64 THE FRUIT. 
by dissepiments (85, c) into many cells. The central pillar, or 
substance formed by the united placente is called the colu- 
mella. 'To this the seeds are generally attached. The seed- 
vessels of the Lobelia, mullein, pink, poppy, bloodroot (San- 
guinaria), are capsules. 
FIG. 17.— Forms of fruit: 1, capsule of Rhododendron; 2, Nicotiana; 3, Colchicum; 
4, Gnothera; 5, silique of Raphanus; 6, silicle of Capsella; 7, legume of the pea; 8, jointed 
legume (loment) of Desmodium; 9, follicle of Apocynum; 10, nut of oak; 11, drupe of 
Cerasus. 
2. Striqur (a pod). ‘This is a long, narrow pericarp of two 
valves, divided into two cells, by a false dissepiment formed by 
the extended placente. The seeds are attached to the edges 
of this dissepiment, alternating with its opposite sides. Ex. 
mustard, wallflower, and other Crucifere. 
3. Sizicie (a little pod), differs from the silique, by being 
shorter, and more nearly oval. Ex. pepper-grass, shepherd’s 
purse (Thlaspi). The silique and silicle are poaiiet to plants 
with cruciform corollas. 
4. LrecumeE (also a pod), two-valved, one-celled, consists of a 
simple carpel, and thus differs essentially from the silique. It 
bears its seeds attached to the margin of each valve alternately, 
along the ventral suture only. Ex. pea, and all other plants of 
the great natural order Leguminose. The legume, therefore, 
accompanies the papilionaceous corolla. 
5. Fouuicie (a bag) is a pericarp with one valve and one
