Over het voorkomen van Sedum forsterianum Smith in Nederland
Gorteria Dutch Botanical Archives , Volume 6 - Issue 4 p. 67- 72
Recently Sedum forsterianum Sm. was excluded from the Dutch floras, because its occurrence in the Netherlands was doubted. This species, which resembles Sedum reflexum L. very much in habit, differs from the latter in the shape and attachment of the leaves on the non-flowering shoots and in the shape of the sepals and petals. Its stamens and carpels are smooth instead of papillate. In addition the two species have a different basic chromosome number. S. forsterianum occurs rather frequently in regions adjacent to the southern part of the Netherlands. In the last century it was also found in this country. The author is of the opinion that S. forsterianum might still be found in the Netherlands, and asks for reports of eventual finds.
