FIGURE 4. The Couroupita clade. A–J. C. guianensis. K-L. C. nicaraguarensis. A. Flower (Mori et al. 25755, photos only). B. Medial longitudinal section of an ovary (see Mori & Prance, 1990 for vouchers for B, C, and D). Note that the placentae are located on the septa in the middle of the locule. C. Cross-section of an ovary. Note that the ovary is 6-locular. D. Medial longitudinal section of an androecium. Note that there is an appendage-free area between the staminal ring and the androecial hood. E. A tree showing the cauline infructescences and the cannon-ball shaped indehiscent fruits (unvouchered photo taken in Costa Rica). F. A mature fruit (unvouchered photo). Note the faint ring near the apex of the fruit indicating where the calyx-lobes were attached—this is called the calycine ring. The pimple-like structure in the middle of the apex of the fruit is the remnant style. G. Cross-section of a fruit (see Mori & Prance, 1990 for vouchers for G and H). Note that the interior of the fruit consists of six wedges that represent the six locules of the ovary. H. Medial longitudinal section of a fruit. Note the seeds embedded in the pulp. I. A seedling with expanded foliaceous cotyledons (I and J vouchered by Mori & Kallunki 3263). J. Seedling just after pulling free from the seed coat. Note the foliaceous cotyledons. K. Flower (Hernández et al. 661). L. Medial longitudinal section of an androecium (see Fig. 35 in Mori & Prance 1990 for vouchers). Note there are appendages along the entire length of the ligule and, thus, this species has continuous stamens from the staminal ring to the end of the staminal hood. Line drawings by B. Angell.
