Herbs, perennial, to 2.5 m. Stems glabrous or variously hairy, but without line of curved hairs. Leaves: stipules subulate, 1–4 mm; petiole 1/4–3/4 blade, glabrate or finely hairy; blade narrowly to broadly lanceolate to triangular-ovate or orbiculate, 3-lobed or unlobed, 8–20 × 3–13 cm, base cordate to cuneate, margins crenate to dentate or serrate, apex acute to acuminate, surfaces variously hairy, sometimes glabrous adaxially, nectary absent.

Flowers ± horizontal to slightly declinate; calyx divided 1/2–2/3 length, broadly campanulate, 1.5–4 cm, somewhat larger in fruit, lobes triangular or triangular-ovate, apices acute to subcaudate, surfaces hairy, nectaries absent; corolla funnelform to broadly so, petals pink or white, sometimes with red spot basally, narrowly to broadly, obliquely obovate, 4–12 × 3.5–6.5 cm, margins repand, sometimes undulate, minutely hairy abaxially mostly where exposed in bud; staminal column straight, white or cream, 1.2–5 cm, to 1/2 as long as petals, bearing filaments nearly throughout, free portion of filaments not secund, 2–8 mm; pollen yellow; styles white, 10–40 mm; stigmas creamy white to yellow. Capsules dark brown, ovoid to subglobose, 1.4–3.5 cm, apex apiculate, glabrous or hairy. Seeds brown, reniform-globose, 2.5–3 mm, verrucose-papillose. 2n = 38.

Hibiscus moscheutos Linnaeus subsp. moscheutos

[E]

(학명 이명)

Hibiscus incanus J. C. Wendland; H. moscheutos subsp. incanus (J. C. Wendland) H. E. Ahles; H. moscheutos subsp. palustris (Linnaeus) R. T. Clausen; H. oculiroseus Britton; H. palustris Linnaeus

(설명)

Flowering mid Jun–Aug. Brackish and freshwater marshes, floodplain pools, beaver ponds, roadside ditches, farm ponds; 0–400 m; ont.; Ala., Conn., Del., D.C., Fla., Ga., Ind., Kans., Ky., La., Md., Mass., Mich., Miss., N.H., N.J., N.Y., N.C., Ohio, Okla., Pa., R.I., S.C., Tenn., Tex., Va., W.Va., Wis.; introduced in Europe (sw France, n Italy, nw Portugal); Asia (Georgia).

Hibiscus incanus usually has been treated as having hairy capsules (for example, D. M. Bates 1965; G. E. Crow and C. B. Hellquist 2000; R. K. Godfrey and J. W. Wooten 1981; B. P. G. Hochreutiner 1900; T. H. Kearney 1955b; J. K. Small 1933), which places it with subsp. lasiocarpos; the original description by Wendland and later illustration of H. incanus show that it lacks hairs and belongs here (O. J. Blanchard 2008).

Subspecies moscheutos is widespread and variable in eastern North America. In the northeastern part of its range, it corresponds to Hibiscus palustris, synonymized here. That form also extends westward across the ontario and Erie plains to the vicinity of the south end of Lake Michigan. Distinctly different plants that agree with H. moscheutos in the narrow sense occur in southern Indiana and Ohio and southward. Along the eastern seaboard, where Hibiscus occupies the coastal marshes of nearly every county from New Hampshire to northeastern Florida, the distinction between the two taxa breaks down. General north-to-south clinal variation occurs, with local exceptions, in features that in the Midwest readily separate the two, including leaf width, leaf lobing, capsule shape and size, and frequency of adnation of petiole and pedicel. Petal color in these strikingly large-flowered plants is mostly pink throughout in the north, and white with a red base in the south; in Maryland and Delaware, there are populations in which all four possible color combinations occur (O. J. Blanchard 1976). Moscheutos-like flowers with white petals and red bases occur in New York, and pink-petaled flowers are found in North Carolina. These and similar observations by others have led to reducing the two to subspecific rank (R. T. Clausen 1949b) or fully merging them, as has been done in most recent floras; M. L. Fernald (1942c) made a case for maintaining them as separate species. See Blanchard for further discussion.

Shinnecock Indians used subsp. moscheutos as a urinary aid (D. E. Moerman 1998).

Hibiscus lasiocarpos Cavanilles, Diss. 3: 159, plate 70, fig. 1. 1787; H. californicus Kellogg; H. lasiocarpos var. occidentalis (Torrey) A. Gray; H. leucophyllus Shiller; H. moscheutos var. lasiocarpos (Cavanilles) B. L. Turner; H. moscheutos var. occidentalis Torrey

(설명)

Leaf blades lanceolate to broadly triangular-ovate, seldom lobed, usually hairy adaxially. Involucellar bractlets 1.5–4.5(–5) cm, usually ciliate. Petals usually white, sometimes pink, with red spot basally. Capsules hairy. 2n = 38.

Flowering mid Jun–Aug. Freshwater marshes, edges of ponds and streams, roadside ditches, farm ponds; 0–400 m; Ala., Ark., Calif., Fla., Ill., Ind., Kans., Ky., La., Miss., Mo., N.Mex., Okla., Tenn., Tex.; Mexico (Chihuahua).

Subspecies lasiocarpos has been reported also from Utah; the relevant specimen at BRY was cultivated, grown from seeds sent from Hawaii (S. L. Welsh, pers. comm.).

Some authors have commented recently on the distinctness of subsp. lasiocarpos (O. J. Blanchard 2008; B. L. Turner 2008; S. R. Hill 2009). The first two are in agreement that H. lasiocarpos should be recognized at infraspecific rank; Hill has maintained it as a separate species and, at the same time, has recognized the California populations as H. lasiocarpos var. occidentalis.

R. L. Small (2004) used chloroplast and nuclear DNA sequences to construct a phylogeny of Hibiscus sect. Muenchhusia, which consists of H. moscheutos and the next four species of the present treatment. He found support for the distinctness of the latter four, but four other analyzed taxa (H. incanus, H. lasiocarpos, H. moscheutos, and H. palustris), all of which together comprise H. moscheutos in the broad sense used here, produced a distinct but mostly unresolved clade. This evidence favors the view that H. lasiocarpos is better treated at infraspecific rank.

S. R. Hill (2009, 2012) has made a case for maintaining the California populations as a distinct variety. The morphological and phenological features of the variety, including its often orbiculate leaves, presence of rhizomes resulting in vegetative propagation, and conspicuous beaked flower buds have in the past supported its treatment as a distinct species, H. californicus. In the context of the present treatment, this taxon would be called H. moscheutos var. occidentalis Torrey.
