    Flowers
    Glomerulescence a cyme of 2 – 4 glomerules
    Capitulum

    Distribution
    South America: endemic to Minas Gerais State, Brazil (Map 2).
    Ecology
    In camposrupestres, among rocks.
    Conservation
    According to available information about Eremanthusbrevifolius, it can be scored using IUCN conservation criteria (IUCN 2001) as Vulnerable (VU), since its area of occupancy is very restricted VU (criteria D2). The single locality known is outside of a protected area and thus, prone to the effects of human activities.
    Note
    Preliminary data from the molecular phylogeny has conflicted with the infrageneric classification proposed by MacLeish (1987), thus Eremanthusbrevifolius is not being assigned to any infrageneric categories at this time. It is related to E. hatschbachii H. Rob., by the small size of its leaves and a biseriate pappus without an outer reduced series, but this new species differs by the leaf shape (narrowly oblong to elliptic, rarely oblanceolate or lanceolate vs ovate), the indument of the adaxial face (densely black glandular dotted, tomentose vs glabrous) and the number of florets (4 – 7 vs 2 – 3). E. brevifolius is also similar superficially to E. elaeagnus in habit, indumentum of abaxial leaves and capitula sessile slightly appressed and free, but differs in leaf size (2 – 2.5 × 0.6 – 0.8 cm vs 5 – 12 × 1.5 – 3 cm), the indumentum of the adaxial surface (densely black glandular dotted, tomentose vs sparsely lepidote), the number of florets per capitulum (4 – 7 vs 3 – 4) and the number of series of pappus setae (2 vs 3 – 5).

    In terms of distribution, Eremanthushatschbachii is presently known only from Serra do Cabeludo (Mun. Mucugê) in the state of Bahia, while E. elaeagnus is a common species in Minas Gerais especially in the Espinhaçomoutain range as well as in Serra da Canastra. E. brevifolius is currently known only from the type collection in Serra Talhada, a northeastern extension of Serra do Cipó, a region well known for its many endemics in the Compositae. Two other species of Eremanthus (E. elaeagnus and E. erythropappus) have been recorded, so far, in Serra Talhada. E. brevifolius is probably a microendemic to this region, a distribution pattern common in the Lychnophorinae. The type locality has been very poorly collected until now which probably explains why we have found only a single collection even after visiting most of the Brazilian herbaria. Even if it might be considered challenging to describe a new species based on a single collection, such characteristics as the number of series of pappus setae and of florets per capitulum clearly prevent us from considering it conspecific with E. elaeagnus.
