Taxonomic notes

Subspecies: R. caroliniensis (J.F. Gmelin) Steudel ssp. ciliosa (Pursh) R.W. Long var. cinerascens (Fernald) Kartesz & Gandhi; R. caroliniensis ssp. ciliosa var. ciliosa

Varieties: R. ciliosa var. cinerascens Fernald; R. ciliosa var. typica

Description

"Perennial herbs. Leaves opposite, acute or obtuse, entire or undulate, base cuneate to attenuate, sessile or petiolate. Flowers in dense glomerules or in open cymes. Calyx tube short, lobes 5, elongate; corolla blue or rarely pink, funnel form, with tube, open throat, and 5 subequal lobes; stamens 4, included, anther locules parallel; stigmas 2-cleft. Capsules brown or yellow brown, compressed, ellipsoid-obovoid; seeds several, brown or gray."[2]

"Dwarf, pubescent perennial 0.5-1.5 dm tall, with a basal rosette. Leaves spatulate, obovate, or oblanceolate, to 7 cm long and 3 cm wide, pubescent, sessile or subsessile. Flowers in dense, sessile or subsessile, axillary glomerules. Calyx lobes hirsute, linear-setaceous, 15-30 mm long; corolla 3-4 cm long, tube longer than throat, lobes to 2 cm long. Capsules glabrous, 12-18 mm long, 5-6 mm broad; seeds gray, 3-4 mm long."[2]

Distribution

It is found in sandhills of Florida, Georgia, South Carolina, and North Carolina.[1]

Ecology

Habitat

In the Coastal Plain in Florida, it can be found in recently burned longleaf pine wiregrass woods, longleaf pine sandhills, burned longleaf pine ridges, open woodlands, turkey-oak-pinelands, scrub oak barrens, pine savannas, annually burned savannas and annually burned hardwoods.[3] It can also be found along roadsides, disturbed turkey oak-pinewoods, and pine-hardwood clearings. It grows in sandy loam and sandy soil. [3] Associated species include Sporobolus junceus, turkey oak and bluejack oaks.[3]

Phenology

This species has been observed to flower from May through September and in response to fire.[1][3][4] Kevin Robertson has observed this species flower within three months of burning KMR.

Fire ecology

It flowers within two months of burning in early summer (KMR). Ruellia ciliosa responds rapidly to fire and may be seen as one of the more common plants in longleaf pine native ground cover after a prescribed burn. Within a few weeks or so, Ruellia ciliosa, produces new leaves and flowers profusely but temporary[1](KMR). It was also observed to flower in areas raked and cleared of litter other vegetation in a longleaf pine-wiregrass site which otherwise had not burned for several years, suggesting that it germinates and flowers in response to to light (KMR).
