PLATE XI. 



MODES OF FLOWERING continued. 



Vig, 



6. THYRSUS, a panicle contracted into an oval form. 



7. ( CYMA, a cyme ; a mode of inflorescence which differs 



from an umbel, in having the partial footstalks 

 placed without any regular order. 



9. CORYMBUS, a mode of flowering, which, like the pre- 



ceding, resembles an umbel in its general appear- 

 ance, but may easily be distinguished by the unequal 

 length of the footstalks, which do not, as in the 

 umbel, proceed from the same centre, but are 

 produced from different parts on both sides of the 

 stalk. 



10. CAPITULUM, a little head. 



PARTS OF FRUCTIFICATION resumed. 



E PERICARPIUM, OR SEED-VESSEL. 

 1. A Capsule, with an undivided cavity or single cell. 



2. with two cells. 



3. with three cells. 



4. with four cells. 



5. with six cells. 



Fig. 



6. A capsule with many cells. 



7. That species of pod termed legumen, in which the seeds 



are fastened along one suture only. 



8. Folliculus, a species of dry seed-vessel, which opens 



longitudinally on one side from bottom to top, and 

 has the seeds loose within it. 



9. Represents that pulpy kind of pericarpium termed pomum, 



with its inclosed capsule, having five cells, in which 

 are contained the seeds. 



10. Drupa, a pulpy seed-vessel of the Cherry kind, con- 



taining a nut or stone. 



11. The section of a drupa, exhibiting the pulpy part and 



the stone. 



12. A nut or seed covered with a shell. 



13. Strobilus, a cone. 



14. Bacca, a pulpy pericarp without valves, inclosing 



naked seeds. 



15. The transverse section of a bacca, to exhibit the dis- 



position of the seeds within the pulp. 



16. C That species of pod termed siliqua, in which the 



17. < seeds are fastened to both sutures or joinings of 

 (. the valves alternately.
