“…Cypella luteogibbosa es fácilmente reconocida por sus espatas unifloras, flores con perigonio blanco o blanco-ocráceo y tépalos internos con una joroba de color amarillo. Cypella luteogibbosa se encuentra En Peligro, debido su rareza y amenazas como el sobrepastoreo y explotaciones de canteras para extraer material de rutas (Eggers et al, 2019 Plantas de 10-25 cm de altura, tallos subterráneos de 3-6 cm. Bulbos 16-30 × 15-25 mm, globosos u ovoides, prolongado en un collar de 2-4 cm; catáfilos anchamente ovado-lanceolados, agudos o acuminados en el ápice, de color marrón claro o parduzco.…”

The genus Cypella is studied for the Uruguayan Flora. Based in revision of Herbaria and collections sampling were recognized 13 species and five subspecies for the country: C. alonsoana, C. aurinegra subsp. aurinegra, C. aurinegra subsp. albipurpurata, C. charruana, C. discolor, C. exilis, C. fucata, C. guttata, C. herbertii subsp. herbertii, C. herbertii subsp. brevicristata, C. herbertii subsp. reflexa, C. laeta, C. laxa, C. luteogibbosa, C. osteniana and C. rivularis. Cypella aurinegra subsp. albipurpurata comprises a new subspecies endemic in rocky place, on Mountain Range in Cerro Largo Department, Northeast Uruguay. Cypella laxa is a new record for the country. It is supplied dichotomous key, descriptions, material examined, comments and photos for all taxa identified. Furthermore, ecological data, conservation status, excluded species and other taxa with possible occurrence in Uruguay are listed.

“…More recently, other botanists have contributed to the knowledge of the group in the regional context, including the description of new species, revision of genera, phylogenetic studies, and conservation studies (Goldblatt 1978, Roitman & Castillo 2004, Roitman & Castillo 2005, Roitman & Castillo 2007a, Roitman & Castillo 2007b, Roitman & Castillo 2008, Roitman et al 2008, Eggers 2008, Hurrel et al 2009, Deble et al 2012a, Deble et al 2012b, Deble et al 2012c, Chauveau et al 2012, Deble & Alves 2013, Bonfada-Rodriguez et al 2014, Deble et al 2015a, Deble et al 2015b, Deble et al 2016, Deble & Alves 2017, Deble 2017, Pastori et al 2018, Eggers et al 2019, De Baltezan et al 2019 As can be seen, the bibliographic references that contemplate the Iridaceae-Tigridieae in the Campos of SESA are relatively abundant. However, there are still few studies that address the diversity of Iridaceae-Tigridieae as a whole in the region.…”

Survey on the tribe Tigridieae (Iridaceae) in the Campos of Southeast South America (SESA Grasslands). Iridaceae is one of the largest families of monocots and is an important constituent of grassland ecosystems across the globe. The tribe Tigridieae is exclusive to the Americas, with an important center of diversity in the Andean region, in the Campos of Southeast South America, in Mexico and in the southern United States. In this study, a survey of the Iridaceae-Tigridieae native to the Grassland Ecosystems of Southeast South America (=SESA Grasslands) is carried out. The SESA was divided into four regions: Campos, Campos de Altitude, Chaco Húmedo and Pampa. The Iridaceae-Tigridieae are represented by a total of 65 species (including ten subspecies), distributed in ten genera. The genus Cypella with 30 species and eight subspecies is the most diverse, followed by Calydorea (13 species), Herbertia (11 species) and Gelasine (four species and two subspecies). A total of 87% of the taxa occurring in the SESA are endemic, most of them exclusive to the Campos region, which includes 54 taxonomic entities, of which 41 taxa are endemic The Campos de Altitude region is represented by 15 taxa, including six endemic species. The Pampa region includes six taxonomic entities, being one of them endemic. The Chaco Húmedo region comprises five species, none of which are exclusive to the latter region. Key words: Bulbous, Grasslands, High Grasslands, Humid Chaco, Geographic distribution, diversity, Pampa.

Flowers producing oil resources and oil bee pollinators are involved in one of the most specialized pollination strategies. Various species of Iridaceae tribe Tigridieae are characterized by floral oil-secreting structures called elaiophores, but specialized plant–pollinator interactions among these taxa remain poorly understood. This study focused on four South American species of Tigridieae in three genera to assess the nature and extent of ecological specialization related to oil flower/oil bee interactions. Proportion, frequency and behaviour of specialist and generalist pollinators were investigated, and experiments on plant breeding system and observations on floral biology were conducted. Species of Arhysoceble (specialist bees) and Halictidae (generalist bees) formed the most representative taxonomic groups of pollinators. Even though ecological specialization for oil bees was detected in Cypella amplimaculata and Cipura sp., contrasting patterns of specialization were observed not only among the different plant species studied but also between populations of Herbertia pulchella and Cipura formosa. Self-incompatibility was reported for H. pulchella and Cipura sp., whereas C. amplimaculata and C. formosa presented a mixed-breeding system. However, all species were pollinator dependent and patterns of ecological specialization were not dependent of plant breeding system. This study revealed also that interactions between oil bees and elaiophores are not reliable predictors for efficient pollination.
