The present study deals with a part of the results of observations made during expeditions in 1968 and 1969 to the Angmagssalik District, the central and largest deglaciated area on the Southeast coast of Greenland; which journeys were preceded by a reconaissance in 1966. The Angmagssalik District is a very mountainous area deeply cut by numerous fjords, and has a pronounced oceanic low-arctic climate. Its general physiography has no broad beaches and wide saline deltas where such extensive, luxuriant and very diversified littoral vegetation as those known from southern latitudes might develop. However, well-developed small stands are locally common in suitable, sheltered habitats and represent several clearly distinguishable vegetation types. The... |

Tetraplodon mnioides (Hedw.) B.S.G. is recorded from the Netherlands for the first time. The occurrence in the lowland of the northwestern european continent of this species and the related Splachnum ampullaceum Hedw., which occurred in the Netherlands in former times, is briefly outlined on the basis of records in literature. Consequently three areas in the Netherlands are indicated where these interesting nitrophilous Splachnaceae may possibly be discovered or rediscovered. |

From a bryological point of view Greenland is not well known in detail. Unlike Siberia or Arctic America, it is not known through a few large collections, but through multitudes of mostly relatively small gatherings. In this arctic island that is almost 2000 miles long and extends from below 60° N.lat. to nearly 84° N.lat., travel and logistics are difficult. Consequently no over-all study of the whole island has been made, although many collections have been achieved through casual or intensive studies of small areas. Like the other contributions to the knowledge of the bryoflora of Greenland this paper will only deal with a rather limited area; the Angmagssalik district on the East coast of Greenland, ranging from 65° N.lat. to 67°20' N.lat. In 1887... |

As delimited by Polunin (1951), the Arctic is situated on the Northern hemisphere North of (1) a line 50 miles North of the coniferous forest line, (2) the Northern limit of microphanerophytic growth, or (3) the Nordenskjöld line, according to the formula V = 9-0,1K. According to this delimination the whole of Greenland belongs to the arctic region. Within the Arctic a subdivision in low- and high-arctic regions is usually recognized. Larsen (1960) marks this transition on the East coast of Greenland near Cape Dalton. Low-arctic East Greenland thus stretches from 60° to 69°30' N. lat. The Angmagssalik area in Southeast Greenland ranges from circa 65° to 67°20' N. lat. Between the Sermilik and the Kangerdlugssuatsiak fjords to the West and East, Denmark... |
