A weak, hairy herb, about a foot high, with alternate, oblong, entire, bicuspid leaves. The flowers are small, and disposed in terminal racemes, usually in pairs, which unroll as the flowers expand. The calyx is 5-lobed, and the corollas funnel-shaped, with a red tube about the length of the calyx-lobes, and a blue, 5-parted limb. The fruit consists of 4 distinct nutlets, which are contracted, and not hollowed, at the base. |
