POLYGAMIA. 3g.S»- 



Sedum. Coriaria and Ailanthus, having often united 

 flowers, are best in the 10th Class, as Euclea in the 

 11th. I find no genera truly icosandrous here^ 

 though Schreber esteems Flacourtia and Hedycarya 

 to be so. 



3. Monadelphia. 7gx?/5. ?. 74 ^^ and perhaps /«mj&erw5's 

 t. 1100, albO the exotic Ephedra^ are legitinriate ex- 

 amples of this Older. Spurious ones are Nepenthes, 

 Myristica the Nutmeg, and Schrcber's Xanthe, all 

 placed by him in the now abolished Order Syngenesia^ 

 and which can only take shelter here while the Class 

 remains as it is, for they have no difference of struc- 

 ture in the accessory parts of their flowers. 



Class 23. Polygamia. Stainens and Pistils separate 

 in some flowers, united in others, either on the same? 

 plant or on two or three distinct ones ; such differ- 

 ence in the essential organs being moreover accom- 

 panied with a diversity in the accessory parts of the 

 flowers. Orders 3, 



1. Monoecia. United flowers accompanied with barren 

 or fertile, or both, all on one plant, Atr'iplex, EngL 

 Bot. t. 261, 232, &c., is an instance of this, havino^ 

 the barren flowers of 5 regular spreading segments, 

 the united ones of 2 compressed valves, which, be- 

 coming greatly enlarged, protect the seed. In sever- 

 al species however the flowers are none of them unit- 

 ed, each having only stamens or only pistilso 

 Throughout the rest of the Order, as it stands in Lin= 

 ii^us and Schreber, I can find no genus that has the
