We report here new records of occurrence of Hindsia ramosissima Gardner (Rubiaceae), expanding the species area of distribution in the Brazilian state of Santa Catarina. We also provide an assessment of the species conservation status. We performed eight collections at five municipalities of Santa Catarina, thereby considerably expanding the austral limit of the species extent of occurrence.Keywords: Atlantic Forest, biodiversity, campos rupestres, conservation status, distribution. RESUMO: (Novos registros de Hindsia ramosissima Gardner (Rubiaceae) e avaliação dos status de conservação para Santa Catarina, sul do Brasil). O presente estudo destaca novos registros de Hindsia ramosissima Gardner (Rubiaceae), ampliando a sua distribuição para o estado de Santa Catarina, Brasil, além da avaliação do status de conservação. Foram registradas oito coletas em cinco municípios de Santa Catarina, expandindo consideravelmente o limite austral da espécie.Palavras-chave: Biodiversidade, campos rupestres, distribuição, Floresta Atlântica, status de conservação.Received: July 17, 2018    Received after revision: September 16, 2019      Accepted: September 21, 2019 Available on-line at http://www.ufrgs.br/seerbio/ojs/index.php/rbb/article/view/4128INTRODUCTIONHindsia Benth., one of the less representative genera of the Rubiaceae, is an endemic genus to Brazil whose representatives are characterized by having small size and shrubby habit (Delprete & Jardim 2012). The genus has only 11 recognized species (Flora do Brasil 2020 under construction 2019): Hindsia arianeae Di Maio, Hindsia cucullata Di Maio, Hindsia glabra K. Schum., Hindsia ibitipocensis Di Maio, Hindsia irwinii Steyerm., Hindsia longiflora (Cham.) Benth., Hindsia phyllocalyx K. Schum., Hindsia ramosissima Gardner, Hindsia republicana Di Maio, Hindsia sessilifolia Di Maio, and Hindsia violaceae Benth. These species have been reported to occur in the Brazilian states of Bahia, Minas Gerais, Rio de Janeiro, Paraná and Santa Catarina (Flora do Brasil 2020 under construction 2018).According to the List of Species of the Brazilian Flora (Flora do Brasil 2020 under construction), only H. lon-giflora occurs naturally in the Brazilian southern state of Santa Catarina. However, Delprete et al. (2005) also reported H. ramosissima to campos rupestres from the Cambirela mountain at Palhoça municipality, as well as to an unknown municipality at the borders of the Serra Geral mountain range (Delprete et al. 2005).Thus, we aimed to report new confirmed records of occurrence of H. ramosissima to Santa Catarina state, thereby increasing the species extent of occurrence; and assess the species conservation status.MATERIAL AND METHODSWe conducted field works across the Serra Geral mountain range in Santa Catarina, southern Brazil, from July 2009 through December 2017, in order to estimate occupancy patterns of H. ramosissima in the state. Addi-tionally, we consulted herbarium collections to confirm other sites of occurrence of the species in Santa Catarina.To assess the species conservation status in Santa Catarina, we performed analyses in software GeoCAT (Geospatial Conservation Assessment Tool) using both herbarium data and our field observations.RESULTS AND DISCUSSIONDuring the field work of November 27, 2013, we found ca. 30 fertile individuals of H. ramosissima in campos rupestres at Treviso municipality (Fig. 1).Additionally, we also obtained seven more records from collections previously performed at four municipali-ties across Santa Catarina state: Nova Veneza, Palhoça, Santo Amaro da Imperatriz, and Urupema (Fig. 2).All individuals were collected on rocky outcrops from campos rupestres, at 742 to 1700 m altitude, and had their identities confirmed through the analysis of high-resolution images obtained from herbarium collections (herbaria FLOR, FURB, HUEFS, ICN, MBM and NY) (Table 1).Furthermore, from June through July 2017 we also New records of Hindsia ramosissima Gardner (Rubiaceae)and assessment of the species conservation status inSanta Catarina state, southern BrazilNew records of Hindsia ramosissimaR. bras.

Collection sites in Santa Catarina state, southern Brazil, of herborized specimens of Hindsia ramosissima Gardner (Rubiaceae).observed two populations with individuals at vegetative state, which were therefore not collected for herbaria, in two locations at southern Santa Catarina state: one at Serra Furada State Park (28º10’12” S – 49º 23’34” W, at 805 m altitude), in Grão Pará municipality; and the other at Funil Canyon, in Bom Jardim da Serra municipality (28º20’52” S – 49º31’54” W, at 1380 m altitude).Regarding the species conservation status, Delprete et al. (2005) reported H. ramosissima to be Critically Endangered (CR) in Santa Catarina, since only one population was then known. However, with our findings the species may be considered Endangered (EN), under criteria B2ab (i, ii, iii, iv), with EOO = 2,924.593 km² and AOO = 20 km². H. ramosissima populations are under constant threat not only by forestry, agriculture and cattle-raising, but also by anthropic activity, espe-cially due to the presence of trails in the species habitat (Vibrans et al. 2013).Our findings increase the knowledge on H. ramosis-sima and on the flora of campos rupestres from Santa Catarina. Moreover, the confirmed records of herbarium collections along with our field observations altogether expand considerably the extent of occurrence of H. ra-mosissima in the state, thereby determining a new austral limit for the species. Lastly, we suggest the performance of a review on the genus, which will enable a better delimitation of the specimens collected in the campos rupestres of Santa Catarina.REFERENCES DELPRETE, P.
