| 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... |

| 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... |

| We present relevant data about the taxonomy and distribution of 20 species of the genus Carex in the Neotropics from the Caribbean region to Patagonia. We provide a total of 19 new records, two of them for species not previously recorded from South America, ten species newly reported from different countries, and seven species here reported as new regional records in Argentina, Bolivia, and Chile. We lectotypify nine species names (C. brehmeri, C. catharinensis, C. ecuadorica, C. firmicaulis, C. fuscula, C. mandoniana, C. phleoides, C. polysticha, and C. subantarctica) and epitypify one of these names (C. fuscula). Finally, we propose Carex koyamae as a new synonym of Carex phleoides. |
