Abstract
There have been occasional records of flore pleno forms of Sagina procumbens from Britain and Ireland for 200 years. Druce assigned these forms the varietal name var. daviesii, and a lectotype is designated here. A varietal rank cannot be maintained for this form, which becomes forma daviesii stat. nov. The records and observations on this variety are reviewed, including a new report from vc110 (Outer Hebrides), and the distribution is summarised.

Acknowledgements
I am grateful to Arthur Chater for advice on the identity of my Sagina specimen, and setting me off on the trail which led to this paper. I would also like to thank the keepers at BM and E for access to specimens, and Herbaria@Home for making wider herbarium information readily available. Helpful comments from two reviewers led to a substantially improved paper.
