SYNOPSIS OF GENERA. 



2-seeded, imbricate in a cone, not opening, attenuated. Magnoliacea, 

 p* 15. 



ASIMINA. CaL 3-parted. Pet* 6, spreading, ovate-oblong ; the in- 

 ner smaller. Anth. subsessile. Ber. several, ovate, sessile, many- 

 seeded. Anonacea, p. 16. 



HYDROPELTIS. CaL of 34 sepals. PeL 34. Ovaries 618' 

 Seeds pendulous, ovate, globose . Hydropeltidece, p. 18. 



NELUMBIUM. Col. petaloid, of 46 sepals. Pet. numerous. Carp. 

 numerous, deeply immersed in the upper surface of a turbm&te receptacle 

 or torus, 1-seeded. Nymplweacece, p. 19. 



OBS. The remaining genera belong to the Order Ranunculacea, 

 p. 3. 



DlDYNAMIA. 



2 orders. 1. Gymnospermia. Seeds naked. 



2. Angiospermia. Seeds in a capsule. 



OBS. The genera of this class form a very natural group, hav- 

 ing irregular or bilabiate flowers, with mostly 4 stamens (2 longer) ; 

 but sometimes 2 are abortive, and hence such are arranged artificially 

 in the class Diandria. The whole will be more easily, as well as cor- 

 rectly studied, by the natural orders. The genera belonging to the order 

 Gymnospermia will be found among the Labiate, p. 270 ; those belong- 

 ing to Angiospermia among the Orobanchece, p. 260, Scrophularinece, p. 

 261, and Ferbenacece, p. 283. 



TETRADYNAMIA. 



OBS. This class is entirely natural ; and it is therefore altogether 

 unnecessary to repeat the generic descriptions. It is identical with the 

 natural order Crucifera, p. 24. I have chiefly for the sake of conven- 

 ience, preserved the Linnasan division into Siliculosce and Siliquosce. 

 Gynandropsis and Polanisia, ( Cleome Linn. ) usually arranged under 

 this class, form the order Capparidece, p. 34. 



MONADELPHIA. 



PENTANDRIA. 



PASSIFLORA. CaL 5 -parted, coloured. Pet. 5, or none, inserted in- 

 to the calyx. Nect. a filamentous crown. Ber. pedicelled. Passiflo- 

 rea, p. 129. 



DECANDRIA. 



GERANIUM. Sep. 5, equal. Pet. 5, equal, 5 alternate stant. long- 

 er, with nectariferous scales at the base. Fruit beaked, separating into 

 5 1-seeded capsules, each with a long naked simple awn. Geraniace& t 

 p. 67. 



POLYANDRIA. 



OBS. The genera of order from the Natural Order Malvaceae, p. 56. 

 DlADELPHIA. 

 HEXANDRIA. 



OBS. The succeeding genera belong to the Natural Order Fumaria- 

 eea, p. 22,
