| 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... |

| Chilean Robinson Crusoe Island is a semi-isolated location with unusually high rates of both consanguinity and language disorder. The current population of 633 inhabitants is descended almost exclusively from the colonization at the end of the 19th century, as there were few preceding immigrations to the island. This study investigates the genetic composition and degree of miscegenation within the island population, using dental morphological markers. The universe of island children was studied (n= 128, 3 to 15 years of age) using clinical exams, dental cast, and identification of each individual within a previously-constructed extensive genealogy for the island. The frequencies for Carabelli's cusp (61.7%), shovel-shaped incisor (9.4%), and sixth cusp... |
