It is now ten years since I wrote the article "The Cryptocoryne albida group of Mainland Asia" in the "Liber Gratulatorius" on the occasion of the retirement of Prof. H. C. D. de Wit (Jacobsen, 1980). Very little new information about these species has in the meantime come to our knowledge; all the plants imported to Europe during the last 10 years have added only few new facts, most of the material confirming what we knew or suspected around 1980. Our information about the variation within the species has increased, but not more than what was to be expected.

The following account presents an abbreviated version of what was contained in the article 10 years ago, supplemented by the additional information obtained since then. The intervening time has also shown a need to be able to recognize some of the intraspecific variation found within the polymorphic species C. crispatula.
