408 SYSTEMATIC BOTAKT, OR 



Class 1. Monandria, includes all such plants which have but 

 one stamen to the flower, as Hippuris, Centranthus, 

 &c. (Fig. 481.) 



Class 2. Diandria, those plants which have two stamens in the 

 flower, as the Ash, Lilac, Privet, &c. (Fig- 426.) 



Class 3. Triandria^ those with three stamens, as most Grasses, 

 Valerian, Iris, &c. {Fig. 488.) 



Class 4. Tetrandria, those with four stamens, as the Holly, 

 Plantain, AlcheviiUa, &c. (Fig. 846.) 



Class 5. Pentandria, those with five stamens, as the Cowslip, 

 Convolvulus, Campanula, Nightshade, &c. (Fig. 

 506.) This is a very extensive class. 



Class 6. Hexandria, those with six stamens, as the Lily Order 

 of the Natural System, &c. {Fig. 510.) 



Class 7. Heptandria, tliose with seven stamens, as the Horse- 

 chestnut, Trientalis, &c. {Fig. 888.) 



Class 8. Octandria, those with eight stamens, as the Heath, 

 Ivy, Paris, &c. (Fig. 564.) 



Class 9. Enneandria, those with nine stamens, as the Flower- 

 ing Rush, Rhubarb, &c. {Fig. 575.) 



Class 10. Deccwdria, those with ten stamens, as the Pink, 

 Saxifrage, &c. {Fig. 872.) 



Class 11. Dodecandria. This class includes all plants possessing 

 the characters above described, which have flowers 

 containing from twelve to nineteen stamens, as 

 the Asarabacca, Mignonette, &c. 



The two succeeding classes include plants with hermaphrodite 

 flowers, having twenty or more unconnected stamens, which 

 vary as to their mode of insertion ; but the names of the classes 

 are not here exactly descriptive. Thus : — 



Class 12. Icosandria, (literally twenty stamens). This includes 

 all plants which have twenty or more stamens to 

 the flower, and inserted on the calyx or pcrigynous, 

 as in the Rose Order, &c. {Fig. 448.) 



Class 13. Po/j/a7?(/r/a, (literally many stamens), those which have 

 twenty or more stamens inserted on the thalamus 

 or receptacle — that is hypogijnous ; as in the But- 

 tercup, Poppy, Anemone, &c. {Fig. 883.) 



The characters of the two succeeding classes depend upon the 

 relative length of the stamens, the flowers being also lierma- 

 phroditc; thus: — 



Class 14. Didt/vawia, includes ])lants with four stamens to the 

 flower, two of which are long and two short, — or, 

 in other words, didyuamons, as in the Snapdragon, 

 Dead-nettle, &c. {Fig. 547.)
