. The elements of botany for beginners and for schools. Plants. SECTION 14.] FRUIT. 123 Poppy, or burs! Irregularly in sonic part, as in Lobelia and the Snapdragon; but commonly il split - open (or \& dehiscent) lengthwise into regular pieces, railed VaLV] 9 371. Regular Dehiscence in a capsule takes place in two ways, which are best illustrated in pods of two or three cells. It is either Loculicidal, or, splitting directly into the loculi or cells, that is, down the hack (or the dorsal suture) of each eell or carpel, as in Iris (Fig. 395) ; or Septicidal, that is, splitting through tin; partitions or septa, as in St. John's-wort ( Pig. 396), Rhododendron, etc. This divides the capsule into its compo- nent carpels, which then open by their ventral suture. 372. In loculicidal dehiscence the valves nat- urally bear the partitions on their middle; in the septicidal, half the thickness of a partition is borne on the margin of each valve. See the annexed diagrams. A variation of either mode occurs when the valves break away from the part it ions, these remaining attached in the axis of the fruit. This is called Septifragaldehiscence. One form is seen in the Morning-Glory (Fig. 400). 373. The capsules of Rue, Spurge, and some others, are both loculi- cidal and septicidal, and so split into half-carpellary valves or pieces. 374. The Silique (Fig. 401) is the technical name of the peculiar pod of the Mustard family ; which is two-celled by a false partition stretched across between two pa- rietal placentae. It generally opens by two valves from below up- ward, and the placentas with the partition are left behind when the valves fall off. I 375. A Silicle or Pouch is only a short and broad silique, like that of the Shepherd's Purse, Fig. 402, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Gray,
