            </p>
            <p> Mimosa amolariensis can be differentiated from  M. aguapeia Barneby by the poorly developed venation (versus robust venation), non-anastomosing secondary veins (versus anastomosing secondary veins), and truncate calyx lobes (versus triangular calyx lobes). </p>
            <p>Subshrub or erect shrub, 1–2 m tall. Subshrub or erect shrub, 1–2 m tall.

            <p> Taxonomic notes —We considered that  M. amolariensis as belonging to the ser.  Piresianae sensu Borges et al. (2022), since the presence of efoliate panicles and racemes, filiform setae in the pedicel, calyx paleaceous-pappiform, corolla funnelform-like (trumpet-shaped). In addition, the phylogenetic position of this species coincides with the placement in the ser.  Piresianae . It was detected by the inclusion of a distinctly identified sample in recent phylogenetic analyses (Borges et al. 2022). The representatives of this series have leaflets more than 10 mm wide (  M. kulhmannii ,  M. macropogon ,  M. piresii and  M. suberosa ) or leaflets less than 10 mm wide (  M. aguapeia ,  M. amolariensis ,  M. dasilvae ,  M. huanchacae ,  M. orbignyana and  M. riedelii ). Among the species with leaflets up to 10 mm wide,  M. amolariensis stands out by glandular trichomes in petiole and craspedia (in contrast to petiole and craspedia without glandular trichomes in  M. dasilvae ,  M. huanchacae and  M. riedelii ), the largest penultimate leaflet more than 12 mm length and the excentric veins divide the blade in 1:1:2 (opposite to  M. orbignyana in which the largest penultimate leaflet up to 12 mm length and the central vein divide the blade in 1:2), the secondary veins not anastomosed and the lobes of calyx truncated (unlike the secondary veins anastomosed and the lobes of calyx triangular in  M. aguapeia ). </p>
            <p> Distribution and habitat —To date,  Mimosa amolariensis has four known populations in the Serra do Amolar (Mato Grosso do Sul) and Serra de Santa Bárbara (Mato Grosso), in rocky outcrops of Campo Rupestre and Cerrado Rupestre at altitudes of 496–920 m asl. In hills of Serra do Amolar,  M. amolariensis occurs in higher altitude areas, where the vegetation consists of grasses (different  Poaceae species),  Vellozia variabilis Mart. ex Schult. &amp; Schult.f. , and  Mimosa xanthocentra Mart. var. xanthocentra also occur, as well as scattered woody species such as  Diptychandra aurantiaca Tul. ,  Kielmeyera rubriflora Cambess. ,  Miconia ferruginata DC. ,  Styrax ferrugineus Nees &amp; Mart. , and  Zeyheria montana Mart. In the restricted population at Morro Alegre hill (Serra do Amolar), we found six individuals in dried stream, between rocky outcrops, behind the top of the hill (Fig. 3). </p>
            <p>Phenology —Flowering and fruiting occur between March and July and individuals having only fruits were recorded until September. Some morphological traits, such as dehiscent articles, suggest that autochory is the main syndrome related to fruit dispersal. We did not detect morphological traits related to other syndromes.</p>
            <p> Ecology—  Mimosa amolariensis is characterized by robust underground structures above the rocky outcrops, phenolic compounds stored in its morphological anatomy, and high fruit production (Figs. 4 and 5). These traits are associated with the ability to permanency and regrow after periodic natural or anthropological fire events in Serra do Amolar and Serra de Santa Bárbara, including the presence of phenolic compounds, highly associated with protecting the species and increasing its tolerance to fire (Simon et al. 2009; Palermo  &amp; Miranda 2012; Lamont et al. 2018; Santacruz-Garcia et al. 2021a; Santacruz-Garcia et al. 2021b; Silva et al. 2021; Siqueira et al. 2023). The presence of phenolic compounds was detected in other fire-tolerant plants from the Brazilian Pantanal, such as  Cassia grandis L.f.,  Handroanthus heptaphyllus (Vell.) Mattos ,  Inga vera Willd. ,  Ocotea diospyrifolia (Meisn.) Mez ,  Rhamnidium elaeocarpum Reissek ,  Triplaris americana L.,  T. gardneriana Wedd. and  Vitex cymosa Bertero ex Spreng. (Silva et al. 2021; Siqueira et al. 2023). </p>
            <p> Etymology —The specific epithet  amolariensis refers to the location of the first recording of the species, the Serra do Amolar. </p>

