regular, placed opposite each other in pairs, their spreading limbs
forming a cross. Stamens 6, two of them inserted lower down and shorter
(rarely only 4 or 2). Pod usually 2-celled by a thin partition stretched
between the two marginal placentae, from which when ripe the valves
separate, either much longer than broad (a _silique_), or short (a
_silicle_), sometimes indehiscent and nut-like (_nucumentaceous_), or
separating across into 1-seeded joints (_lomentaceous_). Seeds
campylotropous, without albumen, filled by the large embryo, which is
curved or folded in various ways: i.e. the _cotyledons accumbent_, viz.,
their margins on one side applied to the radicle, so that the
cross-section of the seed appears thus o==; or else _incumbent_, viz.,
the back of one cotyledon applied to the radicle, thus o||. In these
cases the cotyledons are plane; but they may be folded upon themselves
and round the radicle, as in Mustard, where they are _conduplicate_,
thus o>>. In Leavenworthia alone the whole embryo is straight.--Leaves
alternate, no stipules. Flowers in terminal racemes or corymbs; pedicels
rarely bracted.--A large and very natural family, of pungent or acrid,
