학명: Melampodium sp.
분류: 국화과(Compositae)
* Melampodium은 전세계적으로 약 70여 종이 있다.
아래 것은 M. paludosum오 추정한다.
해바라기 종류에 비해 잎이 마주나는 것이 특징이다(해바라기 종류는 대개 어긋나기한다; 줄기 기부는 마주나기할 수도 있다)

국표식에는 아래 2종이 등록되어 있다
Melampodium leucanthum Torr. & A. Gray 멜람포디움 ; 설상화가 흰색
Melampodium paludosum Kunth 멜람포디움 : 설상화가 황색
그러나 FNA에는 Melampodium paludosum은 없고
Melampodium divaricatum (Richard) de Candolle 이 있는데
Yahoo에는 Melampodium paludosum Kunth이 Melampodium divaricatum (Richard) de Candolle 이 Synonym으로 처리되어 있는 곳이 많은데 일부에서는 두 종을 다른 종으로 보긷고 한다
높이는 60~100cm이다. 잎은 마주나고 달걀모양이며 잎자루가 없고 가장자리는 밋밋하여 털이 나서 거칠다.
끝이 뾰족하며 밑은 심장모양이다. 노란색 꽃이 6~10월에 피고 꽃줄기 끝에 1개씩 달린다. 총포조각은 둥글고 끝이 둔하며 윗 가장자리가 검은색이다. 열매는 수과로서 10월에 익는다, 종자로 번식한다.

[Often said (erroneously) to be from Greek melampodion, blackfoot; evidently traceable to Melampus, a soothsayer of renown in Greek mythology]

Annuals, perennials, or subshrubs, 5–50(–150+) cm. Stems erect or prostrate. Leaves cauline; opposite; petiolate (petioles usually winged) or sessile; blades deltate, lance-elliptic, lanceolate, lance-linear, linear, linear-oblong, ovate, or rhombic, sometimes pinnately lobed, ultimate margins entire or toothed, faces usually hairy, usually gland-dotted (at least abaxial). Heads radiate, borne singly (from forks of branches, peduncles often uncinate). Involucres mostly hemispheric (sometimes ± cupulate), [4–]5–20(–30+) mm diam. Phyllaries persistent (outer) or falling with cypselae, 8–20+ in 2 series (outer [2–]5 often ± connate, herbaceous, inner each investing a ray ovary, forming a perigynium, shed with enclosed cypsela). Receptacles flat or convex to conic (their tips, paleae, and spent florets often shed as a unit), paleate (paleae lanceolate to linear, scarious, conduplicate, often with dilated, erose tips). Ray florets [3–]5–13+, pistillate, fertile; corollas yellow, orange, or cream-white, sometimes purplish abaxially (tubes often wanting). Disc florets [3–]45–70[–100+], functionally staminate; corollas ochroleucous, yellow, or orange, tubes shorter than funnelform throats, lobes 5, ± deltate. Cypselae each enclosed within and shed with a smooth, sculpted, or tuberculate, scarious, coriaceous, or hardened perigynium (the ultimate "fruits" ± compressed, ± D-shaped); pappi 0. x = 12.
Species ca. 36 (7 in the flora): United States, Mexico, West Indies, Central America, South America; introduced in Old World.
