Conservation
According to available information about Piptolepis monticola, it can be scored using IUCN conservation criteria (IUCN 2001) as Critically Endangered (CR), since its area of occurrence is smaller than 100 km2, its area of occupancy is smaller than 10 km2, and it is known from only one locality CR (criteria B1a, B2a).
Distribution
Endemic to Minas Gerais and known only from Pico do Itambé, Brazil (see Notes).
Ecology
Campos rupestres, amongst rocks.
Morphology General Habit
Shrub or treelet to 2 m
Morphology Leaves
Leaves alternate, simple, slightly imbricate, subsessile to short-petiolate, pad-like petioles 2.5 – 6 mm long; blade oblanceolate, linear-obovate to spatulate, 1.5 – 2.5 × 0.5 – 1 cm, pubescent to sericeous, glaucous, canescent, black glandular dotted (sometimes scarcely visible) above, tomentose, glaucous, light grey beneath, midrib prominent beneath, sunken above, venation brochidodromous, margins entire, apex acute to obtuse, base cuneate
Morphology Reproductive morphology Flowers Florets
Florets 15 – 18, hermaphrodite, fertile; corolla actinomorphic, 5-lobed, lilac to magenta, corolla tube 5.3 – 6.5 × 0.3 – 0.5 mm, glandular-punctate, corolla throat 2 – 3 × 0.7 – 1 mm, glandular-punctate, corolla lobes 2.9 – 3.4 × 0.3 – 0.5 mm, apices acute, sparsely pilose; apical anther appendages lanceolate, more than twice as long as wide, anther base long-sagittate; style 0.7 – 1.3 cm, style shaft glabrous throughout except for pubescent upper c. 1.5 mm beneath style arms, style base glabrous, lacking basal node, style arms 1.3 – 2 mm long, short pubescent outside throughout
Morphology Reproductive morphology Inflorescences
Inflorescence terminal, a simple, 3 – 4-headed pseudoglomerule, often surrounded by foliage leaves
Morphology Reproductive morphology Inflorescences Capitulum
Capitula homogamous, discoid, sessile; involucre cylindrical to subcampanulate, 6.5 – 8 × 5.2 – 6.5 mm; phyllaries 5 – 6-seriate, weakly imbricate, outer phyllaries, triangular to widely trullate, 2.7 – 6.7 × 1.1 – 1.6 mm, apex acute, tomentose, stramineous to greyish, inner phyllaries linear to lanceolate, 7.1 – 8.2 × 1 – 1.4 mm, apex obtuse to acute, glabrescent or tomentose towards apices, deciduous; receptacle flat, weakly fimbriate
Morphology Stem
Stems well-branched, furrowed, glaucescent, canescent tomentose, dark greyish with age, leaf scars triangular
Note
Piptolepis monticola differs from P. buxoides by its larger leaves (1.5 – 2.5 × 0.5 – 1 cm vs 1 – 1.6 × 0.3 – 0.4 cm ), 3 – 4-headed pseudoglomerule (vs a solitary capitulum) and higher number of florets per capitulum (15 – 18 vs 12 – 13). It is closely related to P. oleaster by the number of capitula per inflorescence and by the number of florets per capitulum, but the latter species has leaves longer (1.5 – 2.5 cm vs 2 – 5 cm) and distinctly petiolate (vs subsessile to shortly petiolate). The new species is also similar to P. gardneri, but the leaves of the latter are linear-elliptic to linear-oblong (vs oblanceolate, linear-obovate to spatulate) and not glaucous (vs glaucous). Most available collections of P. monticola come from Pico do Itambé, while the label of the Martius’s collection indicates “Itambé do Mato Dentro”, another locality in Minas Gerais. Nevertheless, it seems more likely that there has been some confusion with these similar names than there having been a wider distribution of the species at the time of Martius’s collection now restricted to the Pico do Itambé. The species epithet derives from the name Albertiniamonticola Mart., in sched., which appears on the label of the oldest collection.
