280 THE SILiaUA. 



Coccum of Gaertner, separated by him 

 from capsules, is a dry seed-vessel, more 

 or less aggregate, not solitary, whose sides 

 are elastic, projecting the seeds with great 

 force, as in Euphorbia ; also Boro?iia, 

 Tracts on Nat* History, t. 4 — 7» This 

 seems by no means necessary to be esteemed 

 otherwise than a sort of capsule. 

 2- Siliqua, a Pod, is a long dry solitary 

 seed-vessel of two valves, separated by a 

 linear receptacle, along each of whose 

 edges the seeds are ranged alternately, as 

 in the class Tetradynamia. See Cheiran- 

 thtis, Engl. Bot. t. 462, and Cardamine, 

 t. 80 ; also Bignonia echinata, figured by 

 Gaertner, t. 52. f. 1, which, though cau- 

 tiously called by him a capsula siliquosa 

 only, is as true a Siliqua, according to his 

 own definition, and every body's ideas, as 

 possible ; so is also that of Chelidonium. 

 He justly indeed names the fruit ofPceonia, 

 capsula leguminosa, a follicle with him 

 being a single-valved capsule, with the 

 seeds marginal as in a legume. 



Silicula, a Pouch, is only a Pod of a 

 short or rounded figure, like Draba verna, 

 Engl Bot. t. 586.
