Fia. 394. — Loment of 
beggar-ticks. 
— The carpellary leaves may 
unite either by their open 
edges, as if a whorl like that 
represented in Fig. 188 were 
to grow together by the 
margins (Fig. 395); or each 
may first roll itself into a

these may unite by their ventral sutures into a single syn-

(Fig. 398). The seed-bearing sutures being all brought to- 
gether in the center, the placenta becomes central and azial. 
In the first case (Fig. 395) the open carpels form a one- 
chambered capsule, though the placentas sometimes project, 
as in the cotton, so far as to produce the effect of true 
partitions with a central axial placenta. In capsules with
