Family - Loganiaceae Stems - To +/-50cm tall, herbaceous, erect, glabrous, multiple from base, typically simple, minutely winged from decurrent leaf tissue. Wings to -1mm broad.
Leaves - Opposite, sessile, decussate, ovate, acuminate, entire, to +10cm long, +5cm broad, typically glabrous above, short sparse pubescent below (mostly on the veins). Inflorescence - Terminal one-sided (secund) spike to +/-10cm long.
Flowers - Corolla tube deep crimson externally (yellowish at very base), pale yellow to yellow internally, to +/-4cm long, 5-lobed. Lobes lanceolate, 1.2cm long, 4-5mm broad, acuminate, glabrous, erect to spreading. Stamens 5, alternating with the corolla lobes, adnate at apex of corolla tube, erect. Filaments 6-7mm long, white, glabrous. Anthers yellow, 3mm long. Style white, glabrous, 4cm long. Ovary superior, 2-locular, yellowish, 1.1mm long, 2mm broad, glabrous. Placentation axile. Sepals 5, attenuate, 7-8mm long, 1.1mm broad at base, glabrous.
Flowering - May - August. Habitat - Low moist woods, ravines, streambanks. Origin - Native to U.S. Other info. - This striking species can be found in a handful of southeastern counties in Missouri. The plant is easy to identify in the field because of its brilliant red flowers and opposite leaves. No other species resembles it while in flower. S. marilandica can be grown from seed and does well in cultivation if given moist conditions and partial shade. The plant contains alkaloids and calcium oxalate crystals and was used traditionally as a parasite remedy.

Family - Caryophyllaceae Stems - From a woody caudex, multiple from the base, herbaceous, erect, branching, fistulose, densely glandular pubescent, to 50cm tall.
Leaves - Leaves of basal rosette spatulate, petiolate, to +/-15cm long (with petiole), 2cm broad, acute, entire. Blades mostly glabrous. Margins ciliate, especially on petiole. Cauline leaves opposite, becoming sessile, lanceolate to lance-linear, entire, viscid glandular pubescent, acute, reduced upward, typically less than 8 pairs on a stem.
Inflorescence - Loose terminal bracteate cymes. Pedicels to -4cm long, densely glandular pubescent. Flowers - Petals 5, clawed. Limb crimson, 2cm long, 6mm broad, notched at apex, glabrous. Claw -2cm long, mostly scarious but reddish near apex, glabrous. Fornices 2, 3-4mm long, erect, red. Stamens 10, half adnate at base of petals, half not adnate to petals, exserted. Filaments 2.4cm long, glabrous, greenish-white below, reddish near apex. Anthers 3mm long, 2-lobed, greyish-green. Ovary on small gynophore(to 1.5mm long), cylindric, yellow-green, 6mm long, -2mm in diameter. Placentation free-central. Ovules many. Styles 3, white below, red above, -2cm long. Calyx tube to 1.7cm long, 5-lobed, densely glandular pubescent, often with a reddish tinge, 10-nerved, glabrous internally. Lobes acute, triangular, 4mm long.
Flowering - April - June. Habitat - Rocky woods, ledges, wooded slopes. Origin - Native to U.S. Other info. - This showy species can be found in the Ozark section of Missouri. This plant and the closely related S. regia Sims have some of the most brilliant red flowers in nature. Both of these species flower at the same time and can be difficult to distinguish from one another. S. regia differs from S. virginica in having many more pairs of leaves on its stem and by having petals which are not notched at the apex. Both plants are worthy of cultivation and grow well from seed.

Appendages subulate, acute, erect, red, +/-5mm long, -2mm broad. Stamens 10, 5 adnate to the base of the petals and 5 alternating with the petals, slightly exserted. Filaments white but darkened near the apex, +2.5cm long, glabrous. Anthers +/-2mm long, greenish-blue. Styles 3, distinct, well exserted, to +3cm long, glabrous, white with purple apices (stigmas). Ovary superior, green, glabrous, cylindric, 7-8mm long, 2mm in diameter (in flower), unilocular. Placentation free-central. Ovules many. Calyx tubular, green, densely viscid glandular externally, glabrous internally, 10-ribbed, accrescent, +/-2.5cm long, truncate and slightly saccate at the base.

Origin - Native to the U.S. Other info. - This striking plant can be found in the Ozark region of Missouri but is sometimes cultivated elsewhere. This species is easy to identify in the field because of its brilliant flowers and stems which have many nodes and leaves. Another species, S. virginica L., is similar but is a smaller plant with mostly basal leaves. Both species rival any commonly cultivated plant and should be grown more in home gardens.
