This scries of “Floristische Notities” contains with a few exceptions acquisitions to the flora of the Netherlands from the year 1959. Mentioned are; 68. Alnus glutinosa (L.) Vill. f. quercifolia (Willd.) Koehne; a case of the occurrence in a wild state of this not rarely cultivated form. 69, 70, 72, 73, 74, 76, 77, and 78. Dysphania myriocephala Benth., Amaranthus macrocarpus Benth. var. melanocarpus Thell., Glinus lotoides L., Verbena supina L., Calotis cuneifolia R.Br., Matricaria intermedia (Hutchinson) Van Ooststr. & Reichg., nov. comb. ( Pentzia intermedia Hutchinson), Cyperus exaltatus Retz., and Cyperus dactyliformis Boeck. First records of these wool-aliens for the Netherlands; all found along the river Meuse near Itteren in the province of Limburg, together with a large number of other adventitious species. 71. Lepidium pseudo-didymum Thell. Found for the first time in the Netherlands in 1950 and again in 1958 near wool-factories at Tilburg. This species was described by Thellung from Galashiels, Scotland, the native country being unknown. It now appears to be identical with Lepidium inclusum Schulz from Patagonia and Tierra del Fuego. 75. Erigeron acer L. X E. canadensis L. (E. X hülsenii Vatke) was discovered on a railway-yard near Stavoren, where it grew in some quantity together with the putative parents. 79. Pulmonaria rubra Schott and Crocus tomasinianus Herb., both escaped from cultivation.
