Description

"Herbs, whorled or alternate rarely opposite, entire leaves. Flowers lavender, pink, white or yellow, in racemes or spikes, terminating the branches or in terminal corymbs. Flowers perfect, zygomorphic, with 3 small sepals, frequently one of these slightly larger than the others, and 2 larger petaloid sepals (wigs). The 3 petals are united into a tube, 3-lobed at apex, the 2 lateral lobes usually the longer, the center lobe usually lacerate, often thicker in texture; stamens 6-8, united to the corolla tube in 2 rows. Capsule 2 –locular, with one seed in each locule. Seeds dark brown or black, ellipsoid or ovoid, rarely globose, 0.5-3 mm long, usually densely pubescent. The genus has been divided into several genera none of which have distinct characteristics. Orange flowers turn pale yellow on drying, yellow ones bluish green; the pink or lavender ones remain the same color or fade slightly." [1]

"Glabrous, glaucous annual. Stems strict to slightly branched, the cotyledons often present at flowering time. Leaves fleshy, alternate, linear, 5-17 mm long, setaceous or sharply acute. Flowers in spike or racemes; pedicels 1 mm or less long or absent. Sepals ca. 1 mm long, pink, acute or acuminate, wings similar but larger, 2.5-3 mm long, oblanceolate, pink; corolla tube reddish pink, prominently fringed, 5-6.5 mm long; stamens 8. Seeds black, 1-1.7 mm long; aril confined to base, lobe 1, scarcely projecting." [1]

Distribution

Ecology

Habitat

This species has been found in longleaf pine flatwoods, near sphagnum filled boggy areas, and savannas in drying and moist loamy sands of well drained uplands. [2] It has also been found in the sand pine scrub of Ocala National Forest.[3]P. incarnata has also been seen growing in disturbed habitats such as raked fire breaks of upland longleaf pine-wiregrass communities at Pebble Hill Plantation. [4] Associated species include longleaf pine and wiregrass. [2]

Phenology

P. incarnata has been observed flowering from April to July and in September with peak inflorescence in May.[2][5]

Fire ecology

It occurs in areas that are on frequent burn intervals. [2]
