Used with permission from ©: Conservatoire et Jardin Botaniques de la Ville de Genève. + + + + +Distribution and habitat +:—Species cited by +Webster (2002) +for +Argentina +and +Brazil +(MG, SC, SP and RJ). However, the analysis of the collections mentioned by the author revealed that those mentioned for +Argentina +, and for the states of +São Paulo +, +Santa Catarina +and +Rio de Janeiro +, in +Brazil +, correspond to + +P. niruri + +. In this way, we restricted the distribution of + +P. rosellus + +to the state of +Minas Gerais +, southeastern +Brazil +( +Fig. 4 +). It lives in “cerrados típicos” “campos limpos” e “Campos Rupestres” e “florestas estacionais”, in addition to transition areas of Cerrado and Atlantic Forest, on sandy soils or on rocky outcrops between 840 and 2000 meters of elevation. + + + + +Preliminary conservation status +:— + +Phyllanthus rosellus + +is being categorized as Least Concern (LC), criterion B1, for presenting an Extent of Occurrence (EOO) estimated at +79,232.597 km +2 +. Additionally, more than 30 populations of the species are known, some of which were found in protected areas, such as: Serra do Intendente State Park (Delfinópolis), APA Estadual Cachoeira das Andorinhas (Ouro Preto) and Serra Canastra Park National (São Roque de Minas), the which ensures, in a certain way, its conservation. Despite this, it grows in Atlantic Forest and Cerrado Biomes, which are considered the most degraded by extensive livestock farming, mining and intense deforestation for agropastoral activities ( + +Ribeiro +et al +. 2009 + +, + +Myers +et al. +2000 + +, + +Mittermeier +et al. +2004 + +). + + + + +Notes +:— +Müller Argoviensis (1863) +established + +P. lathyroides +f. +rosellus + +based on tiny leaves, solitary flowers with a strong pink color and pedicels +4–6 mm +long. Ten years later, +Müller Argoviensis (1873) +elevated it to species level based on short branches ( +7–15 cm +long) and unisexual, tiny leaves ( +3–4 mm +long), large stipules ( +2–3 mm +long), long pedicels of flowers of both sexes ( +4–6 mm +), and solitary flowers with a strong pink color. +Kuntze (1891) +, using the principle of priority, transferred the species of + +Phyllanthus + +known at the time to the genus + +Diasperus + +. However, this decision was not accepted, since the International Code of Botanical Nomenclature adopted the genus category from the date of publication of Species Plantarum (1753), where the genus + +Phyllanthus + +was described. + + + +FIGURE 4. +Distribution of + +Phyllanthus rosellus + +in Brazil.

Despite this, +Webster (2002) +, in agreement with +Müller Argoviensis (1873) +, treated + +P. rosellus + +as a distinct species from + +P. niruri + +, arguing that the species differed from + +P. niruri + +by its tiny leaves, strongly pink solitary flowers and larger pedicels ( +4–5 mm +length), but highlighting that specimens of + +P. niruri + +with tiny leaves are difficult to separate from + +P. rosellus + +. In contrast, + +Martins +et al. +(2014) + +, in agreement with +Allem (1977) +, reduced + +P. rosellus + +to a synonym of + +P. niruri + +, arguing that the size of the leaves and floral structures, as well as the color of the sepals, are variations present in + +P. niruri + +. + + +During the analysis of the +type +collections, protologues and field collections, it was observed that some qualitative characteristics cited for the reinstatement of + +P. rosellus + +, for example, size of stipules and pedicel, in addition to solitary flowers vary between populations. However, we assume that the specimens from the state of +Minas Gerais +are clearly distinguishable from + +P. niruri + +, due to their unisexual branches, cataphylls with strongly serrate margins, tiny leaves ( +2.2–3.5 mm +long), staminate flowers distributed along the branchlets and flowers of both sexes with a strongly pink color, which is why we consider + +P. rosellus + +distinct from + +P. niruri + +( +Table 1 +). + + + +TABLE 1 +.

+ + +Although the distribution of + +P. rosellus + +is restricted to the state of Minas Gerais, it does not occur sympatrically with + +P. niruri + +. + +P. niruri + +according to +Webster (1955 +, +2002 +) is distributed from +United States +to +Argentina +, including West Indies, and has been introduced or naturalized in countries in Europe and Africa ( + +Bouman +et al. +2022 + +). In +Brazil +it occurs from north to south, in all phytogeographical domains ( +Silva & Sales 2007 +, + +Torres +et al. +2022b + +). Although + +P. niruri + +is a very variable species in the size of the leaves ( +5.5–9.2 mm +long), the shape of the sepals of both flowers (the staminate obovate or suborbicular, the pistillate elliptical, obovate or combinations), fusion of the stamens (joined up to half the filaments or completely free) color of the sepals (whitish, greenish or slightly pink), can be recognized and differentiated from the others of + +Phyllanthus +subsect. +Phyllanthus + +, by the association of bisexual branchlets, distributed along the main stem or its ends, staminate and pistillate flowers with pedicels +2–4 mm +long, and +3–5 mm +long, respectively, capitate stigmas and verruculose seeds. + + +According to the circumscription of +Webster (1955 +, +2002 +) and + +Bouman +et al. +(2022) + + +Phyllanthus +sect. +Phyllanthus +subsect. +Phyllanthus + +includes seven species. Subsequently, +Torres & Silva (2022 +, +2023a +, b, c) established five new species for this subsection and proposed the synonymization of + +P. bolivianus +Pax & K.
