Conservation
According to available information about Piptolepis campestris, it can be scored, using IUCN conservation criteria (IUCN 2001), as Endangered (EN), since its area of occurrence is smaller than 5,000 km2, its area of occupancy is smaller than 500 km2, and it is known from no more than five localities EN (criteria B1a, B2a).
Distribution
Endemic to Minas Gerais and known only from the Diamantina region, Brazil.
Ecology
Campos rupestres, amongst rocks.
Morphology General Habit
Shrub or subshrub to 2 m
Morphology Leaves
Leaves alternate, simple, imbricate to subrosulate towards stems apices, patent to slightly ascending, shortly petiolate, petioles pad-like, 1.1 – 3 mm long; blade elliptic, more rarely narrow oblong to narrow obovate, 1.1 – 1.9 × 0.6 – 0.9 cm, densely velutinous to subsericeous, silverish canescent, black glandular dotted (sometimes scarcely visible) adaxially, densely velutinous to sericeous, silverish green abaxially, hairs simple, uniseriate, midrib prominent beneath, sunken above, venation brochidodromous, margins entire and smooth, apex obtuse to rounded, base rounded, sometimes slightly attenuate
Morphology Reproductive morphology Flowers Florets
Florets 19 – 21, hermaphrodite, fertile; corolla actinomorphic, 5-lobed, lilac, corolla tube 4.5 – 6.2 × 0.5 – 1 mm, glandular-punctate, corolla throat 1 – 2 × 0.5 – 0.8 mm, corolla lobes 2.4 – 3.2 × 0.4 – 0.6 mm, apices acute, mamillose; apical anther appendages acute, more than twice as long as wide, anther base long-sagittate; style 0.9 – 1.1 cm, style shaft glabrous throughout except for pubescent upper c. 0.8 mm beneath style arms, style base glabrous, lacking basal node, style arms 1.5 – 2.5 mm long, short pubescent outside throughout
Morphology Reproductive morphology Inflorescences
Inflorescence terminal, seldom axillary, a solitary capitulum or a simple, 2 – 5-headed pseudoglomerule, often surrounded by foliage leaves
Morphology Reproductive morphology Inflorescences Capitulum
Capitula homogamous, discoid, sessile; involucre cylindrical to campanulate, 7.3 – 13 × 3.8 – 7 mm; phyllaries 5 – 6-seriate, imbricate, outer phyllaries widely trullate to ovate, 2.4 – 4.9 × 0.7 – 1.7 mm, apex acute, tomentose to subvillous, greyish brown, inner phyllaries linear to lanceolate, 5.9 – 7 × 0.7 – 0.8 mm, apex acute to apiculate, glabrescent, greyish brown to stramineous, persistent or deciduous; receptacle flat, weakly fimbriate
Morphology Stem
Stems well-branched, slightly flattened, furrowed, pubescent to velutinous, canescent when young, becoming cylindrical, subglabrescent with ochreous remaining indument with age, leaf scars triangular, distinctive on leafless portions of stem
Note
Following Schultz-Bipontinus (1863), Piptolepis campestris belongs to sect. Macrophyllum Sch. Bip. It is similar to P. oleaster with its silverish canescent adaxial leaves and cluster of few heads, but is easily set apart from it by the shape of leaves (elliptic, more rarely narrow oblong to narrow obovate vs oblanceolate to linear-lanceolate) and number of florets per head (19 – 21 vs 15 – 16). It is also similar to P. schultziana, the other new species described below, by the shape and size of the leaves, but the adaxial surface is velutinous to subsericeous and silverish canescent (vs glabrescent, shiny and green). Geographically, P. campestris is restricted to the camposrupestres of the Planalto de Diamantina which is the centre of diversity of the genus (ten species occur in this region and eight are endemics). This species epithet denotes its habitat in open formations bound to a mosaic of rocky outcrops and shallow white sands above 1,000 m in Central and Eastern Brazil — the camposrupestres.
