FIGURE 5. The Allantoma clade. A–G. A. lineata (see Prance & Mori, 1979 for vouchers for all but G based on Prance et al. 11618). H– M. A. decandra (H–J based on Ducke, 1925, vouchers not cited; K–M based on Krukoff 7193). A. Entire flower. All species of Allantoma have 5 petals. Note that the petals are curved downward at apices. B. Medial longitudinal section of a flower. Note that the stamens turn downward and that they are inserted both on the rim of the staminal tube as well as on the inside of the tube. C. Cross-section of the ovary. Note that it is usually 4-locular. D. Fruit base. Note that it is cylindrical throughout. E. Operculum with its long, tapered columella (= tackshaped). F. Immature seed. Note that it has a vestigial unilateral seed wing. G. Mature seed. Note that the vestigial wing has disappeared and that there is a notch where it was once attached. H. Bud. I. Bud with petals removed showing the broadly triangular calyx-lobes and the longest stamens. J. Androecium cut and spread open. Note that there are two sets of stamens, an alternating long set and a shorter set, and that both sets arise from the staminal tube rim and curve downward. K. Fruit base. Note that it tapers at the base and is slightly costate (at least when the fruits are dry). L. Operculum with its long columella. M. Mature seed with a well-developed unilateral wing at maturity. Drawings A–F by H. M. Fukuda and G, K–M by C. Carollo Matos. The artist for H–J is not known.
