FIGURE 7. The Couratari clade. A–H. C. stellata (see Mori & Prance, 1990 for vouchers). I–L. C. oblongiflora (Fróes 1763). A. Androecium. Note the echinate exterior of the androecial hood. B. Medial longitudinal section of an androecium. Note the external flap. C. Lateral view of an ovary with two of the six calyx-lobes removed. Note the stylar collar. D. Cross-section of a 3-locular ovary which is characteristic of all species of Couratari. E. Base of a fruit. F. Operculum. Note the long columella. G. Seed with circumferential wing. H. Seedling with flattened stem and foliaceous cotyledons. I. Androecium. J. Staminal ring. Species of Couratari have fewer stamens than any other species of zygomorphic-flowered Lecythidaceae. Note the staminal ring lip. K. Medial longitudinal section of an androecium. Note the vestigial stamen nectaries at the apex of the coil. Eschweilera sensu lato is the only other genus with vestigial stamen nectaries. L. A stamen. Note the very short filament. Drawings by Bobbi Angell.
