DODECANDRIA. 323 



4. Pentagynia. Abounds in more Catyophylletf, as 

 Lychnis, t. 573, and Cerastium, t. 789, 790. 

 Cotyledon, t. 325, Sedum, t. 1319, and Oxalis, 

 t. 762, are placed here. Some of the last genus 

 have the filaments united at their base, and there- 

 fore should belong to the sixteenth class, another 

 defect in the artificial system. 



5. Decagynia. Consists of only Neurada, with 

 Phytolacca; the latter an irregular genus as -to 

 stamens and styles, which therefore afford good 

 marks to discriminate the species. 



CLASS 11. Dodecandria. Stamens 12 to 19. 

 Orders 6. 



1. Monogyma. A rather numerous and very various 

 order, with scarcely any natural affinity between the 

 genera. Some of them have twelve, others fifteen 

 or more stamens, which should be mentioned in 

 their characters. Asarum, Engl. Bot. t. 1083, and 

 the handsome Lythrum Salicaria, t. 1061, also the 

 American Snow-drop-tree, flalesia, not rare in our 

 gardens, may serve as examples of this order. Ster- 

 culia is very properly removed hither from Gynan- 

 dria by Schreber and Willdenow, as its stamens are 

 not inserted above the germen. 



2. Digynia consists of Hdiocarpus, a very rare Ame- 

 rican tree with a singularly fringed or radiated fruit ; 

 and Agrimonia, Engl. Bot. t. 1335. The latter
