Taxonomic notes

Synonyms: Gratiola pilosa Michaux; Tragiola pilosa (Michaux) Small & Pennell[1]

Varieties: Tragiola pilosa (Michaux) Small & Pennell var. typica[1]


This description came from Gratiola pilosa in Radford (1964) and S. pilosa was listed as a synonym. "Leaves opposite, sessile, often obscurely to strongly glandular-punctate. Flowers solitary in the axils of leafy bracts, a pair of bractlets usually immediately below the calyx. Sepals 5, subequal; corolla small; the upper 2 stamens fertile, the lower 2 filaments rudimentary or absent, anther sacs usually transverse to flower axis, surpassed by expanded, membranous connective (or anthers normal in no. 1). Capsules ovoid to globose, glabrous."[2]

"Stiff, erect, usually unbranched perennials, 1-7 dm tall, the stem 1-2 mm in diam., pilose. Leaves ovate to ovate-lanceolate, 1.2-2 cm long, 5-11 mm wide; entire or irregularly serrate, pilose. Flowers sessile or subsessile, pedicels 1 mm or less long; sepals linear or linear-lanceolate, 3-7 mm long, subequal, pubescent, exceeded by the linear bractlets; corolla white or shaded with lavender, 6-8 mm long. Capsule conical, 4-5 mm long."[2]




This species usually grows in wet areas near the borders of swamps, bogs, ponds, and within floodplains.[3] S. pilosa has also been spotted in open scrub, moist pine barrens, pine flatwoods, live oak hammocks, and turkey oak-longleaf pine-blackjack oak woods.[3] It has been observed to grow in drying and moist loamy sands, sandy peat, and wet peat.[3] This species also occurs in human disturbed areas such as trails, planted slash pine woods near powerline corridors, roadsides, old pastures, swamp clearings, bog clearings, woodland clearings, flatwood clearings, disturbed cypress domes, and ditches.[3]

Associated species includes Pinus, Hypericum, Magnolia, Nyssa, Pinchkneya, Liquidambar, Quercus virginiana, Justicia, Calopogon, Habernaria, Eriocaulon, Carex, Quercus falcata, Pinus palustris, Pinus elliottii, Quercus nigra, Gordonia lasianthus, Cyrilla, Magnolia virginiana, and Quercus marilandica.[3]
