Collection method comments: 'Most of the material described in this paper was collected during the Nugssuaq Expeditions in 1938-1939 and during the current geological mapping of Svartenhuk and Nugssuaq under the auspices of the Geological Survey of Greenland. Both were carried out under the leadership of Professor A. Rosenkrantz.' The author himself joined two of the expeditions.