            <p> Synopsis for the ser.  Piresianae (sensu Borges et al. 2022) </p>
            <p> Series  Piresianae Barneby.</p>
            <p> Type —  Mimosa piresii Barneby</p>
            <p> Subshrubs or shrubs, prostrate or virgate. Stems unarmed. Microphyllidious or macrophyllidious, usually with few ample leaves, long efoliate terminal panicles or racemes. Indumentum smooth or scaberulous, with glandular setiform trichomes in little species and resinous stems in  M. macropogon . Stipules firm or subfoliaceous, either lanceolate or narrowly triangular, the venation immersed. Leaves 1–28 jugate, and pinnae 5–42 pairs of leaflets. Blades 0.4–70 x 2.5–40 mm, 3–5-nerved. Globose capitula prior to anthesis either moriform or conelike; flowers 4-merous; calyx paleaceous-pappiform; corolla 2.6–5.45 mm, lobes 1-nerved; androecium diplostemonous, either cream-white or pink, shortly monadelphous. Pods subsessile or shortly stipitate, the shape linear, 25–66.15 × 5–9.55 mm, 4–12-seeded, the replum 0.4–2 mm wide; the articles either indehiscent or tardily dehiscent. </p>
            <p>Distribution —This series has ten species occurring in Neotropical Savannas, southern Brazilian Amazonia, Rupestrian Grassland and Tropical Forest, in Bolivia and Brazil, distributed at high or low elevations.</p>
            <p> Species—  M. aguapeia Barneby ,  M. amolariensis L.H.P.Nogueira, A.L.B.Sartori &amp; M.Morales ,  M. dasilvae A.S.L.Silva &amp; Secco ,  M. huanchacae Barneby ,  M. kuhlmannii Hoehne ,  M. macropogon Barneby ,  M. piresii Barneby ,  M. orbignyana Barneby ,  M. riedelii Benth. and  M. suberosa Atahuachi &amp; C.E.Hughes.</p>
            <p> Described by Barneby (1991), the  Piresianae series originally included only the species  M. kuhlmannii ,  M. macropogon , and  M. piresii . Subsequently,  M. dasilvae (Silva &amp; Secco 2000) and  M. suberosa (Atahuachi &amp; Hughes 2006) were added to the ser.  Piresianae because of their affinities to  M. piresii . Borges et al. (2022), through phylogenetic studies in clade O, which was detected in the studies of Simon et al. (2011), which included ser.  Pachycarpae and ser. Setosae, recognizing the monophyly of ser.  Piresianae with the inclusion of  M. aguapeia ,  M. orbignyana , and  M. riedelii , these three previously placed by Barneby in ser. Setosae. Although  M. huanchacae was not analyzed by Borges et al. (2022) in their study, we considered in it ser.  Piresianae because of the affinity with  M. aguapeia and the previous placement in ser. Setosae by Barneby (1993). Additionally, a sample of the specimen Simon 2326, which were previously identified as  M. aguapeia and considered here as  M. amolariensis , was located in the clade  Piresianae (Borges et al. 2022). It reinforces our hypothesis regarding  M. amolariensis belongs to the series  Piresianae . </p>

            <p> Distribution of ser.  Piresianae</p>
            <p> The ser.  Piresianae species, restrict only to South America, occur in low elevation forests and hill formations at Brazil and Bolivia. (Fig. 5).  M. piresii Barneby is widely distributed in the  Brazilian states of  Mato Grosso ,  Pará ,  Tocantins and Beni, across locations below 250 m als; in the mountains, the species occurs at higher altitudes, with records of occurrence between 750–820 m such as Canaã dos Carajás (Pará).  M. macropogon Barneby predominates in the southern forests of Amazonas, in lower altitude environments (50–185 m als).  M. kuhlmannii Hoehne and  M. dasilvae A.S.L. Silva &amp; Secco , respectively, have been recorded in Rondônia and Pará, but there is no precise information about their site of occurrence. </p>
            <p> In Bolivia,  M. orbignyana occurs on hills above 700 m als,  M. suberosa Atahuachi &amp; C.E.Hughes and  M. huanchacae Barneby are found in humid grasslands, Cerrado, and rocky outcrops of Campo Rupestre at altitudes of 200–850 m als.  M. aguapeia ,  M. orbignyana and  M. suberosa can be found in the Brazilian state of Mato Grosso, around the hills of Serra Ricardo Franco State Park.  M. riedellii was only recorded from the Chapada dos Guimarães, Mato Grosso.  Mimosa amolariensis occurs in the Serra do Amolar (Mato Grosso do Sul) and in the Serra de Santa Bárbara (Mato Grosso). </p>
