XVI. Piptolepis Schultz-Bipontinus (1863: 380) , nom. cons., non Piptolepis Bentham (1840: 29) [ Oleaceae ], nom. rej. Type:— Piptolepis ericoides Schultz-Bipontinus (1863: 384) .

( Fig. 34 A , 35 , 36 )

Shrubs, subshrubs or treelets; stems well branched. Indumentum tomentose to velutinous, composed of 3- to 5-armed swollen, sometimes not swollen, unbranched auriculate trichomes, seldom stellate swollen trichomes. Leaves alternate, sessile to petiolate, with a pad-like or rarely semi-amplexicaul sheath, blade coriaceous, discolorous, seldom ericoid, margin entire, flat or revolute, venation brochidodromous or frequently hyphodromous. Inflorescence a terminal, sessile or rarely pedunculate, solitary capitulum or pseudoglomerule of capitula, rarely a syncephalium (second-order) ( P. pabstii ). Capitulum sessile or seldom pedunculate. Involucre cylindrical or campanulate; phyllaries (3–)5–6-seriate, weakly imbricate, caducous, pubescent; receptacle areolate, rarely fimbrillate or naked. Florets (1–)9–29; corolla purple, tube longer than limb; corolla lobes pubescent or glabrous; anthers calcarate; style lacking basal node. Cypsela cylindrical, rarely prismatic or turbinate, glabrous or rarely pubescent ( P. pabstii ); carpopodium inconspicuous; pappus biseriate, deciduous or caducous, rarely persistent, whitish to stramineous, rarely reddish, setae bases wider, outer series shorter than inner series or subequal, setose to paleaceous, inner series straight or seldom twisted, subpaleaceous to paleaceous, rarely setose. Chromosome number: unknown.

Taxonomic notes: —A genus of twelve species, eleven occurring in campos rupestres of the Espinhaço Range of mountains (Minas Gerais), one ( Piptolepis pabstii ) in the Serra dos Cristais (Goiás). The monophyly of Piptolepis is supported by molecular and morphological data ( Loeuille et al. 2015b) and the genus is characterized by the combination of pad-like leaf sheath (rarely a semi-amplexicaul leaf sheath), 3- to 5-armed swollen trichomes, weakly imbricate caducous phyllaries and outer pappus seta with a wider base.
