The stigmas and the distal part of the style break off soon after fertilisation while the basal part of the style remains. The wall of the pericarp consists of a thin fleshy outer layer and a hard inner layer, and the fruit is consequently a drupe- let, as in the other species. Sometimes both carpels of a flower are fertilized and grow out as fruits (Fig. 14 b and c), but gener- ally one is abortive (Fig. 15 and 16). As I have had only herbarium material at hand, I cannot say how the embryo develops. On making a section through a fruit, we find a fully grown embryo with a long cotyledon, a short axis and no primary root. This embryo bursts the apex of the pericarp (fig. 146) and appears as a little seedling (fig. 14 c), which by and by becomes larger. For a long time it remains attached to the mother plant. The figures show two different stages; in the first (fig. 15b) the pericarp has been cleft longitudinally to show the base of the seedling inside the pericarp. The first leaves of the seedling have a minute blade and a large sheath, but gradually the size of the blades in- creases and at last we find, still attached to the apex of the mother shoot, a new shoot 6—10 cm long and with well devel- oped foliage leaves; the apices of these ^'leedSg" "stTad": leaves are always truncate and blunt hering to the mother (Fig. 16 a). At a certain moment the ftJ^SSffi-'Si new plant (the seedling) is loosened from involucrum; x, of the the mother shoot, but it takes the peri- $£&££££& carp along with it, and now the pericarp bury, W. A. (3/4 nat size). begins to alter, the fleshy outer part de- caying while the hard inner layer remains. The hard parts of the four lobes become divided into many parallel bristles, and only now does it really deserve its name of a "comb" (Fig. 16ft). The dark green see
