Lentibulariaceae from Serra dos Pireneus, Goiás, Brazil¹

Abstract

This study provides a floristic survey of Lentibulariaceae occurring in Serra dos Pireneus (SDP), state of Goiás, Brazil. The phytogeographic domain in which SDP is located is the Cerrado, with different vegetation, including floodplain grasslands (campos úmidos) where Lentibulariaceae usually occur. Samples were collected from 2007 to 2010 and herbarium samples were consulted as well. We recorded nine species of Lentibulariaceae: the genera Genlisea (2 spp.) and Utricularia (7 spp.). Descriptions, illustrations, photographs and identification keys are presented in this study.

Introduction

Lentibulariaceae Rich. is a monophyletic family, belonging to Lamiales order (Müller et al. 2004; Cieslak et al. 2005; APG IV 2016) with a worldwide distribution, comprised in three genera, Genlisea A. St.-Hil., Pinguila L., and Utricularia L. (Taylor 1989; Heywood et al. 2007). Considered as carnivorous plants, their usual habitats are humid environments with nitrogen-poor soils, with terrestrial, aquatic and even epiphytic specimens (Taylor 1989).

Specimens of Lentibulariaceae typically occur in Cerrado, the second largest phytogeographic domain of Brazil and a hotspot for conservation (Myers et al. 2000; Klink & Machado 2005). This domain occurs at altitudes ranging from 300 m to over 1,600 m, with several different vegetation, including waterlogged habitats, the most suitable sites for the occurrence of Lentibulariaceae specimens (Taylor 1989; Ribeiro & Walter 2008). Nevertheless, natural areas of Cerrado have decreased over the years, mainly due to agricultural expansion (Miziara & Ferreira 2007). Therefore, the Cerrado biodiversity study is one of the most relevant topics on the agenda of conservation biology.

Taxonomic studies about Lentibulariaceae occuring in areas of Cerrado were conducted by Fromm-Trinta (1979, 1981, 1996, 2004), Mamede & Corrêa (2002), Guarçoni et al. (2006), da Silva et al. (2011) and Souza & Bove (2012), with new species of the family recently described by Bove (2008) and Souza & Bove (2011). The Brazilian Flora Group reports ca. 82 species, distributed in all Brazilian domains, and the Cerrado is the one with the highest number of species (BFG 2015).

To improve the biological knowledge and the distribution of the Brazilian Lentibulariaceae, we intend to provide a species list from Serra dos Pireneus, an area of conserved Cerrado. Herein we include a dichotomous key, diagnosis, pictures and illustrations of the Lentibulariaceae from Serra dos Pireneus.

Material and Methods

Serra dos Pireneus (SDP) is located among the municipalities of Pirenópolis, Cocalzinho de Goiás and Corumbá de Goiás (15^o40'S; 48^o45'W to 15^o45'S; 48°50'W), in the state of Goiás (Fig. 1), with minimum altitude of 700 m in the municipality of Pirenópolis and maximum of 1,385 m on Pico dos Pireneus. Rock formations in sandstone and quartzite, dated from the Precambrian period constitute SDP's main features, which have several types of Cerrado phytophysiognomies, including seasonally floodplain grasslands and swampy areas (veredas) (Siqueira 2004). According to the Köpper-Geiger classification, the region climate is Aw type (Kottek et al. 2006), annual rainfall average is 1,535 mm and annual average temperature is 24 ^oC (Climate-Data.org 2016).

In the study area, there is the Parque Estadual da Serra dos Pireneus, created by Brazilian Law 10.321/87, in order to "preserve the flora, fauna and springs therein, protecting natural sites of exceptional beauty and ensuring conditions of public welfare" (Goiás 1987). However, these protected areas are suffering many anthropogenic influences. There is an intense quartzite mining in SDP, destroying the organisms' natural habitats. Besides, the area is a touristic, folkloric and religious site, which enhance the flow of people and could compromise the ecologic interactions (Siqueira 2004; Bosquetti 2008).

Floristic surveys in SDP have been done since the eighteenth century (Pohl 1951; Saint-Hilaire 1975). Currently, projects about the regional flora of SDP are being conducted (e.g., Dantas-Queiroz et al. 2016) and this paper is part of this larger project.

Field trips were conducted in different months from 2007 to 2010, in order to locate individuals, collect and observe them in their natural habitats. The specimens were deposited in UFG herbarium. Collections from CEN, HEPH, IBGE, NY, UB and UFG (acronyms according to Thiers, continuously updated) were also analyzed. Morphological and ecological information were extracted from collected materials. Additional materials, when necessary, were properly referenced. The descriptions of the nomenclatural terms used were adapted from Taylor (1989) and Gonçalves & Lorenzi (2011). A dichotomous key was prepared containing the largest number of floral reproductive characteristics, since vegetative characteristics do not always provide important information. A map was conceived using QGis Desktop 2.12.3, with shapefiles available at IBGE website (IBGE 2016).

Results and Discussion

There are nine species of Lentibulariaceae in SDP, distributed in two genera: Genlisea (two spp.) and Utricularia (seven spp.). This data represents ca. 20% of all Lentibulariaceae species from the state of Goiás (BFG 2015).

The species occur mostly on floodplain grasslands, sometimes growing over rocks (Utricularia neottioides A. St.-Hil. & Girard). Many are associated with herbaceous vegetation, like Ceratophyllum L. (Ceratophyllaceae) and Poaceae, but also with other carnivorous plant, like Drosera L. (Droseraceae). The presence of specimens varies among the seasons, and individuals can be found with reproductive characters mostly during the rainy season. (October to May).
