Pericarp of Mignionette open soon after flowering. 421, Naked seed of Taxus Canadensis, surrounded, not covered by the fleshy pericarp. the birch is 2-celled, 2-ovuled ; but by the suppression of one cell with its ovule, the fruit becomes 1-celled and 1-seeded. 546. On the other hand the cells are sometimes multiplied in the fruit by the formation of false partitions. Thus the pod of thorn-apple (Datura) becomes 4-celled from a 2-celled ovary, and tlio longer pods of some leguminous plants have cross- partitions formed between the seeds. 426 427. 428 425 424 423 Capsule, 427, of Scrophularia, 2-celled ; 425, of Datura Stramonium ; 425, of Iris; 426, show- ing its mode of dehiscence (loculicidal); 424, of Colchicum, 3-celIed. 428, Eegma, ripe fruit of Geranium, the carpels (cocci) separating from the axis and bending upwards on the elastic style*. PERICARP. The fruit consists of the pericarp and the seed. 541. The pericarp (nepi, around) is the envelope of the seeds, con- sisting of the carpels and whatever other parts they may be combined with. It varies greatly in texture and substance when mature, being.
