3 ON SYSTEMS AND CLASSIFICATIONS. 



are distinguished according as the root is either hbrous or bulbous. 

 The eleventh, twelfth, and thirteenth classes contain the compound 

 flowers ; the twelfth, semifloscular flowers ; the thirteenth, discoid 

 flowers. The fourteenth class contains such plants as bear several 

 capsules together, as the ranunculus, anemone, &c. The last class 

 includes Mosses, Algae, Fungi, and Filices. The ancients believed 

 that these plants produced neither flowers nor seeds. 



Morison constructed his system according to the flower, and the 

 external appearance of the plant. He has eighteen classes: 



1. Lijmosae, Arbores. 



2. Fjutices. 



3. Suffrutices. 



4. Herbaceae, Scundenles. 



5. Leguminosae. 



6. Siiiquosae. 



7. _ . Tricapsulares. 



8. : a numero capsularum dictae. 



9. Corymbiferae. 



10. Lactescentes. s. papposae. 



1 ] , Culmiferae s. Calmariae. 



12. Umbeiliterae. 



13. Tricoccae. 



14 # Galeatae. 



15. Multicapsularcs. 



16. Bacciferae. 



17. Capillares. 



18. Heteroclitae. 



The defect of this system, as of all the old systems, consists in the 

 various foundations of the division, and in separating trees and 

 plants. By auffrutices. Morison means small shrubs, but not ac- 

 cording to the modern definition. Even some moderns use the term 

 Suffrutex for a small shrub. The fourth class contains all twining 

 plants, as the Cucurbita, Convolvulus, &c. The seventh class in- 

 cludes plants which have a trilocular capsule. In the eighth class 

 are plants that have sometimes more, sometimes fewer cells in the 

 capsules. The ninth class contains the compound flowers that have 

 no pappus, or at least only a membranaceous one. In the tenth 

 class are all the compound flowers that have a plumose, pilose, seta- 

 ceous, &c. pappus. To the eleventh class belong all the grasses
