Discussion:

Portions of a flower of Duidaea tatei are shown in fig. 114. The corollas of this species (fig. 114A) exhibit the simplified type described above for Gongylolepis fruticosa. Although the five corolla-tube veins continue into the achene, fewer than five additional exterior bundles may be present (fig. 114 C, E). Stamen traces unite with the associated corolla veins in the corolla-tube. In the style (fig. 114 B) four bundles are present. The dorsiventral pair of these unites with achene wall bundles in the achene summit. In the flower studied, only one of the lateral bundles was seen to form an interior bundle in its extension into the achene. A simple ovule trace is present, and all of the bundles in the achene unite at the base into a single strand. Duidaea pinifolia was found to have a vasculation pattern like that shown for D. tatei.
