FIGURE 4. The Lecythis pisonis clade (see Fig. 101 in Mori & Prance, 1990 for vouchers). A. Flower with an open androecial hood. B. Medial longitudinal section of flower with flat androecial hood. The androecial hood possesses a proximal group of staminodes for about one-quarter of its length (not distinguishable in this image) and vestigial stamens for the rest of the length. C. Medial longitudinal section of ovary. Note the stylar collar located just under the stigma. D. Cross-section of 4-locular ovary. E. Operculum with a woody columella that projects into the fruit. F. Fruit base. The fruits of this clade are the largest of all Lecythidaceae. G. Sulcate seed with a long basal aril. Note the funicle projecting from the bottom of the aril. Drawing by B. Angell.
