3. Lychnophora diamantinana Coile & Jones (1981: 532) . Type:— BRAZIL. Minas Gerais: 19 miles from Diamantina on route to Curvelo, 23 December 1959, B. Maguire et al. 44757 (holotype: NY [ NY01239471 ]; isotypes: GH e! [ GH00009905 ], K e! [ K001092364 ], RB [ RB00582286 , RB00591386 ], US [ US 00147438]) .

Distribution and habitat: — Brazil (Minas Gerais, endemic to the Diamantina Plateau). Campo rupestre; 950–1390 m.

Taxonomic Notes: —The main distinctive features are: lanceolate to falciform leaves with margins slightly revolute or not, acute apices, brochidodromous venation with fimbrial veins, winged and flattened midvein on the abaxial surface, spherical syncephalium of 5–12-flowered capitula. Lychnophora salicifolia is related to it, but easily distinguished from L. diamantinana by its leaves with scrobiculate adaxial surface, a mixed brochidodromous-eucamptodromous venation pattern and a prominent midvein enlarged basally on abaxial face; additionally, the outter pappus is coroniform (vs. free in L. diamantinana ). Also similar to L. pohlii : see that species for a discussion of the differences.
