. Bulletin of the scientific laboratories of Denison University. . Fig. 4. Figure 6 is the empirical formula for the flower. The perianth is composed of two circles of three members each. Stamens six, in two circles. Pistil composed of three carpels with dorsal sutures at the angles. Placentation central in three cells. Dehiscence loculicidal. There is perfect symetry and perfect alternation of parts on the plan of 3. Figure 7 is a view of the cross section of the ovary, twice size. There are six fibro-vascular bundles. ^^-S- The three at the angles represent the midribs of the carpel leaves.

There is perfect symetry and perfect alternation of parts on the plan of 3. Figure 7 is a view of the cross section of the ovary, twice size. There are six fibro-vascular bundles. ^^-S- The three at the angles represent the midribs of the carpel leaves. The three opposite the faces are the united bundles of the two united half blades. At dehiscence the bundles at the angles are divided, the separation taking place through the middle of each bundle into the loculi. The partitions are formed by the infolded edges of the carpel leaves. Each leaf is completely rolled in and each margin bears a row of carpels. From the stigma and from the strongly developed fibro-vascular bundle in the middle of each face it would appear that the latter was the midrib and the dehis- cence down the ventral suture in which case the ovules would probably be con- sidered as lateral axial and so morpholog- ically leaves. That this is not the case is very clearly shown by the ex- amination of the empirical diagram. Fig. 8 made from a flower in which the pistil is ruptured along the lines of its regular dehiscence, but long before its maturity and there is de- ^^^' ^" velopcd a circle of perfect stamens on what must evidently be considered a prolongation of the.
