| 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... |

| A new species of Uncinia (Cyperaceae), U. austroamericana, is described and illustrated from austral South America and from the Tristan da Cunha archipelago in the south-Atlantic Ocean. This species grows in persistently wet, base-poor sites, particularly in Sphagnum bogs, and is known from southern Patagonia, Tierra del Fuego, and from the largest island of the Tristan da Cunha group. It differs both morphologically and ecologically from the similar-appearing U. macrolepis, a minerotrophic species best known from moist depressions in grasslands. The new species differs morphologically from U. macrolepis by possessing achenes that, when mature, are pale-colored and conspicuously-thickened at the apex and, also, by having more or less loosely-flowered... |

| This is the first revision for the representatives of the genus Caiophora (Loasaceae) in Chile. The genus is widely distributed in the Andes from Argentina/Chile in the South to Central Ecuador in the North, and comprises approximately 60 species. In Chile only five species are present, Caiophora chuquitensis, C. cirsiifolia, C. coronata, C. deserticola sp. nov. and C. rosulata. Caiophora rosulata is here subdivided into two subspecies: western Andean C. rosulata subsp. rosulata (present in northern Chile and southern Peru), and eastern Andean C. rosulata subsp. taraxacoides, stat. and comb. nov. Furthermore C. superba syn. nov. and C. macrocarpa syn. nov. are placed into synonymy under C. chuquitensis, and C. rahmeri syn. nov. is synonymized to C.... |

| In a survey of Agaricales fungi in Seasonal Semidecidual Forest remnants from Paraná State, southern Brazil, two Clitocella and two Rhodocybe species were identified. Based on morphological data, Clitocella pallescens is described as a new species, and a new combination is proposed to Clitocella himantiigena. Rhodocybe galerinoides and C. himantiigena are new records from Brazil. Rhodocybe caelatoidea, already registered in Paraná State, is also described, illustrated and discussed. |

| Ten members of the tribe Cariceae (Cyperaceae) occur on the Juan Fernández Archipelago: four species of Carex and six of Uncinia. Eight of the ten species occur on Alejandro Selkirk Island (= Masafuera; 50 km2) while four are known from Robinson Crusoe Island (= Masatierra; 48 km2). Carex fernandezensis, C. stuessyi, Uncinia aspericaulis, and U. macloviformis are newly described from the archipelago and all are endemic to the islands. Only two species, Carex berteroniana and Uncinia douglasii, both endemics, are of frequent occurrence and each occurs on both islands. Another endemic, Uncinia costata, is known only from the type locality on Alejandro Selkirk. The three remaining species, Uncinia phleoides, U. tenuis, and Carex phalaroides, the last here... |

| The holotype of Carex sagei comes from central Chile, and this name has long been treated as a synonym of C. fuscula. Recent study indicates, however, that C. sagei is referrable to Carex section Ceratocystis, whereas C. fuscula belongs in section Spirostachyae. It is also demonstrated that C. sagei is the correct name for plants currently called C. barrosii. Carex sagei is known from Argentina, Chile, and the Falkland Islands (Islas Malvinas), where it frequents hydric habitats, such as marshes, wet meadows, and the margins of lakes, from near sea level to about 850 m. |

| Munroa is a morphologically heterogeneous American genus of grasses, including five species with disjunct distribution in North and South America. Dasyochloa is a monotypic grass genus, common in western North America, with a controversial taxonomic position, because it has been alternatively included in Erioneuron, Koeleria, Triodia, and Uralepis. We evaluated the relationship of Dasyochloa with Munroa using a phylogenetic analysis of qualitative and quantitative morphological data. Dasyochloa was not supported as an independent genus from Munroa, as Dasyochloa and Munroa species formed a monophyletic group defined by seven synapomorphies. On this basis, we transfer Dasyochloa to Munroa, and propose the new combination M. pulchella together with the... |

| kleinii is similar to a group of terrestrial species characterized by their small pseudobulbs, buried underground, and small flowers, but it can be distinguished by the color of its flowers, lip lateral lobes slightly or not falcate and subequal in length and width, lip midlobe base with little or no constriction, and geographical distribution. Cyrtopodium brandonianum subsp. lageanum is similar in general flower color to typical C. brandonianum, but it can be distinguished by its earlier flowering, leaves poorly developed at anthesis and different shape and colour of the lip. Both taxa are rare and only known from southern Brazil. |

| Fifty native and 12 naturalized species of Lepidium grow in South America, and a key to all 62 species is presented. Three new species from Argentina (L. hickenii, L. pedersenii, and L. santacruzensis) and two from Peru (L. cuzcoensis and L. werffii) are described, illustrated, and their relationships to nearest relatives are discussed. The new combination Lepidium crassius is proposed. Furthermore, 19 taxa (Coronopus didymus var. macrocarpus, C. didymus var. procumbens, L. abrotanifolium var. steinmannii, L. affine, L. argentinum, L. auriculatum, L. bonariense var. pseudovirginicum, L. calycinum var. integrifolium, L. costaricense, L. cumingianum var. orbiculatum, L. cumingianum subsp. berteroanum, L. depressum, L. myrianthum, L. neglectum, L. parodii, L.... |

| La pitahaya es una cactácea que se cultiva en zonas con clima tropical, subtropical o semiárido de México. Tres especies tienen importancia económica como frutales. En Tepoztlán, Morelos, se encontraron plantas con síntomas causados por patógenos y daño por insectos. Debido a la importancia actual y potencial del cultivo y la incidencia de plagas y patógenos, se realizó el presente estudio con el objetivo de identificar taxonómicamente y describir daños de los principales agentes fitosanitarios asociados Hylocereus spp. Durante 2006-2008 se recolectaron mensualmente estructuras vegetativas y reproductoras dañadas; de 2007-2010 se aislaron e identificaron microorganismos (22± 1.5°C) e insectos (25 ± 1.5°C, 45 % HR y fotoperiodo 14:10) en laboratorio. En... |
