FORMS OF THE PERICARP.

edges the seeds are attached (Mustard). The silicic is a short 

 silique, nearly as wide as long (Shepherd's Purse). The silique 

 and silicle are the peculiar fruit of all the Crucifene. 



167. Capsule (casket.) This term includes all other forms of 

 dry, dehiscent fruits, compound, opening by as many valves as 

 there are carpels (Iris), or by twice as many (Chickweed), or by 

 pores (Poppy). 



168. The Regma is a kind of capsule like that of the Gera- 

 nium, whose dehiscent carpels separate elastically, but still 

 remain attached to the carpophore. 



169. Strobile, or Cone; an aggregate fruit consisting of a 

 conical or oval mass of imbricated scales, each an open carpel 

 ( $ flower), bearing seeds on its inner side at base, i. e., axillary 

 seeds (Pine and the Gymnosperms generally). The Cone (syn- 

 carpium, tfuv, together) of the Magnolia tribe is a mass of con- 

 fluent, closed pericarps on a lengthened torus (Cucumber Tree).

1W, Strobile of Finns. 195, The Tip: Csyconus). 196, Sorosis of Mulberry. 197, Hip of Kosa, aclienin 

 nearly enclosed in the leathery calyx tube. 



170. The Fig (syconus) is an aggregate fruit, consisting of 

 numerous seed-like pericarps enclosed within a hollow, fleshy 

 receptacle, where the flowers were attached. 



171. Other confluent fruits (Sorosis) consist of the entire in- 

 florescence developed into a mass of united pericarps, as in the 

 Mulberry, Osage-orange, Pineapple.
