    Involucre
    Involucre campanulate, 8 – 9 mm long, involucral bracts 3-seriate; external bracts 2.5 – 3.5 × 1.5 – 2 mm, ovate, densely hispid-glandulous, vinaceous, intermediate bracts 5 – 6.5 × 1.5 – 2 mm, oblanceolate, puberulous-glandulous, internal bracts 6.5 – 7.5 × 1.5 – 2 mm, lanceolate, puberulous-glandulous to glabrescent, vinaceous, both with a pointed ciliate apex, margins ciliate, internally fringed; receptacle plane, epaleaceous, honeycombed, glabrous
    Florets
    Florets 25 – 30, perfect, vinaceous corolla, tubulose, 6 – 7 mm long, glabrous, lobes discreetly papillose at the apex; anthers with oblong apex, obtuse base, cylindrical anther collar, slightly flattened; styles with clavate branches, bulbiformstylepodium, papillose

    Distribution
    Brazil, Minas Gerais, only in the municipality of Ouro Preto and the Parque Estadual do Itacolomi.
    Ecology
    In “campo rupestre” (rocky grasslands), in temporarily flooded area; 1500 m.
    Conservation
    According to the evaluation of the presently available information, this species can be scored, using IUCN Categories and Criteria (IUCN 2001), as Critically Endangered (CR Blabi,ii, B2abi,ii), since its Area of Occurrence is less than 100 km², its Area of Occupancy is less than 10 km², and it has been found only in one location.
    Note
    Eupatorium semiamplexifolium is characterised by semiamplexicaul leaves, a densely glandulous indumentum, with stalked glandular trichomes on the branches, leaves, bracts and cypselas; short-pedunculate capitula ordered in corymbs, pendulous, on the apex of divaricate branches, 3-seriate involucre with gradually larger bracts and flowers with papillose stylepodia. E. itacolumensis is the most closely related species, distinguished by the glabrous bracts, stalked capitula, 2-seriate involucre, with subequal bracts and flowers with glabrousstylepodia. E. semiamplexifolium belongs to sect. Heterolepis Baker series Subibricata DC. due to the presence of a involucre with 3 series of bracts, each gradually larger than the other. The specific epithet refers to the semiampliplexicaul foliar base.
