involucrum, or both. 



36. The eighty-second and eighty-third orders, ara- 

 liacece and umbelltfera;, are the only two divisions of this 

 class ; the former established on the genus aralia, and 

 the latter embracing the umbelliferous plants. 



CLASS XIII. HYPOPETALEJE. 



37. Polypetalous dicotyledones with the pistils hyj>o- 

 gynous, that is, inserted under the pistil, definite ; very 

 rarely indefinite ; mostly distinct, sometimes united at 

 the base into a kind of monopetalous corolla ; rarely 

 entirely wanting. 



Calyx of one or many leaves ; very rarely wanting ; stamens hypo- 

 gynons, definite or indefinite, their filaments usually distinct, but 

 sometimes united into a tube, or more rarely cellected into several 

 bundles ; anthers usually distinct ; germen superior, in numerous 

 instances single, in some multiplied ; style one, or several, or 

 wanting; stigma one or several ; fruit superior, either single, with 

 one or many cells, or more rarely multiplied, each separate pericarp 

 being of one cell.
