raceme

The flowers are very small, almost sessile, and arranged in a one-sided, curved raceme.

Its rather large crimson flowers are on very short stalks in the axils of the upper leaves, forming together a leafy raceme.

The flowering stems each bear a dense cluster of dull pink or purple heads, forming a raceme from four inches to a foot in height.

Its stem is erect, without runners; and the blue flowers form a one-sided raceme without bracts.

The flowers are perfect, reddish green, in distant whorls, forming a terminal raceme which is leafless above.
