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.

Two new species are described and illustrated from northeastern Argentina, and northern Uruguay. Neotypes are designated for Cypella discolor, C. fucata and C. laeta (based on collections made from the same locality as the holotypes indicated in the protologues). A lectotype is proposed for C. exilis, and an epitype is selected for C. pusilla. Further, three new synonyms are proposed: C. yatayphila under C. laeta, C. amplimaculata under C. exilis, and C. altouruguaya placed under C. lapidosa. Finally, C. osteniana subsp. aurantiaca is confirmed as a synonym of C. fucata.

A lectotype is designated here for Cocos poni, a species first proposed by Hauman in Las Palmeras de la Flora Argentina and currently treated as a synonym of Butia yatay or B. paraguayensis. Collections were made in the locality designated by Hauman based on his photos and description, and an epitype for this species is also designated here. Butia poni is recognized as a distinct species. This paper includes a description, photos, relationships, geographic distribution, and conservation assessment for Butia poni.

A new species of Calydorea is described and illustrated for northern Uruguay and southwest Rio Grande do Sul State, Brazil. This new species is closely related to C. nuda however, differs by its dark-blue or dark violet-blue flowers, stamens with white-cream filaments and bigger anthers, and style branches free towards the top. Data on phenology, geographic distribution, conservation, and habitat are provided. Moreover, a table to segregate this new species from its related species, and an identification key for the Calydorea species occurring in the sub-region of “Northern Campos” of Río de La Plata Grasslands are supplied.

Three new species of Cypella section Nais from South America are described and illustrated: C. charruana, C. gloriana, and C. uliginosa. Cypella charruana occurs in Santana do Livramento (southern Brazil) and in Rivera and Artigas (northern Uruguay). It is related to C. suffusa; however, it can be easily separated by its one-flowered spathes, outer tepals with narrowed claws, longer antheral filaments, and bigger anthers. Cypella gloriana is only found in São Vicente do Sul (central-western Rio Grande do Sul State, Brazil); this species is closely related to C. pusilla from which it can be separated by its larger perigone with shallower and broader concavity, outer tepals with narrowed claws, inner tepals with blades markedly narrowed and longer towards the apex, and with glandular trichomes spreading in a small area, stamens shorter, with porrect filaments, smaller anthers, and broader connective tissue. Cypella uliginosa occurs in bogs from Entre Ríos and Corrientes in northeastern Argentina; it morphologically resembles C. crenata and C. laxa; however, C. uliginosa can be distinguished from both species by its flowers with pale translucent and shallow central concavity, inner tepals blade plicate with a deep central depression, marked by a darker area covered by ochraceous glandular trichomes, and erect or slightly porrect style branches, with the stigmatic trichomes prolonged on the proximal portion of the adaxial crests. Cypella charruana and C. gloriana are recognized as critically endangered, while the data of C. uliginosa are insufficient to establish criteria of threat. Data about phenology, geographic distribution, conservation, plus comparative tables to segregate these three new species from the related taxa, and a key to differentiate species of the section Nais are supplied.

... Punta Ballena supported a high number of threatened and priority species for conservation, as well as endemisms, summing up 74 taxa, 17% of the site flora (Table 2, Fig. 4). According to IUCN criteria, Cypella osteniana, is considered endangered (Paz Deble et al. 2021) and five species are vulnerable: Oxypetalum marchesii (González et al. 2018) along with four Cacti: Parodia concinna, P. ottonis, P. scopa and Parodia sellowii (it should be noted that Parodia tabularis, was not evaluated by IUCN). A total of 33 taxa were considered priority for conservation in the country and 64 were identified as endemic: 48 regional endemisms, 13 with a restricted distribution within Uruguay and two local endemisms from Punta Ballena: Senecio ostenii var. ...

... Chauveau et al. (2012) in an important contribution for knowledge of the generic boundaries of Iridaceae family demonstrated the evolutionary trends in the flowers of the subfamily Iridoideae in the New World genera, and proved that the tribe Tigridieae is segregated into two large clades and Hesperoxiphion Baker, Larentia Klatt and Phalocallis belong to Trigridieae A, while Cypella belongs to Tigridieae B. In this same study, Cypella was recognized as polyphyletic and Cypella Hauthalii (Kuntze) Foster, Kelissa brasiliensis (Baker) Ravenna and Onira unguiculata (Baker) Ravenna are in a phylogenetic group distinct from the other Cypella species. Deble et al. (2012Deble et al. ( , 2015aDeble et al.

In two recent studies, Deble & Alves (2020) and Deble (2021b) demonstrated that anatomical and morphological attributes such as roots, bulbs, shape of the spathe valves and leafy-anatomy corroborate the molecular data found by Chauveau et al.

... Few studies have demonstrated the importance of fruits and seeds for taxonomic distinction within the tribe Tigridieae. Deble (2021) highlighted the morphological particularities of the capsules of Kelissa brasiliensis and Onira unguiculata, as they have thick and markedly angled walls, while Deble et al. (2015) and Deble et al. (2018) indicated that the seed texture (honeycomb or smooth) is a character for distinguishing species in Cypella and Calydorea, respectively. In Cypella, the capsules are obovate or oblong, with non-angled margins and a thin or membranous wall. ...

Calydorea Herbert (1843, p. 85) is a genus of small seasonal perennials plants centered in temperate South America (Roitman & Castillo, 2005, 2007Deble, 2011;Deble et al., 2013Deble et al., , 2016, and according with the World Check List of Iridaceae (WCI) includes 21 species (Barker, 2018). The genus can be morphologically characterized by its deceptively simple flowers, recognized by the absence of lipid trichomes, free stamens, curved or twisted anthers at dehiscence, and filiform style branches that often extend between the stamens, and ending in one obtuse or shortly emarginated stigmatic area (Ravenna, 2003(Ravenna, , 2005(Ravenna, , 2009Goldblatt & Manning, 2008;Chauveau et al., 2012). ...
