the calyx. Samolus.
Free, inadhcerens, supera. Not united with the calyx or
perigonium. Lilium, Papaveraceae, Caryophyllese.
^ Opening outwards, exterius dehiseens. Lilium, Orchis,

Nigella Hispanica, Saxifraga. PI. 16, fig. 24.
Opening by the teeth, dentihus dehiseens. Statice, Primula
officinalis, Silene.
Opening by cracks, Jissuris dehiseens. Canna,~Epidendron.
Opening by holes, foraminihus dehiseens. Antirrhinum,
in which the holes are irregular, and produced by the rupture
of the sides of the pericarp. Papaver, in which the
holes are regular, and produced by the gaping of the upper
part of the valves. Ledum, Campanula. PI. 16, fig. 31.
Opening at top, apiee dehiseens. Antirrhinum majus,
Papaver.
Opening at bottom, hasi dehiseens. Ledum, Campanula
rigida, Fumaria bulbosa. PI. 16, fig. 25.
Septifragal, septifraga. Opening opposite the partitions.
Saxifraga, Ipomsea purpurea. PI. 16, fig. 29.
Septicidal, septieida. Opening between the cells, the
cells parting from one another, the partition splitting into
two flakes, one of which remains attached to each valve.
Rhododendrum Ponticum. PI. 16, fig. 27.
Loculicidal, loculicida. Opening in the middle of the
cells. Irideae. PI. 16, fig. 26.
If a one-celled capsule, having parietal placentaria,
opens so as to divide the latter longitudinally, the dehiscence
is analogous to the septicidal ; but if it divides into two or
more valves, each furnished with a parietal placentarium
in its middle, the dehiscence is analogous to the loculicidal.
