Hojas opuestas, elípticas a ovadas o deltoide-ovadas, (1.5–) 2–12.5 cm de largo y 0.8–8 cm de ancho, ápice agudo a obtuso, base aguda, a menudo estrechándose gradualmente y formando una base subpeciolar, márgenes enteros a serrados o biserrados, ambas superficies seríceas con tricomas de 0.4–0.9 mm de largo, envés con glándulas sésiles; sésiles. Capitulescencias de capítulos solitarios en las hojas axilares y en las bifurcaciones del tallo; capítulos radiados; involucros hemisféricos, en 2 series, 4–5 mm de ancho; filarias exteriores 5–6, en 1 serie, libres, herbáceas, ovadas a lanceoladas, 3.2–5 mm de largo y 1.3–2 mm de ancho, ápice agudo, superficie abaxial pilosa con tricomas de hasta 1.2 mm de largo, márgenes ciliados con tricomas de hasta 1 mm de largo, filarias internas connadas con los aquenios del radio; receptáculos convexos a cónicos, paleáceos; páleas escariosas, conduplicadas, oblanceoladas, 1.3–1.6 mm de largo y 0.5–0.7 mm de ancho, con ápice subtruncado y lacerado-ciliado o lobado, glandulosas; flósculos del radio 5–9, pistilados, las lígulas elípticas, 1–1.5 mm de largo y 0.4–0.6 mm de ancho, amarillo pálidas, el tubo de 0.2 mm de largo; flósculos del disco (5–) 7–8, funcionalmente estaminados, con ovarios estériles y sin vilano, las corolas con garganta ampliamente infundibuliforme, 0.6–0.8 mm de largo, el tubo 0.5–0.7 mm de largo, amarillo; anteras 0.5–0.7 mm de largo. Aquenios con filarias internas adherentes, cuneados, 4–5 mm de largo y 2.4–3 mm de ancho (sin las espinas), fuertemente comprimidos, glandulosos, equinados en toda la superficie, los ángulos con espínulas rectas o uncinadas, las del ápice alargadas, (1.7–) 2.5–4.5 mm de largo; vilano ausente.

    Una maleza común en orillas de caminos, campos y áreas alteradas, zonas pacífica y norcentral; 0–1200 m; fl y fr jun–ene; Robleto 1099, Stevens 9903; Belice a Nicaragua, Sudamérica, las Antillas. Es similar a Acanthospermum humile (Sw.) DC., especie que difiere por tener las hojas con pecíolo más corto y las espínulas mayormente confinadas a los márgenes y al ápice de los frutos accesorios. Un género neotropical con 6 especies, similar a Melampodium pero este último carece de espínulas en las superficies del fruto accesorio.
