FIGURE. 3. The Gustavia clade. A–D. Gustavia augusta (see Mori, 1995 for vouchers). E–F. G. hexapetala (see Mori & Prance, 1993 for vouchers). F. G. elliptica (see Mori & Lepsch-Cunha, 1995 for vouchers). G. G. longifolia (Cornejo 8092). A. Actinomorphic flower (note that the stamens arise from the rim of a broad, thin-walled staminal tube, a combination of features found only in this clade) and leaves. B. Seed with aril. At maturity the seed is black and the aril is yellow. Only a few species have a conspicuous aril such as found in this species. C. Fruit. The fruit is indehiscent. D. Longitudinal section of an androecium. E. Cross-section of an ovary. Note that the ovary is 6-locular and alate—within the Gustavia clade, these are features found only in a group of species related to the G. hexapetala group. F. Lateral view of a fruit of G. hexapetala. G. Stamen with poricidally dehiscent anther, a character found only in this clade. H. Medial longitudinal section of an ovary. Note that the ovules are inserted on apical, expanded placentae, features found only in this clade. Drawings A–C by B. Angell, D–E by C. A. Gracie, F by A. Tangerini, and G by C. Carollo Matos.
