them. This paper abounds with copious and most 

 valuable critical remarks on the differences or affinities 

 of particular genera. 



CLASS 11. DICOTYLEDONS. COROLLA MONOPE- 

 TALOUS, EPIGYNOUS. ANTHERS DISTINCT. 



"Proper Calyx" (Perianth, 53: 1) " of 1 leaf, su+ 

 perior. Corolla of 1 petal, rarely of several united 

 by their broad bases, superior, often regular. Sta- 

 mens definite, inserted into the Corolla, with distinct" 

 (distant or divaricated) " anthers. Germen simple. 

 Style usually one, sometimes several, or wanting. 

 Stigma simple or divided. Seed, or generally Pe- 

 ricarp, either capsular or pulpy, inferior, of 1 or 

 many cells, with 1 or many Seeds." 



Jussieu makes the separate Anthers the difference 

 between this Class and the last, speaking of the pre- 

 sent (so far, we must presume, as it consists of aggre- 

 gate Flowers,) as rather superfluous. But the disposi- 

 tion of the vessels of the Corolla, noticed by Mr. Brown 

 in the former Class, affords a decisive distinction. 



Ord. 56. DIPSACE;E. " Calyx single or double. 

 Corolla tubular, with a divided limb. Stamens defi- 

 nite. Style and Stigma simple. Capsule generally 

 single-seeded, not bursting, but resembling a naked 

 Seed ; very rarely composed of 2 or 3 single-seeded 

 cells. Albumen none. Radicle superior. Stem usually 

 herbaceous. Leaves opposite, rarely whorled. Flow- 

 ers in a few instances distinct, in most aggregate, on
