The Lycopodiales of Britain and Ireland (Diphasiastrum, Huperzia, Isoetes, Lycopodium, Selaginella)

L. Watson and M.J. Dallwitz

Introduction

This data set is generated from a DELTA database (Dallwitz 1980; Dallwitz, Paine, and Zurcher 1993). It comprises descriptions of all the species, illustrated mainly from Sowerby and Johnson (1859 and 1863), and a file of source references. The descriptive data are mainly from Bentham and Hooker (1945 ed.), Clapham, Tutin and Warburg (1962), and Stace (1997), and the nomenclature and classification are aligned with Hassler and Swale’s (2003) world species list. Higher-resolution versions of many of the images are available if needed.
