The columbineis, therefore, said to be apocarpous(the carpels not organically united),whereas pistils made up of severalcarpels—that is, compound pistils—are said to be syncarpous 305a. A suture is a juncture, seam, orplace of union. Does the columbineproduce five pods, or may some of the pistilsperish in the struggle for existence ? 3056. Dry dehiscent fruits or pericarpsare known under the general name ofpods. A pod which opens by theventral suture alone, as the columbinedoes, is a follicle. 306. A bean pod isshown in Fig. 248. Itdiffers from the columbinepod in the fact that itopens on both edges,— onboth the ventral and dorsal pod is a This kind of 306a. Do all pods of peas and beans open by both sutures ?Examine the garden peas. In order to determine the manner ofdehiscence of any pod, examine it when fully ripe and dry. 3066. When a fruit dehisces into two or more parts, the sepa-
