Description

"Shrubs or perennial or annual herbs with stellate pubescence. Leaves unlobed to palmately lobed or dissected; petioles usually long; stipules present, usually caduceus flowers solitary in the upper leaf axils, or in terminal racemes; peduncles and pedicels present or the peduncle obsolete, often elongating in fruit. Involucral bracts 7-15, linear. Sepals 5, widely triangular to triangular-lanceolate, enlarged in fruit; petals oblanceolate to obovate, apex rounded; stamens usually numerous; stigmas 5, capitate, styles free near apex. Capsule 5-locular." [1]

"Perennial with spreading-ascending or, less frequently erect branches to 1m tall. Trichomes of stems, petioles, leaves and pedicels short, bristly, stellate, scabrous. Leaves palmately 3-5 cleft or lobed, 3-9 cm long, mostly wider than long, coarsely and irregularly serrate, truncate to cleft with an inverted broad, V-shaped sinus; petioles 2-10 cm long. Flowers in leafly-bracteate racemes, bracts less divided than the leaves or entire; peduncles obsolete or to 2 mm long; pedicels 5-12 mm long, elongated slightly in fruit, usually with a few long white trichomes; Involucral bracts 8-10, linear, 1-2 cm long, usually palmately or pinnately cleft at apex. Calyx lobes triangular-lanceolate, 8-12 mm long, acute, elongated in fruit, distinctly keeled to the apex and with a thickened margin resembling the keel, pubescent with long stiff, postulate-based trichomes; petals cream, turning a deeper yellow and finally fading to pink, crimson marked at base, 5-6 cm long. Capsule gradually contracted to a beak, 1.7-2 cm long, pubescent with mixed short and long, bristle-like trichomes. Seeds brown, with fine reticulations and with a few whitish papillate, 3.5-4 mm long." [1]

Distribution

Ecology

Habitat

Generally, Hibiscus aculeatus can be found in pine savannas and dry loamy or sandy soils found in maritime forests.[3] It is listed by the USDA Natural Resources Conservation Service as a facultative wetland species, where it most often can be found in wetland habitats but can also occasionally occur in non-wetland habitats.[2]

Phenology

H. aculeatus generally flowers from June until August, and fruits from July until September.[3] It has been observed to flower May to September with peak inflorescence in July.[4]
