spicate

Aquatic or marsh herbs; flowers perfect or polygamo-diœcious, small, axillary or spicate; petals often none.

Spiraea.—Vigorous growing plants of great beauty, preferring good, deep, rather moist soil; the flowers small but very abundant, in large corymbose or spicate panicles.

The yellow flowers are produced on spicate racemes, while the leaves are alternate, smooth and spear-shaped.

The spikelets are all unisexual, spicate, the male and female spikelets are dissimilar, and are on the same or on different spikes.

Under this head, too, may be included those cases wherein an ordinarily spicate inflorescence becomes paniculate owing to the branching of the axis and the formation of an unwonted number of secondary buds.
