PERICARP. 115 



564. Tryma, a kind of dryish drupe, 2-coated, the epicarp fibro- 

 fleshy (butternut) or woody (hickory), the nucleus bony with its cell 

 often deeply 2-parted (cocoa-uut). 



565. Et^erio, an aggregate fruit consisting of numerous little drupes 

 united to each other (raspberry) or to the fleshy receptacle (black- 

 berry). 



566. Berry, a succulent, thin-skinned pericarp holding the seeds 

 loosely imbedded in the pulp (currant, grape). 



567. Hesperidium a succulent, many-carpeled fruit, the rind thick, 

 leathery, sep-irable from the pulpy mass within (orange, lemon). 



568. Pepo, an indehiscent, compound, fleshy fruit, with a hardened 

 rind and parietal placentae (melon). 



569. The pome is a fleshy, indehiscent pericarp formed of the per- 

 manent calyx, containing several cartilaginous (apple) or bony (haw) 

 cells. 



570. The pyxis is a many-seeded, dry fruit, opening like a lid by 

 a circumcissile dehiscence (plantain, henbane, Jeffersonia). 



571. The follicle is a single carpel, 1-celled, many-seeded, opening 

 at the ventral suture (columbine, larkspur, silk grass). 



572. The legume or pod is a single carpel, 1-celled, usually splitting 

 into two valves, but bearing its 1-go seeds along the ventral suture only, 

 in one row, as in the bean and all the Leguminosae. It is sometimes 

 curved or coiled like a snail-shell (Medicago). 



573. The loment is a jointed pod, separating across into 1-seeded 

 portions (Desmodium). 



574. Silique. This is also a pod, linear, 2-carpeled, 2-valved, 2- 

 celled by a false dissepiment extended between the two parietal pla- 

 centa?. To this false dissepiment on both sides of both edges the 

 seeds are attached (mustard). 



575. Silicle. This is a short silique, nearly as wide as long (shep- 

 herd's purse). The silique and silicle are the peculiar fruit of all the 

 Cruciferae. 



576. 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). 



577. The regma is a kind of capsule like that of the Geranium, 

 whose dehiscent carpels separate elastieally but still remain attached 

 to the carpophore. 



578. 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). 



579. The cone (syncarpium, gvv, together) of the Magnolia tribe
