Open any con- venient specimen and notice the manner of dehiscence. How does it differ from that of the legume '^. What other difference do you perceive.'' Are the edges of the valves reflexed or folded in any way so as to form the two cells or chambers into which the silique is divided.'' How is the partition made.'' A dividing wall of this sort, that is made in any other way than by the inflexed margins of the car- pels, is called a false partition. Sketch your specimen as it appears with one of the valves removed, showing the position and attachment of the seeds. Where is the placenta ? Is the false partition parallel with the valves or at right angles to them ? Compare it in this respect with other specimens of the same family, and with the sihque of the trumpet vine, if you can get one; is the direction of the parti- tion always the same} Does it fall away with the valves or remain attached to the receptacle.' 159 160 159,160. — Silique of mustard: 159, closed; 160, after dehiscence, showing false parti- tion, 102. The Silicle is only a short and broad silique, Hke those of the shep- herd's purse (Capsella bursa-pastoris) and pepper grass {Lepidiimi). The last two named belong to the class known as 161 162 161, 162. — Silicle of shepherd's purse: i5i, entire; 162, with one carpel removed, show- ing attachment of seeds, and the false partition running con- trary to the flattened sides. 103. Syncarpous or Compound Pods. — Generally speak- ing, there are never more carpels in a pod than there are seed-bearing sutures. In a boll of cotton, or a pod of okra, iris, or other large dehiscent fruit, notice the lines or seams running from base to apex of the pericarp ; into how many sections or carpels do they divide it ? When several car- pels unite in this way into one body, they form
