THE SILIQUA. 213 



or two cells, never bursting, but falling off entire, 

 and dilated into a kind of wing at the summit or 

 sides. It is seen in the Elm, the Maple, the Ash, 

 EngL Bot. t. 1692, and some other plants. This 

 term however may well be dispensed with, especially 

 as it is the name of a genus in Linnaeus ; an objec- 

 tion to which Cotyledon too is liable. 



Folliculus, a Follicle or Bag, reckoned by Linnaeus 

 a separate kind of seed-vessel from the Capsule, 

 ought perhaps rather to- be esteemed a form of the 

 latter, as Gaertner reckons it. This is of one valve 

 and one cell, bursting lengthwise, and bearing the 

 seeds on or near its edges, or on a receptacle parallel 

 therewith. Instances are found in Vinca, t. 514, 

 P<zonia,t. 1513, and Embothrium, Bot. of New 

 Holland, t. 7 10. 



Coccum of Gartner, separated by him from cap- 

 sules, 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 

 Boronia, Tracts on Nat. History, t. 4 7. This 

 seems by no means necessary to be esteemed other- 

 wise than a sort of capsule. 



12. SUiqua,f. 180, a Pod, is alongdry 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 Tetr adynamia. See C heir ant hits, 

 Bot. t. 462, and Cardamine, t. 80 ; also
