Noona Dan Expedition. In April 1961 the Danish schooner Noona Dan with a staff of 19, three of them botanists, left Copenhagen to explore in the Philippines during August and September on Palawan, then for two weeks on Balabac, then for a month on Tawitawi; the last two weeks of the year were spent near Zamboanga in Mindanao. The first half of 1962 was spent in the Bismarck Archipelago. In the middle of August, the Solomon Islands were visited; in September-October the expedition members returned to the University of Copenhagen. About 5000 herbarium specimens were collected; especially during the last part of the expedition attention was paid to fungi (T. Wolff in Nature 198, 1963, 1044-1045).
