Tetroncium magellanicum (Juncaginaceae) was described by Willdenow in 1808, based on material collected by Commerson at the Strait of Magellan during Bougainville\&$\#$39;s voyage around the world. Type material of this species was traced and a lectotype for the name is designated. A description of the species and notes on its ecology and conservation status are provided. For the first time, a detailed map showing the known distribution area of T. magellanicum is presented.

The extraordinarily wide distributional ranges of aquatic flowering plants have long stimulated phytogeographical discussion. Although aquatic plants occur rarely among the angiosperms, they represent a disproportionately large number of taxa with broad distributions including various intercontinental disjunctions that are manifest even at the species level. Throughout the nineteenth and early twentieth centuries, long-range dispersal by waterfowl was the prevailing explanation for widespread aquatic plant distributions. This explanation gradually fell into disfavor as biologists raised doubts as to the ability of waterfowl to transport propagules across the extensive transoceanic distances between the continents on which an assortment of aquatic taxa now reside. During the twentieth century, the development of biogeographical displacement theory, i.e., \“continental drift,\” steadily began to supplant dispersal as the preferred explanation for discontinuous angiosperm distributions. Our study assesses the dispersal/displacement hypotheses from a temporal standpoint using molecular estimates of divergence time for a diverse sample of phylogenetically related aquatic taxa that exhibit discontinuous intercontinental distributions. With few exceptions, we found divergence times that are far too recent to implicate continental drift as a major determinant of discontinuous distributions in aquatic plants. We suggest that long-distance dispersal by birds should continue to be regarded as a viable explanation for widely disjunct aquatic plant distributions, although such dispersal is likely to have involved a combination of overland as well as transoceanic migratory routes.

This paper provides the first comprehensive, updated account of the Falkland Islands native flora for nearly forty years. 171 species are recognised, thirteen of which are endemic. Seven native species are included in the checklist for the first time: Arachnitis quetrihuensis Dimitri, Carex banksii Boott, Carex barrosii Nelmes, Elatine sp., Plantago moorei Rahn, Ruppia filifolia (Phil.) Skottsb. and Viola magellanica Forst. f. The presence of Rumex magellanicus Campd., a record previously considered doubtful, is also confirmed. Three previously reported native species are believed to have been recorded in error for the Falkland Islands, and are removed. These are, Eleocharis albibracteata Nees \& Meyen ex Kunth, Plantago maritima L. and Schizaea fistulosa Labill. The checklist provides the first detailed account of the ecology, phenology, distribution and status of the vascular plant flora, and as such is a unique record of the Falkland Islands flora at the beginning of a period of unprecedented economic and social change.

Juncaginaceae are a small monocot family of mostly coastal and wetland herbs of almost cosmopolitan distribution. A phylogenetic analysis of the family and members of Alismatales was conducted to clarify the circumscription of Juncaginaceae and to understand intrafamilial relationships. For the first time, all genera associated with the family in the past were analysed together. Two plastid (rbcL and matK) and one mitochondrial gene (atpA) were sequenced. The separate and combined analysis of the three markers showed that Juncaginaceae are not monophyletic in their current circumscription. The family is re-circumscribed to exclude Maundia which is proposed to belong to a separate family Maundiaceae. In the new classification Juncaginaceae comprise three genera: Tetroncium, Cycnogeton, and Triglochin. Tetroncium is weakly supported as sister to the rest of the family. The reinstated Cycnogeton (formerly included in Triglochin) is highly supported as sister to Triglochin s.s. The enigmatic Lilaea is nested within Triglochin s.s. and highly supported as sister to the T. bulbosa complex. The results of the molecular analysis are discussed in combination with morphological characters. A key to the genera of the family is presented, and six new combinations are proposed: Cycnogeton alcockiae, Cycnogeton dubium, Cycnogeton microtuberosum, Cycnogeton multifructum, Cycnogeton rheophilum, and Triglochin scilloides.
