 valuable critical remarks on the differences or affini- 

 ties of particular genera. 



Class 11. Dicotyledones. Corolla monope- 

 talous, epigynous. anthers distinct. 



"Proper Calyx" {Perianth, 53:1) "of] leaf, su-

 Stigma simple or divided. Seed, or generally Pe-

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
