This list is compiled from Ken’s notes of the plants he collected and grew over a period of many years, transcribed by Alison Evans, who along with Mary Gibby has also checked many of the ferns against the list. It has not yet been possible to check all of them; however all these are currently thought to be extant. Roger Golding has edited the list for presentation here. There have been some name changes during this time, not all of which are reflected in Ken’s notes, and these been updated where possible. In doing so some errors or misapprehensions may have crept in, for which RG takes full responsibility. Most of Ken’s notes have been included verbatim, with some additional notes in square brackets for clarification purposes. Ken gave provisional names to many forms of the Dryopteris affinis group to distinguish them; some of these have since been given formal status at one level or another; there are many others whose taxonomic status remains to be clarified. This collection forms an invaluable reference for students of the group.

The garden is laid out in four main sections with each plant assigned a number. These are referenced in the final column as follows:

A: Main Fern Bed; B: Main Fern Bed, Rear Portion; C: Wood Collection; D: Embankment Fern Bed.
