DIFFERENT KINDS OF PERICARPS. 



1 en different sorts of Pericarps, or Seed-vessels, are enumerated by botanists. 



I. Drupe (Drupa), is a pulpy seed-vessel... encompassing a stone, or nut. 



II. Pome (Pomum), is a pulpy seed-vessel... not enclosing a stone, or nut.. .in the middle of 



which are radiated cells for the reception of seeds. 



III. Berry (Bacca), is a pulpy seed- vessel... without radiated cells in the center... having the 

 seeds irregularly dispersed throughout the pulp. 



IV. Follicle (Follicalus) , is a membranous seed-vessel... of one valve... opening longitudinally, 

 i. e. on the side... and having no apparent suture for fastening or attaching the seeds 

 within it. 



V. Silique (Siliqua), is a membranous seed-vessel... of two valves, with a dissepiment inter- 



vening... seeds attached alternately to the upper and under sutures... seed-vessel longer 

 than broad... flowers cruciform. 



VI. Silicle (SUicula), has the same definition as the last... except that the seed-vessel is 

 rather broader than long. 



VII. Legume (Legnmen), is a membranous seed-vessel... of two valves... no dissepiment... seeds 

 attached to the superior suture only... flowers papilionaceous. 



VIII. Capsule (Capsu/a), is a membranous seed- vessel... varying in the number of valves... 

 without the characters of Pericarps IV. V. VI. VII. as defined above... splits in a deter- 

 minate manner into valves. 



IX. Nut (Nux), a hard stone, or shell, enclosing a kernel... but without a pulpy covering, 

 in which case it would be a Drupe. 



X. Strobile (Strobilus), is a seed-vessel composed of ligneous scales, which embrace the seeds 



within their bosom. 



Terms applicable to the different Pericarps. 



Valves {Valvule) y the external pieces forming the sides of the seed-vessel. .. Sutures (Suturte), 

 the edges, or margins, by which the valves are connected... Column {Columella), a central point 

 of union of the partitions in the seed- vessel... Partitions (Dissepimenta) , the divisions of the seed- 

 vessel into cells... Cells (Loculamenta), hollow places for the reception of the seeds... One-seeded 

 (Monospermus)... Two-seeded (Dispermus), and so on.
