THE SILIQUA AND LEGUMEN. 223 



means necessary to be esteemed otherwise than a sort 

 of capsule. 



2. Siliqua^f. 180, a Pod, is a long dry solitary seed-ves- 

 sel of two valves, separated by a linear receptacle, 

 along each of whose edges the seeds are ranged alter- 

 nately, as in the class Tetradynamia. See Cherian- 

 thus, Engl. Bot. t. 462, and Cardamine^ t. 80 ; also 

 Bignonia eclmiata, figured by Gaertner, t. 52, f. 1, 

 which, though cautiously called by him a capsula slli- 

 quosa only, is as true a Sil'qua^ according to his own 

 definition, and every body's ideas, as possible ; so is 

 also that of Chelidonium, He justly indeed names the 

 fruit of Paonia capsula legiiminosa^ a follicle with him 

 being a single-valved capsule, with the seeds marginal 

 as in a legume. 



Silicula^f. 181, a Pouch, is only a Pod of a short 

 or rounded figure, like Draba vernUj Engl, Bot. t. 

 586. (110) 



3.' Legumen^f. 182, a Legumje, is the peculiar solitary 

 fruit of the Pea kind, formed of two oblong valves, 

 wiihout any logitudinal partition, and bearing the 

 seeds along one of its margins only. See Engl. Bot. 

 t. 1046, 805, &c. The Tamarind is a Legume filled 

 with pulp, in which the seeds are lodged. The Cap- 

 sules of Helleborus and some other plants allied there- 

 to, justly indicated by Gsertner as approaching very 

 nearly to the definition of Legumes, differ essentially

 Siligua, the Thlas/ii, or Shepherd's Purse, of the Silicula.']
