PERICARP. 



The segments of the stigma are Revolute, 

 rolled back, in Leontodon, fig. 2 ; « Convolute, 

 rolled together, in Crocus. 



Of the Pericarp, or Seed vessel, there are 

 nine principal varieties : 



1 . The Capsule, a dry and hollow case, naturally 

 dividing into several partitions on the ripening 

 of the seeds. It is termed bivalved, when 

 splitting into two parts, as in Pimpernel, 

 (Anagallis) fig. 1, pi. 12 ; trivalved, splitting 

 into three parts, as in Violet, fig. 2, &c. 



The interior of the Capsule either consists 

 of a single cavity, as in Mouse-ear-chickweed, 

 (Cerastium) fig. 3, when it is termed unilocular ; 

 or is divided into cells or compartments, when it 

 is called, according to the number of those cells, 

 bilocular, trilocular, &c. figs. 4, 5, pi. 12. The 

 dissepiments, or partitions which form the cells, are 

 either parallel to the valves, as in Whitlow-grass, 

 (Draba) fig. 6 ; or across, as in Shepherd's Purse, 

 (Thlaspi) fig. 7. 



2. The Silique, or pod, consisting of two valves 

 with an internal partition, along both edges 

 of which the seeds are alternately ranged, as 

 in the Wall-flower, fig. 8.
