FIGURE 2. The Grias clade. A–D. G. longirachis (Clark & Mori, 2000 for vouchers). E–J. G. purpuripetala (see Mori et al., 2010 for vouchers). A. Apical view of a flower. All species of this clade have four petals. B. Medial longitudinal section of a flower. All species of this clade have a thick and fleshy staminal tube with a lower and an upper chamber. In this species the lower chamber is very short. C. Cross-section of an immature fruit. All species of this clade have endocarp buttresses and usually have 4-locular ovaries. D. Fruit on the right and seed on the left. Note the endocarp buttresses showing in this dried fruit and the single seed with a very fragile seed coat. E. Large leaf characteristic of all species in this clade. F. Apical view of a flower on the left and cross-section of an ovary on the right. This flower is 3-locular but most likely it is a variant from the normal 4-locular ovary common to species of the genus. G. Medial longitudinal section of the androecium showing the stamens and the upper and lower chambers of the staminal tube. In this species the lower chamber is well developed. H. Medial longitudinal section of an ovary. All species of this clade have a few pendulous ovules from near the apex of the septum. This species appears to have a ring nectary but this characteristic is not apparent in all species of the clade. Drawings by B. Angell.
