Other factors grounding this assessment are the low number of known populations, the species habitat specificity and the fact that restinga areas suffer from strong instability and anthropogenic influence caused by tourism and urban expansion ( + +Rocha +et al. +2007 + +). Although the municipality where the +type +locality is included has a protected area (Área de Proteção Ambiental Piaçabuçu), none of the known populations are within its limits. Currently, only five collections are known for this new species. + + + + +Etymology: +—The epithet refers to the restinga vegetation, where the new species occurs. + + + + +Phenology: +—Collected with flowers and fruits in February to March, May and August, both during the rainy and dry seasons. + + + + + +Additional specimen examined ( +Paratypes +): + +— + +BRAZIL +. +Alagoas +: +Coruripe +, +Poxim +, + +18 August 2011 + +, + +E.C.O.

Surprisingly, in + +L. restingae + +, two different shapes of pericarp crystals occur together: rectangular and prismatic ( +Fig. 3 +). Both +types +were previously observed in other species of the genus by +Pruski (2017) +and + +Marques +et al. +(2018) + +, however, there were no reports of the +two types +being present in the same individual, thus reinforcing the novelty of this species. + + +Regarding its morphology, + +Lepidaploa restingae + +is easily recognized by the combination of oblong (rarely oblanceolate), subsessile leaves with long cuneate base, abaxial and adaxial leaf surfaces densely scurfy, flowering branches with yellowish setulose indumentum and the presence of yellowish glandular trichomes at the apices and bases of inner phyllaries. + + + +FIGURE 3 +. Raphide crystals in the pericarp of + +Lepidaploa restingae + +: prismatic (black arrows) and rectangular (red arrows). + + + +According to + +Marques +et al. +(2020) + +, among the 58 species of + +Lepidaploa + +occurring in +Brazil +, only + +L. mucronifolia +(Candolle 1836: 55) +Robinson (1990: 490) + +has occurrence recorded in the restingas of northeastern +Brazil +. That species is morphologically similar to + +L. restingae + +, especially due to its spirally-alternate leaves and laxly seriate-cymose capitulescence. However, + +L. mucronifolia + +has ovate leaves with rounded or cordate base and mucronate apex (vs. non mucronate) and 3–4-seriate involucre (vs. 4–5-seriate). + +Lepidaploa mucronifolia + +occurs in the states of +Bahia +, +Pernambuco +and +Sergipe +in areas of Caatinga ( +sensu stricto +) and restingas ( + +Marques +et al +. 2020 + +, Alves +et al +. in prep). In the states of +Alagoas +and +Sergipe +, these two species occur in sympatry in restinga areas. + + +The new species is also morphologically related to + +Lepidaploa araujoa +Robinson (1995: 391) + +. However, + +L. araujoa + +has linear leaves (vs. oblong, rarely oblanceolate) and sericeous abaxial leaf surface (vs. densely scurfy), congested capitulescence (vs. loose), and corolla lobes with T-shaped trichomes (vs. glandular, without tector trichomes). + +Lepidaploa araujoa + +is known only from its +type +collection, in restinga areas in the state of +Rio de Janeiro +, southeastern +Brazil +( +Robinson 1995 +, + +Marques +et al +. 2020 + +). However, the +type +of restinga where + +L. araujoa + +occurs, according to the classification by + +Villwock +et al. +(2005) + +, is part of the +East Coast +restingas, which are distinguished from other units due to climatic, geographical characteristics and sea currents. In addition, floristic studies have shown that +East Coast +restingas are a distinct vegetation +type +from the restinga communities of the Northeast ( + +Correia +et al +. 2020 + +). + + +The main morphological differences observed among the new species and its related taxa are shown in +Table 1 +. + + + + \ No newline at end of file
