Herbaceous annual plant. Stem 0.4 ‒ 1 m tall, solid, slightly corrugated, covered with scattered multicellular trichomes ca. 1.5 mm long and scattered glands, which are denser on the upper part. Leaves opposite, not decreasing in size up to the stem or slightly so; lamina 7.5 ‒ 13.4 cm long, 3.4 ‒ 7.8 cm wide, ovate to broadly lanceolate, attenuate, truncate, dentate (teeth up to 1.5 mm), with very scattered multicellular trichomes and glands (the glands being denser beneath), pinnately veined; petiole 19 ‒ 60 mm long. Synflorescence corymbiform, with foliose bracts similar to the upper cauline leaves; capitula 5 ‒ 25, campanulate. Involucral bracts 27 ‒ 37, 3 ‒ 4-seriate, subequal; outer bracts 5.3 ‒ 6.5 mm long, 1.9 ‒ 2.9 mm wide, broadly lanceolate to ovate (rarely lanceolate), sclerified, covered with multicellular trichomes and glands; inner bracts 5.4 ‒ 5.8 mm long, 0.8 ‒ 1.6 mm wide, linear, paleaceous, with glands and multicellular trichomes on the upper part. Florets 190 ‒ 220, 2.5 ‒ 3.2 mm long, with glands along the whole surface and unicellular trichomes on the lobes; style base not enlarged with filiform or granular excrescences. Achenes 2.9 ‒ 3.7 mm long, (4)5-ribbed, with unicelular trichomes ca. 0.3 mm long on the ribs; pappus 0.9 ‒ 1.3 mm long, barbellate.

Distribution and Habitat: — Putative narrow endemic of southeastern Tocantins State ( Brazil). It grows within forests on well-watered limestone slopes.

Phenology: —Observed in bloom in April.

Discussion: —The isolectotype at HAL is misidentified as “ Campuloclinium hirsutum ” and the collector number should be Gardner 3816 instead of “3216”. Likewise, the duplicate K-000873831 shows the wrong collection date “1941”. These mistakes should be attributed to the labelling process or to the transcription of the new labels in the destination herbaria.

New collection: — BRAZIL. Tocantins: Arraias, Fazenda Sapé, 12º48 ′ 05 ′′ S 46º59 ′ 53 ′′ W, 475 m, J. Calvo 7521 & É. Ross-Nadié (ALCB, K, MA, MBM, RB, SPF, US).
