Longitudinal section through fruit and seed, (st) stylar prominence, (pi) placenta, (ch) chalaza on closely adherent seed within fruit. X2i approx. spicuous marginal prominence. The stylar prominence is broad, flattened terminal on the crested margin and pierced by a flat canal o-i mm. broad ; the attachment or funicular prominence is recurved away from that of the style, subapical, terminal on the rounded margin. Pericarp o-i mm. thick along the crest, 0*05 mm. thick on the rounded margin, hard, woody formed of compact parenchyma, the cells on the external surface measuring about 0*012 to 0*016 mm. in diameter and in sections of the wall showing a radial alignment. Locule lining of approximately hexagonal cells about 0*025 mm- broad and 0-05 mm. long, their longer axes diverging from the placental region giving rise to obscure divergent striae. Dehiscence occurs along the crested margin. Seed solitary, pendulous from the subapical placenta which immediately underlies the funicular prominence, the funicle being short and thick. Dimensions of fruit in plane of symmetry, 1*7 by 1*5 mm. ; thickness at right angles to plane of symmetry, 1 mm. Length of funicular prominence, 0-17 mm. Seed: Campylotropous, chalaza conspicuous, subcircular, 1-2 mm. in maximum diameter contiguous with the hilum but on the far side of i
