Galanthus elwesii Hook. f. in de provincie Utrecht Naturalis
Raamsdonk, L.W.D. van.
Galanthus elwesii Hook. f. was first found in the Netherlands in 1941. Up to now only two country seats are known where G. elwesii is still growing, one of them being in the province of Utrecht. This paper deals with the occurrence of four new localities in the province of Utrecht, where O. elwesii appears to be naturalized on two of them. The accompanying species on the natural localities are mainly characteristic of the Ulmion-Carpinifoliae vegetation, with sometimes a slight transsition to the Agropyro repentis-Aegopodietum podagrariae vegetation. Chromosome numbers counted are in accordance with those reported in the literature. The place in the Standard List of the Netherlands Flora is discussed. Based on the new data G. elwesii appears to belong to...

Korte mededelingen Naturalis
Gadella, T.W.J.; Raamsdonk, L.W.D. van.
Nieuwe vindplaatsen van Hieracium peleterianum Mérat. Tot dusverre werd het Schellings havikskruid (Hieracium peleterianum) alleen aangetroffen op Terschelling en wel in het gebied tussen Formerum en de Tweede Duintjes van de Boschplaat. Een groot aantal exemplaren werd in augustus 1982 gevonden tussen paal 8 en het gebied van de Noordvaarder op een grazig pad door de duinen ter hoogte van paal 7. Dit betreft een nieuwe vindplaats in een uurhok, waarvan de soort nog niet bekend was. Ook werd bij Formerum aan Zee aan de rand van de Formerumse heide een nieuwe, flinke groeiplaats ontdekt in een uurhok, waarvan de soort overigens reeds bekend was. De grote vindplaats ten zuiden van het Hoornse bos is door bouwactiviteiten aldaar helaas verloren gegaan.

Ornithogalum umbellatum L. en O. divergens Bor. in Nederland Naturalis
Gadella, Th.W.J.; Raamsdonk, L.W.D. van.
In the Netherlands two groups of plants can be distinguished in Ornithogalum umbellatum L. s.l., which differ morphologically and cytologically. The first group consists of triploids and some tetraploids, the second of penta- and hexaploids and also some tetraploids. The characters of the triploids (2n = 27) are: bulbs higher than broad; bulbils few and oblong; more than 15 leaves (up to 5 mm broad) per bulb; inflorescences few-flowered (5—12 flowers); pedicels not deflected after anthesis. The characters of the penta- and hexaploids (2n = 45, 54 respectively) are: bulbs broader than high; bulbils many, small and round; leaves up to 12 (5—8 mm broad); inflorescences many-flowered (usually more than 14 per inflorescence); pedicels always deflected after...
