. A class-book of botany, designed for colleges, academies, and other seminaries ... Illustrated by a flora of the northern, middle, and western states; particularly of the United States north of the Capitol, lat. 38 3/4. Botany; Plants -- United States; Plants -- Canada. 64 THE FRUIT. by dissepiments (85, c) into many cells. The central pillar, or substance formed by the united placentas is called the colu- mella. To this the seeds are generally attached. The seed- vessels of the Lobeha, mullein, pink, poppy, bloodroot (San- guinaria), are FIG. 17. — Forms of fruit: 1, capsule of Rhododendron; 2, Nicotiana; 3, Colchicum; 4, (Enothera; 5, silique of Raphauus; 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. SiLiQUE (a pod). This is a long, narrow pericarp of two valves, divided into two cells, by a false dissepiment formed by the extended placentae. The seeds are attached to the edges of this dissepiment, alternating with its opposite sides. Ex. mustard, wallflower, and other Cruciferas. 3. Silicle (a little pod), differs from the siHque, by being shorter, and more nearly oval. Ex. pepper-grass, shepherd's purse (Thlaspi). The silique and silicle are pecuHar to plants with cruciform corollas. 4. Legume (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 Leguminosae. The legume, therefore, accompanies the papilionaceous corolla. 5. Follicle (a bag) is a pericarp with one valve and one.
