upon their walls, or also upon a mediate replum and 

 placenta, as in the proper Siliquose plants with the poppies, 

 Resedae, Primulae and pinks. 



1292. The reticular-leaf is perfected into a capsule, 

 where the carpels are so confluent with each other, that 

 they form septa and bear the seeds upon the internal 

 angle or upon the axis, as in the Rues. If these car- 

 pels separate, then poly carpal plants, as the Ranuncu- 

 lacese, Malvaceae, Magnoliacese, originate. In these the 

 median columella is the elongated floral peduncle. If 

 they separate, without leaving a median columella be- 

 tween them ; they are then simply called follicles, as in the 

 larkspur and celandine. If this capsule be compressed 

 flat ; it is called legumen, as in the beans. 



1293. The cariopsis generally contains one and that 

 a large seed ; the siliqua or hollow capsule is many- or 

 small-seeded ; the follicle few- or moderately-seeded ; the 

 capsule many- and also few-seeded. 



1294. In the cariopsis the seed is attached to the 

 base or apex ; in the follicle in a row upon the inner 

 suture ; in the siliqua upon the carpellar edges, or their 

 walls, and on a meso-replum or frame ; in the capsule 

 upon the inner angle or on a middle axis or column. 

 Seed-bearing alae to the columella are only the carpellar 

 edges prolonged into the loculi or cells. 



STYLE. 



1295. What the stamen-filament is for the petal of 

 the corolla, that is the style for the ovarial petal or the 

 carpel, viz. the rib that has become free. As, however, 

 the leaf-formation in the ovary is generally imperfect, so 

 also is the separation of the tissues or systems. The 

 style is not therefore freed at once from its root, but 

 projects only above the leaf-substance. 



1296. But as the singular circumstance occurs in the 

 ovary that the mid-rib is arrested while only the margi- 

 nal ribs shoot out, so is the style the elongation and coa- 

 lescence of the two marginal ribs. Every stigma is 

 therefore biacuininate.
