II, p. 189. Shows two posterior bundles (PP). One staminal trace (S), with the inversely orientated bundle (L), has arisen by the branching into three portions of one of the posterior bundles. X 18.—As 17, but higher up in the axis. Here the bundle L is at its fullest stage of development, above this level it dies away. X 19.—Transverse section through one of the bundles supplying the axis of the female flower as it passes out through the cortex of the rachis. Here it is clearly concentric. X 116. Syke<s, Phil.
