초체 전체적으로 털은 없고 줄기가 분백색을 띤다 

 

 

주두는 5갈래

 

 

종소명 coccineus에서 보듯이 꽃색은 진홍색이나 아래 FNA 기재문에 보듯이 드물게 흰색이 있다 한다

 

 

부꽃받침(기재문에는 소총포로 되어 있다)은 선상피침형이고 꽃을 싸듯이 위로 굽어 있다.

개수는 9-15개로 되어 있는데 사진에서는 14개가 확인된다

Herbs, perennial, to 3(–3.5) m, herbage glabrous throughout. Stems glaucous. Leaves: stipules caducous, linear-subulate, 1–3 mm; petiole 1/3 to equaling blade; blade orbiculate to transversely elliptic, deeply palmately 3–5-lobed, 10–19 × 13–25 cm, base cordate, segments linear-lanceolate, margins remotely, unevenly serrate, apices acuminate, surfaces glabrous, nectary absent. Inflorescences solitary flowers in axils of distal leaves. Pedicels jointed distally, 3–14 cm, 1/3–1 3/4 petioles; involucellar bractlets 9–15, linear-subulate, 2.5–4 cm, not ciliate. Flowers showy, horizontal or ascending; calyx divided 3/4 length, rotate, 3.5–6 cm, larger in and longer than fruit, lobes narrowly triangular, apices acute to acuminate, nectaries absent; corolla rotate, petals not overlapping, bright red, narrowly spatulate-obovate, (6–)7.5–10 × 2.5–5.5 cm, minutely hairy abaxially where exposed in bud; staminal column straight, exserted, red, pink to white basally, 6.5–7 cm, bearing filaments in distal 1/3, free portion of filaments not secund, 4–8 mm; pollen dull yellow to dull red; styles red, 5–9 mm; stigmas red. Capsules brown, ovoid to globose, 2.8–3.5 cm, apex acute, apiculate, glabrous. Seeds brown, reniform-globose, 2.5–3.8 mm, hairy, hairs often in lines, brownish to reddish. 2n = 38.

 

Flowering late May–early Aug. Riparian and other freshwater marshes, ditches, swamps; 0–40 m; Ala., Ark., Fla., Ga., La., Miss., N.C., Tex., Va.

 

Except for the Florida records and two very old ones from Georgia, the distribution of Hibiscus coccineus given here is based on relatively recent reports and almost certainly represents escapes from cultivation rather than a natural distribution.

 

A rare, white-flowered form is known from southern Florida and is now in the horticultural trade. Petal color in Hibiscus coccineus has been shown to be under the control of a simple diallelic locus in which red is completely dominant over white (L. A. Gettys 2012).

 

In 1871, A. W. Chapman found plants of Hibiscus coccineus in eastern Florida that bore distinctive, shallowly-lobed leaves and his specimens form the basis for H. semilobatus. No extant populations of this variant have been rediscovered.
