A new species of Cypella is described for the region of Camaquã river basin, in southeastern Rio Grande do Sul state, Brazil. The new species, named Cypella cruenta belongs to the section Cypella, being morphologically similar to the following species: Cypella Alonsoana, C. exilis and C. fucata. However, C. cruenta is easily recognized by its tepals with the concave portion and proximal half of the blade intensely painted in blood red, by the shape and size of the stamens and style with brief branches and with shorter crests, when compared with its similar taxa. Information on geographic distribution, ecology, conservation, uses and taxonomic relationships is provided. In addition, illustrations and a distinctive table among C. cruenta and its related species is presented. With the description of the new species, the genus Cypella now comprises 32 species, 17 of them belonging at section Cypella.<br /><br /></p> 2021-06-06T00:00:00-03:00 Copyright (c) 2021 Balduinia Anatomy of stem and root of Ipomoea cairica (L.)

Sweet (Convolvulaceae) - the Lianescent Vascular Syndrome. Among the Ipomoea species of economic importance, the liana Ipomoea cairica stands out because of its great pharmacological potential. Considering that the cambial variant present in Ipomoea is not causally related to the habit, the aim of this study is to list the group of anatomical features that define the “lianescent vascular syndrome” in the species, as well as to verify if there is variation between the stem and the root anatomy. Transverse and longitudinal sections of fresh material were analyzed qualitatively and quantitatively. Thus, it was found that the anatomy of the secondary xylem of I. cairica is similar to that of other species of Ipomoea, including indistinct growth rings, diffuse and porous vessels mainly solitary, simple perforation plate, alternate bordered pit, tyloses, heterocellular mainly uniseriate rays, and non-lignified parenchyma. The characteristics of the “lianescent vascular syndrome” is related to the high percentage of parenchyma. However, statistical analysis showed differences between stem and root in vessel diameter and vessel frequency, with higher values of vessel diameter and lower values of frequency of vessels in the root secondary xylem. These differences must be related to the environment in which the organ develops, as well as to the mechanisms involved in water conduction. Specific studies will make possible to test this hypothesis.</p> 2021-06-06T00:00:00-03:00 Copyright (c) 2021 Balduinia Rhamnidium Hasslerianum (Rhamnaceae) é nativa no Brasil 2021-10-27T18:19:52-03:00 Leonardo Paz Deble <p>Rhamnidium Hasslerianum (Rhamnaceae) é nativa no Brasil. Rhamnidium Hasslerianum é adicionado a flora brasileira, sendo sua ocorrência confirmada para a região central do estado do Rio Grande do Sul, onde foi encontrada em encostas rochosas e morros nos municípios de Júlio de Castilho e São Pedro do Sul. Rhamnidium passa a contar com quatro espécies nativas no Brasil. R. Hasslerianum é facilmente reconhecido por possuir hábito subarbustivo, e pelas folhas e verticilos florais com pontuações escuras.</p> 2021-06-06T00:00:00-03:00 Copyright (c) 2021 Balduinia Updates on geographic range and synonymies in species of Podocoma (Asteraceae: Astereae) 2021-10-27T18:19:52-03:00 Leonardo Paz Deble <p>Abstract. The geographic range of Podocoma Blanchetiana includes the sandy grasslands (Campos de Areia region), in Alegrete, Manoel Viana and São Francisco de Assis municipalities, southwest Rio Grande do Sul state, Brazil. Furthermore, Stenachaenium megapotamicum var. pedunculata and St. megapotamicum f. minor, are added to the synonymy of P. hieracifolia. Lectotypes are designated to St. megapotamicum f. minor and Podocoma Blanchetiana var. intermedia.</p> 2021-06-06T00:00:00-03:00 Copyright (c) 2021 Balduinia Cypella trimontina Ravenna (Iridaceae) a rare species micro-endemic in the Paraje Tres Cerros, La Cruz, northeast Argentina 2021-10-27T18:19:52-03:00 Leonardo Paz Deble Fabiano da Silva Alves <p>Resumen.
