each partition, taken separately, does not divide the hollow
of' the pericarp into two cells. Syringa vulgaris, Citrus,

^ Complete, completa. Dividing the cavity of the pericarp
completely, by being either a general partition itself,
Cheiranthus, or if partial, by touching some other par-
tition.
Incomplete, incompleta. Only dividing the cavity incompletely,
being partial partitions that do not touch one
another, nor abut upon a placentarium. Papaver.
^ Valvean, valveaiia. Formed by the expansion of the
substance of the valves,- and remaining fixed to them, when
the pericarpium splits open.
Median, media?ia, medivQlves, valvis contraria, valv'is medio
sepliferis. Valvean and arising from the middle of the
valves. Lilium, Syringa, Acanthaceee, Polemonium, Helianthemum.
Marginal, marginalia, valvis ulroque margins inlrojiexo
singulis loculum conslilutendbus, valvares. Valvean, and
formed by the edge of the valves, which turns into the
interior of the pericarp, towards a real or imaginary central
axis. Antirrhinum, Rhododendriim, Astragalus.
Two-flaked, hilamellares. Marginal, and formed by the
union of the edges of two contiguous turned- in valves,

Placentarian, placentariana. Produced by the expansion
of the placentarium, or its lobes, so as to reach the internal
surface of the pericarpium, or its sutures, and separate
when the fruit is ripe. Plantaginese, Crucifer^e, Punica
Granatum, Cucurbitacese.
Interposed, interpositiva, valvis margine apposili^ anri^ulis
dissepimenti. Several placentarian partitions diverging
from the centre of a many-valved pericarpium to the sutures,laceae.
so that they alternate with the valves. Convolvu-
Obsutural, ohsuturalia. The placentarian partitions
applied only to the sutures, and not fastened between the
edges of the contiguous valves. Convolvulus.
Opposite, opposiliva, valvis contraria. The edges of the

applied to the middle of the valves.
Parallel, parallelica, valvis parallela. The placentarian
