Description

"Perennial herbs with quadrangular, erect to ascending stems; stolons absent, or present and underground. Leaves sessile or petiolate. Racemes bracteate, often paniculate. Calyx zygomorphic, 2-lobed, the upper lobe crested, very small in flower and enlarging in fruit; corolla zygomorphic , upper lip galeate, 3-lobed, lower lip unlobed, usually white in the throat. The blue-flowered species occasionally have white flowered forms. Stamens 4, exserted; stigma 2-parted. Mericarps dark brown to black, closely set with tubercles or papillae in somewhat concentric rings, rounded, often somewhat flattened."[1]

"Plant not stoloniferous, forming clumps of 1-3, rarely more, stems. Stems erect, 1.5-8 dm tall, simple or branched above, pubescent, with 3-5 pairs of leaves below branches or inflorescence. Leaves elliptic to rhombic-ovate, 3-8 cm long, 1.5-4 cm wide, acute to obtuse, crenate, base cuneate to truncate; petioles usually obscured by decurrent blade tissue. Racemes 1-5, rarely more, 3-8 cm long; bracts reduced upward. Calyx 2-3 mm long in flower, 6-8 mm in fruit; corolla blue to violet, rarely white, 1.2-2 cm long. Mericarps tuberculate, 1.5-1.7 mm long."[1]

Distribution

Ecology

Habitat

In the Coastal Plain in Florida, S. elliptica can occur in upland pines.[2] Associated species include pines, sweetgum and dogwood.[2] S. elliptica responds negatively to agricultural-based soil disturbance in South Carolina coastal plain communities. This marks it as a possible indicator species for remnant woodland.[3]
