side touch a placentarium, or some other partition ; so that 
each partition, taken separately, does not divide the hollow 
of the pericarp into two cells. Syringa vulgaris, Citrus, 
Nigel la Hispanica. 
Complete, completa. Dividing the cavity of the peri- 
carp completely, by being either a general partition itself, 
Cheiranthus, or if partial, by touching some other par- 
tition. 
Incomplete, incompleta. Only dividing the cavity in- 
completely, being partial partitions that do not touch one 
another, nor abut upon a placentarium. Fapaver. 
Valvean, valve ana. Formed by the expansion of the 
substance of the valves, and remaining fixed to them, when 
the pericarpium splits open. 
Median, mediana , medivalves , valvis contraria , valvis me- 
dio septiferis. Valvean and arising from the middle of the 
valves^ Liliurh, Syringa, Acanthacem, Polemonium, Hen- 
an them um. 
Marginal, marginalia , valvis utroque margins inlroflexo 
singulis loculum constitutentibiis P valvar es. Valvean, and 
formed by the edge of the valves, which turns into the 
interior of the pericarp, towards a real or imaginary cen- 
tral axis.. Antirrhinum, Rhododendrum, Astragalus. 
Two-flaked, bilame Hares. Marginal, anti formed by the 
union of the edges of two contiguous turned-in valves, 
which separate when the fruit opens. Digitalis, Rhodo- 
dendrum. 
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. Plantagineae^ Cruciferse, Tunica 
Granatum, Cucurbitaceae. 
Interposed, inter positive^ valvis margine appositis 'anguUs 
dissepimenti. Several placentarian partitions diverging 
from the centre of a many-valved pericarpium to the su- 
tures, so that they alternate with the valves. Convolvu- 
laceae. 
Obsutural, obsuturalia. The placentarian partitions 
applied only to the sutures, and not fastened between the 
edges of the contiguous valves. Convolvulus. 
Opposite, oppositiva , valvis contraria . The edges of the 
placentarian partitions applied to the middle of the valves. 
Paullinia pinnata. 
Parallel, parallelica , valvis parallela . The placentarian 
partition expanded parallel to the valves of a bivalve peri- 
o 2
